Unfortunately, some decisions are hard to change, like database schemas.
Even if you have some migration in place, with large amount of data it
can be an arduous task.
So, in some cases, I think it's interesting to release in batches so you
can postpone this kind of decision to the last responsible moment.

You have to get the business to accept to use the release. I am involved in a Wiki \
that focuses on the strategic part. The aim is to collect patterns and principles \
that make it possible to release often:<br> ><br>
