First a little about myself. I am not an experienced software engineer, architect or developer. I have done mostly small ASP and ASP.NET projects in C# for the last 5 years. I am pretty good with HTML and JavaScript. These projects were done when I had free time from my other duties which were not related to software development. I have now been moved into a software developer position. The company I work for is not a software development firm.
I am now working on a Silverlight LOB application with WCF and Entity Framework. I have been given little specifications for this project, just the 'make an application like X, only simpler so we don't have to pay for it', my boss doesn't check on my progress as often as I think he should, the project manager(a co-worker) will stop by now and then but we never discuss the specs, architecture, UI or business rules. I am mostly just asked when I think it will be done. I have had to learn Silverlight, WCF and Entity Framework to work on this project which is not a problem as I really enjoy working with these technologies. The problem is I am the only one in the company that knows anything about these and have no mentor/boss to discuss the problems and how they could be solved. I have been able to seek out one interested party in the company that has at least given me a list of some of the requirements.
I can't believe this is how software development should be done. I think the project managers should offer guidance and keep a closer eye on what is being done to prevent going in the wrong direction(but how can they in my situation since the don't know the technologies!).
Should I feel this way or am I way off base?
Thanks for listening.
What you describe is certainty not optimal, but it's extremely common, particularly in smaller shops. Some people find it rewarding to work in that kind of environment. It's not what the software engineering books teach, but that's why there are so many software engineering books.
If you want to continue working in this environment, you're going to have to supply all the discipline you rightly recognize as missing yourself. Write up a spec. Build a schedule. Share these with your management. Hold yourself to deadlines.
Share your concerns with your management; don't be shy about that. Chances are, they recognize the situation. Your boss doesn't check your progress? Publish your progress to him. Show him where you need to get to, how far along you are, and what's blocking you.
It'll be chaotic, no doubt, but you'll learn a lot.
Every organization is different. If they are operating in this capacity then you should adapt and make the best of the situation. It's either happening because that's how things are done and they are aware of it, or they don't know the wiser or don't want to invest to improve the process of delivering strategic/tactical projects.
In a perfect world everyone would have a robust Quality Methodology in place which would provide a framework for Project delivery and systems implementation. It's just not a reality.
Here are some tips to help you operate more effectively:
Identify your sponsors (the people who own the product) and determine the high level benefits and driving objectives of the business problem they seek to solve
Identify your stakeholders (who has influence and who has interest) and get them to communicate their needs as much as possible
Involve both sponsors and stakeholders in the process as much as possible or as much as they want
Capture what requirements you can from them through written form (email)
Provide opportunities for them to gain visibility into the delivery and to provide feedback
Your project will likely fail from your boss point of view. Because i'm sure you developing program not suitable for him. But you don't feel guilty. It's your boss' pain.('because you are good programmer). Sorry for so dark post :-).
The role of the project manager is not to know the technology, but they definitely should have a finger on the pulse of the project, so to speak. The real project management job is not to control the project, but rather to enable it. Either way, from your description, looks like yours isn't doing such a great job at it.
The other extreme is a process-heavy organization where meetings and committees decide everything, and all the real communication, if it exists at all, happens through side channels.
The ideal world lies somewhere in between.
Your project manager should not be too concerned with how you're doing things. Since they have no qualifications, the best they can do is connect you with someone who does. When they can't verify that you're building the thing right, they should at the very least ensure you're building the right thing. Even if it's for internal use, you still have a customer, and no communication with the customer spells bad news to me. :)
If your PM is not concerned about the issue, you could try to do something yourself. For example, ask the PM to connect you with a would-be end user of the application. Extract bits of your application and give them to the user to play with -- just make sure the bits you give them don't look or feel too finished.
If you can't change things, take this as a learning experience. Make sure next time you're up for a project, you know the things that went wrong last time, and try to mitigate them from the start.
And finally, if your bosses tell you this is a "more agile way" of working, punch them in the face. Agile is, or should be, synonymous with discipline, not complete lack thereof.
Good luck!
It is a hard situation. Only you can really determine the best way to proceed. However, I do think that the concern with the schedule and concurrent lack of documentation (requirements, expectations, use-case scenario documentation, etc) is a train-wreck waiting to happen. Even the sharpest and most experienced dev-teams suffer from the same problems.
