The power of negative…

No, I don’t mean a negative attitude because although that feels great sometimes, I don’t think it is a particularly powerful way of accomplishing anything :). What I mean is “negative questions”, i.e. “what can you do without?”, “what should this not do?” etc.

Usually when developing requirements, the business stakeholder/sponsor has no incentive to remove any requirements, which either means you get a bloated list that isn’t realistic or you get to play the bad guy when you have to explain why the pitiful budget that was allocated does not cover the whole list of requirements. And sometimes both…

Even with an unlimited budget, asking what the requester can do without force thoughts about real needs and priorities, thus helping drive the really important discussions and tease out valuable information. In many of these situations you can “opt-in” on everything without any real cost and involvement, but you can’t “opt-out” of anything without considering the consequences first and that’s what the architect needs to take advantage of.

People are normally a bit taken aback when you ask them what a certain system/process should not do, but the answers are usually worth it – especially if they are open about their rationale for saying no. Try this technique and you may be surprised at the results as well.
