The “functional view”

This is similar to the previous diagram and is very common, particularly in large organisations for some reason.

Essentially the group that produced this diagram has simply documented their functional decomposition of the solution into things, which I again assume are components, services, modules, etc but I could be wrong. Imagine a building architect drawing you a diagram of your new house that simply had a collection of boxes labelled “Cooking”, “Eating”, “Sleeping”, “Relaxing”, etc.

This diagram suffers from the same problem as the previous diagram (no responsibilities and no interactions) plus we additionally have a colour coding to decipher. Can you work out what the colour coding means? Is it related to input vs output functions? Or perhaps it’s business vs infrastructure? Existing vs new? Buy vs build? Or maybe different people simply had different colour pens! Who knows. I often get asked why the central “Risk Assessment Processor” box has a noticeably thicker border than the other boxes. I honestly don’t know, but I suspect it’s simply because the marker pen was held at a different angle.