The "when will it be done?" questions are best mitigated by regularly providing small partially functional builds that you can use to get useful information out of the moving target that is your customer. It is amazing how much communication can occur when somebody (your boss/customer/end-user) can actually "play with" something in front of them and reconsider what they really want.
I believe this situation is quite common. I had this, too, at my previous job. Here the bet is on the fact that you are already independent and well-versed in your business. I think you should tell your manager how you feel about this.
They should change something after hearing your opinion about this situation. Because if you do something wrong and the manager does not notice it, the company can lose a lot of money and time.
But it’s also not worth constantly waiting for someone to guide you and check your work. In any case, your workflow should have self-management.

We have a project hand over from on shore team to our team (off shore) not long ago. However we were having difficulties for the hand-over process.
We couldn't think of any questions to ask during their design walk-through, because we were overwhelmed by the sheer amount of information. We wanted to ask, but we didn't know what to ask. Since they got no question from us, the management think that the hand-over process was been done successfully.
We had tried to go through all the documentation from our company wiki page before attending the handover presentation, but there are too many documents, we don't even know where to start with.
I wonder, are there any rules or best practices that we can follow, to ensure a successful project hand-over, either from us, or to us.
Thanks.
In terms of reading the documentation, personally I'd go for this order:
Get a short overview of the basic function of the application - what is it meant to achieve. The business case is probably the best document which will already exist.
Then the functional specification. At this point you're not trying to understand any sort of how or technology, just what the app is meant to do. If it's massive, ask them what they key business processes are and focus on those.
Then the high level technical overview. This should include an architecture diagram, required platforms, versions, config and so on. List any questions you have.
Then skim any other useful looking technical documents - certainly a FAQ if there is one, test scripts can be good too as they outline detailed "how to" type scenarios. Maybe it's just me but I find reading technical documents before I've seen the system a waste - it's too academic and they're normally shockingly written. It's certainly an area I'd limit the time I spent on if I didn't feel I was getting a reasonable return for the time I was spending.
If there are several of you arrage structured reviews between you and discuss the documents you've read, making sure you've got what you need to out of it. If the system is big then each take an area and present to the others on it - give yourselves a reason to learn as much as possible and knowing you're going to be quizzed is a good motivator. Make a list of questions where you don't understand something. Having structured reviews between you will focus your minds and make it more of an interactive task, rather than just trawling through page after page of tedious document.
Once you get face to face with them:
Start with a full system demo. Ask questions as they come up, don't let them fob you off with unclear answers - if they can't answer something have it written down and task them with getting the answer.
Now get the code checked out and running on your machines. Do this on at least two machines - one they lead, one you lead. Document the whole process - this is the most important step. If you can't get the code running you're screwed.
Go through the build process. Ensure that you can build the app (including any automated build and unit tests they may have). Note that all unit tests should pass - if they don't or if they say "oh, that one always fails" then they need to fix that before final acceptance.
Go through the install process. Do this at least twice, one they lead, once you lead. Make sure that it's documented.
Now come up with a set of common business functions carried out with the application. Use this to walk the code with them. The code base will be too big to cover the whole thing but make sure you cover a representative sample.
If there is a database or an API do a similar exercise. Come up with some standard data you might need to extract or some basic tasks you might need to carry out using the API and spend some time working through these with them.
Ask them if there's anything they think you should know.
Make sure that any questions you've written down anywhere else are answered.
You may consider it worth going through the bug list (open and closed) - start with the high priority ones and talk through anything particularly worrying looking. Even if they've fixed it it may point at a bit of code which is troublesome.
And finally if the opportunity exists - if there are any outstanding bugs or changes, see if you can pair program a couple.
Do not finally accept the app unless you are 100% sure you can:
Get the code to compile
Get the code to build (including the database)
Get the application installed
Do not accept handover is complete until they have:
Documented anything you picked up on that wasn't covered to your satisfaction
Answered ALL of your questions - a question they won't answer after being asked repeatedly screams of something they're hiding
And grab their e-mail addresses and phone numbers. Even if it's only informal they'll probably be willing to help out if the shit really hits the fan...
Good luck.
My basic process for receiving a handover would be:
Get a general overview of the app, document it
Get a list of all future work that the client expects
... all known issues
... any implementation specifics
As much up-to-date documentation they have
If possible, have them write some tests for critical components of the system (or at least get them thoroughly documented)
If there is too much documentation (possible) just confirm that it is all up to date, and make sure you find out from them where to start, if it is not clear.
