What are the Type of CMM Levels, Explain Each Level.

Answer Posted / manohar

Level 1 - Ad hoc (Chaotic) : It is characteristic of
processes at this level that they are (typically)
undocumented and in a state of dynamic change, tending to
be driven in an ad hoc, uncontrolled and reactive manner by
users or events. This provides a chaotic or unstable
environment for the processes.
Level 2 - Repeatable : It is characteristic of processes
at this level that some processes are repeatable, possibly
with consistent results.
Process discipline is unlikely to be rigorous, but where it
exists it may help to ensure that existing processes are
maintained during times of stress.
Level 3 - Defined : It is characteristic of processes at
this level that there are sets of defined and documented
standard processes established and subject to some degree
of improvement over time. These standard processes are in
place (i.e., they are the AS-IS processes) and used to
establish consistency of process performance across the
organization
Level 4 - Managed : It is characteristic of processes at
this level that, using process metrics, management can
effectively control the AS-IS process (e.g., for software
development ). In particular, management can identify ways
to adjust and adapt the process to particular projects
without measurable losses of quality or deviations from
specifications. Process Capability is established from this
level.
Level 5 - Optimized : It is characteristic of processes at
this level that the focus is on continually improving
process performance through both incremental and innovative
technological changes/improvements.
