Capability Maturity Model Integrated

• Capability Maturity Model:
A reference model of mature practices in a specified discipline, used to
assess a group’s capability to perform that discipline
• CMMs differ by
– Discipline (software, systems, acquisition, etc.)
– Structure (staged versus continuous)
– How Maturity is Defined (process improvement path)
– How Capability is Defined (institutionalization)
• “Capability Maturity Model®” and CMM® are used by the Software
Engineering Institute (SEI) to denote a particular class of maturity models

• Systems and software disciplines
have traditionally not been well
integrated
• The importance of software in
systems has increased dramatically
– Example: % of requirements
allocated to software: *
• B-2 -- 65%
• F-22 -- 80%
• The DOD has emphasized the
need to make the systems/software
interface more seamless

• Some organizations see themselves as performing just one
discipline
– Software
– Systems
– Acquisition
• But…
– Software always must be part of some kind of system
– Systems that don’t have software are rare
– Acquisition can involve both
• Communication and cooperation with other disciplines,
even if they are external to our organization is vital

• Process area capability and organizational maturity
are similar concepts.
• The difference between them is that process area
capability deals with a set of processes relating to a
single process area or specific practice, while
organizational maturity pertains to a set of process
areas across an organization.

• Although the comparison of ratings and levels is an
advanced topic we don’t address in this tutorial, in
general terms, if a set of organizational processes
have been appraised at a particular maturity level,
the appraised processes may demonstrate a
comparable level of process area capability.

• A capability level is a well-defined
evolutionary plateau describing the
capability of a process area.
• There are six capability levels.
• Each level is a layer in the foundation
for continuous process improvement.
• Thus, capability levels are cumulative,
i.e., a higher capability level includes