Ask as many question as possible; anything that comes to mind, because you may not have the chance again.
Most handovers, perhaps all of them, will cause a lot of information to be lost. The only effective way to perform a handover that I have seen is to do it gradually. One way to do it is to allow a few key people from phase One to stay on the project well into Phase Two.
The extreme solution is to get rid of all handovers, and start using an Agile mindset.
As a start, define the exit criteria for the handover. This should be discussed, negotiated and agreed with both parties and make sure higher management knows this. Then write up a checklist of all things needed to achieve the exit criteria and chase it.
Check out "Software Requirements" and Software Requirement Patterns for ideas on questions to ask when gathering information about a project. I think that just as they would work for new development, they would also help you to come to terms with an existing project.

What do you do when you join a team that says they use Scrum, but only use it as a time-management tool and not the whole process?
How can I reinstate back testing and documentation?
I was thinking to start off with adding user stories specifically for testing and documenting.
Perhaps someone else has more experience with this then I do about this as I am sure its not that uncommon.
The key to scrum is that a task be identifiable as "done" before it can be classed as done. How does you company assess whether something is done without reviewing documentation and tests?
Perhaps they have an unusual, but valid, way of doing it. Or perhaps they have missed the point of "done tasks". I'd suggest you start by asking them how they measure down and whether it could be improved. Then suggest documentation and testing as the way of improving the process.
Note that neither testing nor documentation are in fact part of Scrum. Scrum is a pure project management approach - the required engineering practices, like the ones you mention, are supposed to "emerge" during the project. And most specifically, they are supposed to be identified during the heartbeat retrospectives that you do at the end of every sprint. Are you doing those? Can you bring up your concerns there - and are they actually the biggest concerns the team has?
Is the issue that they don't have any documentation and tests, or that they aren't implementing the entire Scrum methodology? Those are 2 very different problems in my mind.
I would much prefer an organization that has taken the time and effort to find and fit a development process that matches their development style as opposed to mandating down from on high the one true process. So I would not be concerned at all if they were using a process that they called Scrum but that didn't meet all the "official" guidelines. Try to determine why the process is the way it is. Chances are that if they have taken the time to tailor it, the team will be receptive to your ideas, especially if you have taken the time to determine why things are the way they are. If you simply approach it as "this isn't Scrum and so isn't right", you will probably not make much headway, but by being pragmatic about the benefits you can likely make some substantial improvements.
Alternatively, if they aren't doing testing and don't have any documentation I would consider that a fairly bad sign. And by documentation I am taking the minimalist view here - a list of features, bug tracking, etc. - I would be very concerned by the absence of these items, less concerned by the absence of items higher up the abstraction list. In the absence of support from management, I would suggest you lead by example. Take it on yourself to setup a simple bug tracking system (there are several - in a pinch, simple text lists in a central location work as well). Don't declare your features complete until someone else has tested it. This can be as simple as walking over to another developer and asking them to try it in front of you. If someone claims a feature is complete, take a few minutes to familiarize yourself with it. If you find a bug, politely mention it to the responsible developer. Slowly build an environment where the team can see the benefits of running tests and tracking features and bugs.
Most teams operate in this manner simply because of a mistaken belief that they don't have time to "do it right", or that they will get to it later. Often this will occur when a simple proof-of-concept done by a developer or two as a side-project turns into a full-on development effort. By showing that it can actually save time and effort, and reducing the initial costs to the rest of the team, you will often find that it becomes ingrained as part of the process without ever actually being officially endorsed or accepted.
If you have management support it will make it much easier, but always be careful to make sure that the team is receptive to the changes. This may mean it takes longer than you want, but so be it, without the team's support any mandated process will fail at the first sign of pressure, which is when you need the process the most.
*Disclaimer - On my last project I spearheaded the movement to tailor the SCRUM process to fit our environment. The "official" process was simply untenable for our client, but it was still an invaluable guide in tailoring our process.
"adding user stories specifically for testing and documenting"
While meta-user stories might make sense in some circles, it rarely works out well. Software folks rarely cope well with meta-user stories, they either don't get the idea that they can change their own processes by writing a story, or -- more typically -- they engineer the meta-user story to death.
