If you’re going to successfully fire up your micro-ISV, you need to fire your old ideas about software development, be they UML, RUP, agile, SCRUM, extreme or none: they fit like shoes on fish.
Every single methodology for developing software I’ve heard of in over 20 years in this business assumes you’re part of some vast team of programmers, never a programmer working alone. What’s more, each and every existing software development process assumes someone is going to hand you a nice gift-wrapped definition of the problem you’re going to solve via code. That is exactly what won’t happen when it comes to developing a micro-ISV app or web site.
Today’s software design theories are like using a power drill as an ear cleaner - they can be used, but it’s not a good idea. We need a better approach, one based in the reality of one or maybe two programmers who must also define the problem and its solution and who want to do so before their savings run out.
Don’t underestimate just how hard defining the problem domain is, or just how difficult it is to nail down in the absence of actual customers who will tell you what they want. Unless you plan to take a few years unpaid leave from your life to do intensive market research, endless focus groups and surveys, at best you are only going to have a very approximate idea of who is going to be using your software how to solve exactly which problem in what precise way at least all the way through to your public beta.
