Re: [AM] Agile Data Warehouse

The code is not degenerating, but it is hardly optimal. One of the big
issues we are having is cleaning up our learning messes, including
reconciling a couple of deeply felt design philosophies (we really don't
want to get into competing DW dogma here.)

We are restructuring is some places and hiding the differences through
our query tool in others.

an idea of what you might be able to do for them.  Sounds good.

Okay, going at the big picture in a piecemeal fashion will 
expose you to the need for more change than going at it BDUF,
so you need to make change cheap.  OTOH, if you go BDUF
and get anything wrong, the cost of change is horrendous.
If you managed to achieve results, sounds like you made the
right choice.  How's the quality of code?  Is it degenerating, or
are you managing to keep it fresh?  What about the structure
of the data?  Is that holding up well?  If both of these look
good, congratulations, award yourselves a gold star  ;-)

That sounds like a good way to go.  Do things when they
get high enough priority; do something else if that is more
important.  Beware of keeping switching contexts, though.
You probably only want to consider switching 'projects'
at the end of an iteration - emergencies excepted.