When you're interviewing users, it feels like they're making the user story up. Certainly, you're making it up as you listen to them and try to capture it.
When an IT organization tries to make up its own user stories about how IT should work, the process falls apart. Until the organization has done the thing (testing, for example) a bunch of times manually, they're not really qualified to write user stories. Then, after they've done it, they don't need software development processes, they'll just automate the important bits a little at a time.
I think change has to come from a less formal direction. Actually balking at calling something "done" that hasn't been tested is a good starting point.
IT doesn't do things unless forced. So, meet the users and find out why they're not requiring testing. Coach them to require testing. Tell them the consequences and the words to use.
A lot can go wrong in an organization to lead to poor processes. It's important to know what's wrong, and create a demand for change. The best possible thing is to have your boss complaining that you're not fixing it, rather than you suggesting that perhaps it would be good to fix it.
[It doesn't feel right when your boss demands you fix the process, but it's about the only way change will happen.]

One of our developers is continually writing code and putting it into version control without testing it. The quality of our code is suffering as a result.
Besides getting rid of the developer, how can I solve this problem?
EDIT
I have talked to him about it number of times and even given him written warning
If you can do code reviews -- that's a perfect place to catch it.
We require reviews prior to merging to iteration trunk, so typically everything is caught then.
If you systematically perform code reviews before allowing a developer to commit the code, well, your problem is mostly solved. But this doesn't seem to be your case, so this is what I recommend:
Talk to the developer. Discuss the consequences for others in the team. Most developers want to be recognized by their peer, so this might be enough. Also point out it is much easier to fix bugs in the code that's fresh in your mind than weeks-old code. This part makes sense if you have some form of code owneship in place.
If this doesn't work after some time, try to put in place a policy that will make commiting buggy code unpleasant for the author. One popular way is to make the person who broke the build responsible for the chores of creating the next one. If your build process is fully automated, look for another menial task to take care of instead. This approach has the added benefit of not pinpointing anyone in particular, making it more acceptable for everybody.
Use disciplinary measures. Depending on the size of your team and of your company, those can take many forms.
Fire the developer. There is a cost associated with keeping bad apples. When you get this far, the developer doesn't care about his fellow developers, and you've got a people problem on your hands already. If the work environment becomes poisoned, you might lose far more - productivity-wise and people-wise - than this single bad developer.
As a developer who rarely tests his own code, I can tell you the one thing that's made me slowly shift my behavior...
Visibility
If the environment allows pushing code out, waiting for users to find problems, and then essentially asking "How about now?" after making a change to the code, there's no real incentive to test your own stuff.
Code reviews and collaboration encourage you to work towards making a quality product much more than if you were just delivering 'Widget X' while your coworkers work on 'Widget Y' and 'Widget Z'
The more visible your work is, the more likely you are to care about how well it works.
Code review. Stick all of your dev's in a room every Monday morning and ask them to bring their most proud code-based accomplishment from the previous week along with them to the meeting.
Let them take the spotlight and get excited about explaining what they did. Have them bring copies of the code so other dev's can see what they're talking about.
We started this process a few months ago, and it's astonishing to see the amount of sub-conscious quality checks that take place. After all, if the dev's are simply asked to talk about what they're most excited about, they'll be totally stoked to show people their code. Then, other dev's will see the quality errors and publicly discuss why they're wrong and how the code should really be written instead.
If this doesn't get your dev to write quality code, he's probably not a good fit for your team.
Make it part of his Annual Review objectives. If he doesn't achieve it, no pay rise.
Sometimes though you do just have to accept that someone is just not right for your team/environment, it should be a last resort and can be tough to handle but if you have exhausted all other options it may be the best thing in the long run.
Tell the developer you would like to see a change in their practices within 2 weeks or you will begin your company's disciplinary procedure. Offer as much help and assistance as you can, but if you can't change this person, he's not right for your company.
Using Cruise Control or a similar tool, you can make checkins automatically trigger a build and unit tests. You would still need to ensure that there are unit tests for any new functionality he adds, which you can do by looking at his checkins.
However, this is a human problem, so a technical solution can only go so far.
Why not just talk to him? He probably won't actually bite you.
Make him "babysit" the build, and become the build manager. This will give him less time to develop code (thus increasing everyone's performance) and teach him why a good build is so necessary.
