Functional Specs (long and getting longer) [signed]

There has always been a sense about web development that everything must be
new and other disciplines have nothing to add to what we are doing.
Particularly since web development has been done in a hurry. Remember that
old adage that Internet time was like dog years...
My view of the FS is that of a blueprint: you would never invest the
millions of dollars needed to build a bridge or a building without knowing
exactly what was required. Web development, interaction, digital, rich media
(whatever it is we do) design has to be done to the same or similar
standard. We have been lucky since most people don't know what it is we do
and if necessary we can bullshit them out of our office: but that is a
The FS is the blueprint for everyone involved in the project: the wacky
marketing people, the odd IT folks, and the receptionist. Just like a
blueprint it explains what we what to do and what we have to do. It gives us
criteria to show the completed project as completed. It helps us control the
The particular scope that I worry most about comes not from the client,
which I can manage, but from programmers. It is the programmer working alone
who comes to a decision point and says "I think this works better so I am
going to add this feature" that scares me the most. So I want a good FS that
everyone understands there to guide that person and everyone else involved
in the project. There is a lot of creativity that goes into writing the
specification: there is no creativity (or very little) in following it.
In general parlance: a bad FS is better than none. So without a strong
standard what do we do? The best thing is to review and debrief projects
after they are done. In order to do that we need to document them well
beyond what we *want* to do. As well it can be difficult to find the time to
talk about old projects but without this process we don't have enough
information to improve the next project.
