Formal
procedures for Release Management are not covered. This area also focuses on having
a formal change request process in place.
Things that most organizations tend to forget about this process area:
There are several different types of baselines. There can be formal baselines
that have been formally agreed to by a formal group, as well as informal baselines.
Informal baselines are what the original CMM for Software referred to
as Developmental baselines. Basically, in Developmental baselines, two programmers
are assigned to update the same program or piece of code. In this
case, one programmer agrees with the other programmer to wait to make his
fix until the other guy has completed his fix, tested it, and uploaded it into
Production. That way, both fixes get loaded correctly. Without this informal
agreement, only the last fix would get loaded into Production. The first fix
made the first programmer would have been overwritten by the fix completed
by the second programmer. The organization needs to define when each type
of baseline (formal or developmental) should be used.
