The recurring thought I have is that we are pressing on with design -
architecture, info-model etc - and have not, AFAIK, agreed requirements,
which the use cases should do, or at least bring out into the open.  So
I would oppose the adoption of any design document until the
requirements have greater clarity.

Your comment about boiling oceans I see rather as boiling separate
lakes, each lake being firmly founded on a different view of use cases,
and I think that that has emerged in the discussion of the info-model.

So, for me, use cases comes first, one document preferred, more than one
ok; the rest should wait.