Enforce test cases - code cannot be submitted without unit test cases. Modify the build system so that if the test cases don't compile and run correctly, or don't exist, then the entire task checkin is denied.
-Adam
Publish stats on test code coverage per developer, this would be after talking to him.
Here are some ideas from a sea shanty.
Intro
What shall we do with a drunken sailor, (3×)
Early in the morning?
Chorus
Wey–hey and up she rises, (3×)
Early in the morning!
Verses
Stick him in a bag and beat him senseless, (3×)
Early in the morning!
Put him in the longboat till he’s sober, (3×)
Early in the morning!
etc. Replace "drunken sailor" with a "sloppy developer".
Depending on the type of version control system you are using you could set up check-in policies that force the code to pass certain requirements before being allowed to check-in. If you are using a sytem like Team Foundation Server it gives you the ability to specify code-coverage and unit testing requirements for check-ins.
You know, this is a perfect opportunity to avoid singling him out (though I agree you need to talk with him) and implement a Test-first process in-house. If the rules aren't clear and the expectations are known to all, I've found that what you describe isn't all that uncommon. I find that doing the test-first development scheme works well for me and improves the code quality.
They may be overly focused on speed rather than quality.
This can tempt some people into rushing through issues to clear their list and see what comes back in bug reports later.
To rectify this balance:
assign only a couple of items at a time in your issue tracking system,
code review and test anything they have "completed" as soon as possible so it will be back with them immediately if there are any problems
talk to them about your expectations about how long an item will take to do properly
Peer programming is another possibility. If he is with another skilled developer on the team who dies meet quality standards and knows procedure then this has a few benifits:
With an experienced developer over his shoulder he will learn what is expected of him and see the difference between his code and code that meets expectations
The other developer can enforce a test first policy: not allowing code to be written until tests have been written for it
Similarly, the other developer can verify that the code is up to standard before it is checked-in reduicing the nmber of bad check-ins
All of this of course requires the company and developers to be receptive to this process which they may not be.
It seems that people have come up with a lot of imaginative and devious answers to this problem. But the fact is that this isn't a game. Devising elaborate peer pressure systems to "name and shame" him is not going to get to the root of the problem, ie. why is he not writing tests?
I think you should be direct. I know you say that you've talked to him, but have you tried to find out why he isn't writing tests? Clearly at this point he knows that he should be, so surely there must be some reason why he isn't doing what he's been told to do. Is it laziness? Procrastination? Programmers are famous for their egos and strong opinions - perhaps he's convinced for some reason that testing is a waste of time, or that his code is always perfect and doesn't need testing. If he's an immature programmer, he might not fully understand the implications of his actions. If he's "too mature" he might be too set in his ways. Whatever the reason, address it.
If it does come down to a matter of opinion, you need to make him understand that he needs to set his own personal opinion aside and just follow the rules. Make it clear that if he can't be trusted to follow the rules then he will be replaced. If he still doesn't, do just that.
One last thing - document all of your discussions along with any problems that occur as a result of his changes. If it comes to the worst you may be forced to justify your decisions, in which case, having documentary evidence will surely be invaluable.
Stick him on his own development branch, and only bring his stuff into the trunk when you know it's thoroughly tested. This might be a place where a distributed source control management tool like GIT or Mercurial would excel. Although with the increased branching/merging support in SVN, you might not have too much trouble managing it.
EDIT
This is only if you can't get rid of him or get him to change his ways. If you simply can't get this behaviour to stop (by changing or firing), then the best you can do is buffer the rest of the team from the bad effects of his coding.
If you are at a place where you can affect the policies, make some changes. Do code reviews before check ins and make testing part of the development cycle.
It seems pretty simple. Make it a requirement and if he can't do it, replace him. Why would you keep him?
I usually don't advocate this unless all else fails...
Sometimes, a publicly-displayed chart of bug-count-by-developer can apply enough peer pressure to get favorable results.
Try the Carrot, make it a fun game.
E.g The Continuous Integration Game plugin for Hudson
http://wiki.hudson-ci.org/display/HUDSON/The+Continuous+Integration+Game+plugin
Put your developers on branches of your code, based on some logic like, per feature, per bug fix, per dev team, whatever. Then bad check-ins are isolated to those branches. When it comes time to do a build, merge to a testing branch, find problems, resolve, and then merge your release back to a main branch.
