Goals of CMMI
•
•
To improve software-development
processes
To evaluate capability of a software
company
Background
•
•
•
In early 1960's, many companies saw a
potential in software development and
started developing software without any
proper techniques or standards
This resulted in "Software Crisis" - US
military had several software projects
extended or canceled in 1980's .
US Air force then started a study to
understand and monitor the issue at the
Software Engineering Institute (SEI).
Software Engineering Institute (SEI)
•
•
•
A federally funded research and
development center operated by Carnegie
Mellon University
Mainly sponsored by the U.S. Department of
Defense, Office of the Secretary of Defense
(OSD) and the National Defense Industrial
Association
Developed CMMI with "a group of experts
from industry, government"1
Timeline of CMMI
•
•
•
CMMI is the successor of the capability
maturity model (CMM)
CMM was developed from 1987 until 1997
as a solution to avoid Software Crisis.
CMMI Version 1.1 was released in 2002.
CMMI Version 1.2 followed in August 2006,
and CMMI Version 1.3 in November 2010
Who can use CMMI to improve
quality?
•
•
“CMMI applies to teams, work groups,
projects, divisions, and entire organizations”2
CMMI is widely adopted in a variety of
industries, “including electronics, health
services, finance, insurance, and
transportation. User companies include
Boeing, General Motors, JP Morgan, Bosch,
and many others [...]”3

CMMI Features
•
•
CMMI Product Suite - a collection of all
model components, training material
components, and appraisal components.
organized in 3 main areas of interest called
constellations/models:
o
CMMI for Development (CMMI-DEV)
 Addresses the development of product and
service systems.
 Used by organizations in Defense, Healthcare,
Finance, Insurance, Telecommunications, and
other Industries.
CMMI Features (Cont.)
o CMMI for Acquisition ( CMMI-ACQ)
 Designed to aid organizations which are
acquiring products and services or outsourcing
the development of delivery of products and
services.
o CMMI for Services (CMMI-SVC)
 Purposed for organizations to get the same
results and benefits in their service deployment
efforts that they currently enjoy in their
development effort.
CMMI Features Constellations/Models
•
•
CMMI contains 22 process areas across the
3 constellations. 16 of them are considered
as core and found in all constellations
Each can be represented in one of two
ways: continuous or staged
o
Continuous
 Designed to allow user to focus on specific
processes that are considered important for the
organizations immediate business objectives.
 Measures an organization’s achievement with a
single process area of multiple selected
processes
CMMI Features Constellations/Models (Conti.)
o Staged
 Provides a sequence of improvements
 Measure the process improvement achievement
across multiple pre-planned process areas
CMMI Features - Appraisal Methods
•
Capability Levels (CL)
o adopted for appraising continuous representation
o totally 4 levels (0-Incomplete, 1-Performed, 2Managed and 3-Defined) 4
Maturity Levels (ML)
o adopted for appraising staged representation
o totally 5 levels, numbered 1 through 5
Standard CMMI Appraisal Method for Process
Improvement (SCAMPI)
o three classes of appraisals: A, B, C.
o A is the most rigorous and the only one that can
result in a level rating.

Relationships with Other
Approaches
•
“[...] is compatible with Agile, Scrum, ITIL,
Six Sigma, COBIT, ISO 9000, RUP, and
Lean. In fact, CMMI’s relationships with
these standards, methods, and technologies
goes beyond compatibility. They
complement each other [...]”5

Thoughts on CMMI
•
•
CMMI allows an organization to measure
how compliant its supplier and itself perform
in quality assurance process as a whole
based on the defined standard. This
definitely increases the confidence level of
the customers in the final product.
An organization can achieve bigger
improvements without introducing a lot of
additional cost, as CMMI is compatible with
other approaches in terms of process areas,
e.g. Agile.
