I think the time to document should also be included when deadlines are being drawn. Documentation is always a good thing and it is not only for the next programmer or your PM. Why? Because of all the phases in the software development life cycle the maintenance phase is the biggest and if you don't document your own code how will you know what you were thinking when you wrote it?

Typically, I write my code specifically to be self-documenting. If I absolutely must do something that looks strange, I make sure to comment it well. Other than that, names for variables, functions, etc should make their purpose self-explanatory.

Theoretically, this is true. However, Documentation is different than self-explanatory code in that documentation documents intent, code is functionality. When intent and functionality match, generally you have at least bug-free code. When code is used against its intent, or intent and functionality do not match (unwanted side-effects, or just not quite doing what you wanted it to do), you have bugs. Although I am a firm supporter of self-explanatory code, I still want the documentation, if only to document intent. Debugging can be shortened significantly by comparing intent with functionality. Otherwise how do I know you didn't intend to share a global value that inhibits reentrant behavior?

I expect my requirements documents to do that. I learned the hard way not to start coding a damn thing until you have completed the requirements gathering phase of development (which managers want to do least since it is generally where they are the ones doing most of the work). As developers, it is important to not let your manager/requirements analyst to skate by doing little to nothing while putting all the pressure/blame on you to implement crazy code. With proper requirements documents and readable code, there is no need to document code afterwards, and in fact, doing so would likely cause maintenence headaches later since the code is likely to be changed slightly and would require the documentation to be updated accordingly.

Set a baseline for the rules you will implement and implement them. If you keep trying to chase a moving target, your project will fail. If they want more rules to be implemented, tell them to submit it for the next revision of the product. The one thing that many developers don't learn is the ability to say "No", and "Not now". If you give in to managers/customers who change requirements on a whim, you never get anything shipped and end up losing lots of money.

I'm curious why the developer(s) would need to make the distinction between coding and documenting. They should be one in the same. Asking a manager to do anything but produce "code" is just a recipe for a big no.

Performance / apprisal all depends on it. Manager has to think before involving with more engagement than wrapping up things. We tried to convince but manager is the boss! -

This is where you are wrong. If your manager keeps asking for unreasonable requirements (e.g. no documented requirements or constantly changing requirements), he is a poor manager. You can go about it several ways: talk to them about creating firm requirements for the project, talk to their boss about having firm requirements established (and possibly your boss' lack of desire for such), request a transfer to another division within your company, or simply find a new job. Firms that have too many managers that behave like this don't tend to stay in business long anyway.

This is when you need to suggest a requirements analyst be added to the team. Their job being to gather, document, and either accept or reject a set of requirements for each revision (and give a reason for rejection) of a product. Typically, managers try to do this, but if they are failing at it (either by choice or simply because of lack of knowledge), it is time to fix the process.

That's a start but it may not indicate things like: 1) Why it is needed 2) Why the path or technique was selected 3) Why other path(s) were not selected. 4) Pre-conditions 5) Post-conditions 6) Exceptions that may be thrown ...... etc.

All that should be in the requirements documents. That is, written before coding has been started (granted, prototypes may have been written, but no production code yet).

How do you document a methods pre and post conditions in a requirements document written "before" the method exists? :confused:

Requirements documentation is vastly different from code documentation.

I would highly disagree with this point. Readable, self-documenting code does not take the place of well documented code.

It is amazing beyond belief to me that anyone would not do at least minimal architecture and minimal documentation, regardless of time/money crunch realities. Because that minimal effort will SAVE YOU TIME. I'm preaching to the choir, I know. Unfortunately, the choir is not employeed by the majority of companies and clients I've worked for. Marc

Its not perfect, but it is far better than where I was at before (like I said, I learned tha hard way that chasing moving targets ALWAYS leads to failed projects). But I work for a defense contract that does modeling and simulation work.
