Re: [epf-dev] OpenUP Summary Graphic

[Mark.Dickson@xxxxxxxxx]

My 2cents

I talked through this diagram with someone new to OpenUP recently and the gears idea really worked for them. The concept that actual work pushes the project through the phase milestones rather than the team being pushed through an arbitrary phase plan seemed to work well in discussion.
I agree with the idea that the micro-increment should have a build product associated with it. What we label it is open for discussion but it should be distinguished from a "shippable build".
During discussion (and not for the first time) I found myself flipping back to the classic RUP humpback diagram to emphasise that there is activity from many disciplines in a phase increment - the old "iterative not waterfall" discussion still lives :-). I seem to recall a discussion about dropping this approach from our graphic but this may have created a gap in the message.
Overall though, the response to the graphic has been vet positive, in my experience.
Cheers

A few thoughts
1. The gears are a bit distracting.  We should clean them up.
2. Each of the rows should produce something.  i.e. the daily cycle
results in a working build.  This would help to get the idea across that
working software is a major deliverable.
