|Re: [epf-dev] Lifecycle diagram revision|
I am a Ph.D student at Portland State
University. I have
been monitoring EPF project for a while. I am actually not a committer
but I am studying the developer material at this moment. My research area
is Software Process and Metrics. I have read a lot about RUP and Agile
methodology. Attached are some ideas that I have regarding the life cycle
model. I borrow the idea from the RUP iterative diagram. I think it
helped me when I present to other students.
The OpenUP1 is a bit cleaner. It has inner circle as iterative diagram and the outer circle as the OpenUP Phases. The size of each phase are different. I try to convey the growth of work products.
The OpenUP2 provide the view of work product growth. I like Ana's idea about that. However, people could interpret the larger of boxes as effort or duration for each phase, which is not quite correct. That's why I have arrow called "Work Product".
The diagrams and
color are not set in stone. I just like
to convey my idea. I hope that the digrams are not too far off from what you have in mind.
There is an interesting analogy that I had when I think about the OpenUP2. We can view the iteration circle as a wheel that tries to climb the slope to the finish line. For each phase, we could put the milestones that need to be accomplished.
I like the last one as it shows the product getting "bigger" and more
complete through the four phases.
Regarding the lifecycle diagram, attached is a slide that appears in APG's
RUP training that might foot the bill. The things I like about it is it
shows "loopy" iterations occuring continually throughout the phases, makes
some distinction between the end of a phase and the end of a "normal"
iteration, and provides descriptive labels related to the problem and
solution for each phase.
Regarding the presumed inclusion of Daily Meetings (which certainly isn't a
bad idea), I'm sure everyone noticed the numerous Bugzilla entries for
incorporating XP content. I was wondering (like Brian and perhaps others),
if we had made a decision to include the XP content into the "core"
OpenUP/Basic 1.0 content. I guess I thought (perhaps naively, for no good
reason) that it was going to be an extension to OpenUP as a plug in someway
I think discussing the entry/exit state thing would be pertinent...

I think the first one is a great picture and we should find a place for it.
On the other hand the "lifecycle diagram" (that started this
thread) is the picture above the WBS that is labeled Workflow on the
Lifecycle page. I think this diverges too much from the focus of "what is
the lifecycle?" and instead covers "what's it all about?" Especially the
ones without the phases.
I like the picture though. A lot. Perhaps this is a missing graphic at the
top of the Core Principles page.
Did we add Daily Meetings as a definitive, default characteristic of
Back to the lifecycle diagram, I think it can have iterations added somehow.
Perhaps just in a more aesthetically pleasing version of what Steve scrawled
or perhaps someone has a more innovative representation.
Though the Lifecycle page does not call it out, WBS elements are understood
to have Work Product Usage in addition to the task-centric perspective. I'd
love for us to get the focus on the ever growing product in there (as
suggested by Scott). Of course we don't have a Work Product called Product,
just the Build. Maybe something like Ana's ever-growing blocks could fit
into the Lifecycle Diagram.
BTW, do we need a side discussion on the Entry State and Exit State and
Deliverable columns on the Work Product Usage? That sounds like something
that could add a little more clarity to the process.

just some ideas ... modified from a picture I saw for something else...
.. I tried to show core principles, some practices inside the iteration and
the phases ... maybe its too much