Or remove commit rights for that developer and have them send their code to a younger developer for review and testing before it can be committed. That might motivate a change in procedure.
You could put together a report with errors found in the code with the name of the programmer that was responsible for that piece of software.
If he's a reasonable person, discuss the report with him.
If he cares for his "reputation" publish the report regularly and make it available to all his peers.
If he only listens to the "authority", do the report and escalate the issue to his manager.
Anyway, I've seen often that when people are made aware of how bad they seem from outside, they change their behaviour.
Hey this reminds me of something I read on xkcd :)
Are you referring to writing automated unit test or manually unit testing prior to check-in?
If your shop does not write automated tests then his checking in of code that does not work is reckless. Is it impacting the team? Do you have a formalized QA department?
If you are all creating automated unit tests then I would suggest that part of your code review process include the unit tests as well. It will become obvious that the code is not acceptable per your standards during your review.
Your question is rather broad but I hope I provided some direction.
I would agree with Phil that the first step is to individually talk to him and explain the importance of quality. Poor quality can often be linked to the culture of the team, department and company.
Make executed test cases one of the deliverables before something is considered "done."
If you don't have executed test cases, then the work is not complete, and if the deadline passes before you have the documented test case execution, then he has not delivered on time, and the consequences would be the same as if he had not completed the development.
If your company's culture would not allow for this, and it values speed over accuracy, then that's probably the root of the problem, and the developer is simply responding to the incentives that are in place -- he is being rewarded for doing a lot of things half-assed rather than fewer things correctly.
Make the person clean latrines. Worked in the Army. And if you work in a group with individuals who eat a lot of Indian food, it wont take long for them to fall in line.
But that's just me...
Every time a developer checks something in that does not compile, put some money in a jar. You'll think twice before checking in then.
Unfortunately if you have already spoken to him many times and given him written warnings I would say it is about time to eliminate him from the team.
You might find some helpful answers here: How to make junior programmers write tests?
I'd be tempted to suggest elaborating a bit on what you've tried and what results you got as this may have changed a bit but here are my initial suggestions:
Is it any tests or comprehensive tests? Some may code blindly and do zero tests, but this is rather rare, IME. Usually there are some tests done but not enough to cover most of the cases that would be comprehensive testing.
Group dynamics may help. I'd assume he is part of a team and that the team's view may be of some help here. In a way this is trying to get peer pressure which is usually a bad thing but sometimes it can be used in good ways.
How well spelled out were the warnings? In a way this can seem childish but there is a chance that what you think of as testing may not be the same as his. Do you want nUnit tests, an excel spreadsheet, logs from his computer, or something else as proof of the existence and use of tests? From what you've described there isn't anything to confirm that he did understand what you meant, was going to use tests and provide evidence of doing so.
Check-in policy question. Some places, such as my current workplace, encourage committing often which can mean that one does commit code without tests. Is there a known, accepted and well-followed policy where you are? That's another aspect here.

We're neck deep in a project right now, schedules are tight (but reasonable). Our general strategy is to get a strong beta done, release it for testing, and get feedback from our testers.
Quite frequently, we're being hit by small things that spiral into long, time-costing discussions. They all boil down to one thing: While we know what features we need, we are having trouble with the little details, things like 'where should this message go' and 'do they need this feedback immediately, or will it break their flow, so we should hold off'?
These are all things that our testers SHOULD catch, but
a) Each 'low priority' bug like this drains time from critical issues
b) We want to have as strong a product as possible
and
c) Even the best testing group will miss things from time to time.
We use our product, and we know how our users use the old version...but we're all at a loss as to how to think like a user when we try to use the new version (which has significant graphical as well as underlying changes).
edit - a bit more background:
We're writing a web app used by a widely-distributed base of users. Our app is a big part of their jobs, but not the biggest (and, of course, we only matter to them when it doesn't work). Getting actual users in to use our product is difficult, as we're geographically distant from the nearest location that serves as an end user (We're in Ohio, and I think the nearest location we serve is 3+ hours away).
The closest we can get is our Customer Service team (who have been a big help, really) but they don't really think like the users either. They also serve as our testers (it really motivates them to find bugs when they know that any they DON'T find may mean a big upswing in number of calls). We've had three (of about 12 total) customer service reps back here most of the week doing some preliminary testing...they've gotten involved in the discussions as well.
