Look for the pain
To start modelling any system, process or architecture, look for the pain points. Don’t model stuff just because you think it ‘might help’
- If your project has an issue with duplication of effort, then make sure your modelling approach deals with overlaps and re-use of ideas.
- If it’s managing changes, show how you can do that. Fast impact analysis, quick turnaround of new deliverables looks important.
- If it’s encouraging your stakeholders to engage with the project, then concise, customized documents or website access will be important.
Address these from the start, not as an afterthought. Thinking about these objectives will focus your modelling efforts, and you may end up doing less work than you thought.
