It looks like I need to put a little more work into Logical Design, I’ve realised now that defining scope can occur several times, as the analysis and design refine the problem and the solution. After analysis the decision needs to be made of ‘how much’ of the problem needs to be solved, which comes down to the process model and detemining the Use Cases. I’m trying out some new blogging software BlogDesk, which seems to be doing the job, so far, soo good.