Watching someone using the app is a huge benefit to me. Possibly someone who is not entirely familiar with it.
Seeing how they try to navigate, how they try to enter information or size windows. Things we take for granted after creating/running the app hour after hour, day after day.
Users will always try and do things you never expected and watching them in action might bring to light how you can change something that might have seemed minor, but really makes a big impact on them.
Read Don't make me think.
Speaking generally, you can't. There's not any way you can turn off the "programmer" part of your brain and think like a user.
And you're right about (c), testing groups don't necessarily catch all the bugs. But the best thing you can do is get a testing group comprised of real, honest-to-goodness end users, and value their feedback. Draw further conclusions from their general comments.
If you want to know how your users will see your system, the closest you can get is usability testing with real users. Everything else is just heuristics and experience, and is also subject to error. There's no such thing as a bug-free product, but you should be able to get a "strong" product with usability testing.
Buy a cheap, easy to use video camera and record your testers using the app. Even better, get some people unfamiliar with the app. to use it and video them. It's relatively cheap, and you'd be surprised what it will highlight.
I like policy of "eating your own dog food"("http://en.wikipedia.org/wiki/Eat_one's_own_dog_food). It brings you one step closer, because you become a user, although you might think like one.
Try to use your app when you are very hurry (e.g. you have someone who waits for a dinner).
You will see all this little things because you have to wait, you have to go back to the mouse of the keyboard, etc.
And also, make your wife use it. Or your mother.
Another useful test : help someone to use it, by phone. If he can't find the button with your directions, that's probably a bug.
The important thing is to get enough information that you yourself can become a "user". Once you do that you can answer most questions yourself.
The way I always do this is to go talk with them about what they need to do, what they typically do, and how they use their current tools to do it. Then (very important) sit with them while they do it. Make sure you get on with them well enough that you can come back to them with questions about how they handle edge cases you think of later (often the answer will be the appalling "we go around the system manually for that").
I will almost always notice something they are doing that is a royal PITA that they didn't bring up because they are used to having to do that and don't know any better. I will always notice that their %90 typical workflow isn't the easiest workflow the tools provide.
You can't really rely on plain old-fashioned requirements gathering by itself, because that is asking them to think like a developer. They generally don't know what is possible to do with your software, what is easy, and what is hard. Also they typically have no clue on GUI design principles. If you ask them for design input they will just tell you to put any new control on their favorite page, until the thing looks like a 747 control panel.
The problem is often that even the users don't know what they want until they are actually working with the software. Sometimes, a small oversight can be a big usability problem, sometimes a well thought out function that was requested by many users sees only little use.
My suggestions to decrease the risk of not implementing the right usability features:
Take a look at users actually doing their day to day work. Even if they use another software or no software at all. You will be able to determine the artifacts they often need to get their job done. You will see what data they frequently need. Concentrate on the artifacts, data and workflows most used. They should be the most usable. Exotic workflows may be a bit more time consuming for the users than often used workflows.
Use working prototypes of the GUI to let users work through a realistic workflow. Watch them and note what hinders them and what works well. Adjust your prototypes accordingly.
If an issue arises in an often-used part of your software, it is time to discuss it now and in details. If the issue concerns a seldom used part, make it a low priority issue and discuss it if you have the time. If issues or suggestions are low priority, they should stay low priority. If you can't determine if solution A or solution B is the best, don't run in circles with the same arguments over and over. Just implement one of the solutions and see if the beta testers like it. The worst thing you could do is waste time over tiny issues, while big issues need to be fixed.
A software will never be perfect, because the viewpoints of users differ. Some users will think that a minor problem breaks the whole application. Others will live with even severe usability issues. People tend to lend their ear to those who argue the loudest. Get to know your users to separate the "loud" issues from the important ones. It takes experience to do this, and sometimes you will make wrong decisions, but there is no perfect way, only one of steady improvement.
If you can, set aside a certain amount of usability development resources for the rollout phase of your software. Usability issues will arise when people start working with it in a real production environment. Sometimes it is not important to present the perfect software, but to solve issues quickly as they arise.
The flippant (yet somewhat accurate) answer to how to think like a user is put a knitting needle in your ear and push really hard.
The longer response is that we as programmers are not normal and I mean that in a good way. I scratch my head at the number of people who still run executables they receive from strangers in emails and then wonder how their computer got infected.
Any group of people will in time develop their own jargon, conventions, practices and expectations. As a programmer you will expect different things from an operating system than Joe User will. This is natural, to be expected yet hard to work around.
It's also why BAs (business analysts) exist. They typically come from a business or testing background and don't think like programmers. They are your link to the users.
Really though, you should be talking to your users. There's no poitn debating what users do. Just drag a few in and see what they do.
A usability test group will help.. tests not focused on discovering bugs, but on the learning curve of the new design, made by a group of users, not programmers.
I treat all users like malicious idiots.
Malicious because I assume all users are going to try and break my code, do stuff that is not allowed, avoid typing in valid data, and will do anything in their power to make my life hell.
Idiots because again I can't assume they will understand simple stuff like phone formats, will run away screaming if presented to many choices, and will not make any leap of faith on complicated instructions. The goal is to hold their hand the entire way.
At the same time, its important to make sure the user doesn't realize you think they're an idiot.
To think like a user, be one. But are these actually bugs that your testers are reporting? Or are they "enhancement requests"? If the software behaves as designed per requirements and they just don't like the way it operates, that's not a bug. That's a failure of requirements and design. Make it work, make it rock solid, make it easy to change and you'll be able to make it what your users want.
I see some good suggestions here, especially observing people trying to use you app. One thing I would suggest is to look at the order in which things are presented to the user on paper forms (if they use these to do data entry from) and make the final data entry page mimic that order as closely as possible. So many data entry errors (and loss of data entry speed) are from them having to jump around on the page and losing their place. I did some work for a political campaign this year and in every case, entering data was made much more difficult because the computer screen did things in a differnt order than the paper inputs. This is particularly important if the form is one that can't be changed (like a voter registration form, a campaign has to use what the state provides) to match the computer screen. ALso be consistent from screen to screen if possible. If it is first Name last name on one form, making it last name first name on the next will confuse people and guanteee data entry errors.
If you are truly interested in understanding users though I strongly suggest taking a course in Human factors engineering. It is an enlightening experience.
The 'right' way to do this is to prototype (or mock up) your new interface features, and watch your users try to use them. Nothing is as enlightening as seeing a real user try to use a new feature.
Unfortunately, given most projects time and resources, this is not possible. If that is the position you are in I would recommend you discuss in the team who has the best grasp of usability, and then make them responsible for usability decisions - but that person will need to regularly consult real users to make sure his/her ideas are consistent with what the users want.
I'd suggest doing some form of usability testing; I've participated in such in the past, and found them quite useful.
If you were writing a ticketing system, for example, bring up tasks, and ask questions like "how would you update this ticket" or "what do you expect to happen if this button is clicked".
You don't necessarily need a full application, either, in some places screen shots can be used.
You could take the TDD/BDD approach and get the users involved before beta, having them work with you on refining requirements as you write your unit tests. We're beginning to incorporate some of those trends into our current project, and we're seeing fewer bugs in the areas where we have involved the users earlier.
There is no "think like a user" technique, get your hands on someone who knows nothing of the project and throw what you have done at them.
It's the only way to see how the look + feel + functionality present themselves to the end user.
Once you shocked that person who knew nothing of the product, listen to all of their idiotic (or so you think they are) complaints, fix them, arrange every silly cosmetic thing they point out (either by fixing the UI or by improving whichever documentation you had)..
and after you have satisfied the person you chose to look at your app from zero knowledge on the subject first round, pick another ...and another... until they stop being shocked when they see it, and they don't get stuck on.. "ok.. what does this do?" kind of phases.
You (as a member of the project, be it the project manager, developer, etc) will never think like a user is my answer to that question.
Old saying: You can make something "fool proof" but you can't make it "Damn-fool proof".
Additionally: When you make something "idiot proof" the world invents a better idiot.
Other than that, I agree with what everyone else said.
Ask someone with absolutely no knowledge, insight or programming experience to use the program and try to figure out every function of the program.
People who would NEVER use such a program are most likely to find bugs.
See it as a new Safari user (or FF) who tries to put the URL inside the search field...
As a programmer you guess no-one would be that stupid (or, well.. unknowing), but people actually sometimes find themselves in these situations. As a programmer, we miss these things.
