Main Goals of CMM
• Provide an organization with the framework for
improving its processes and its ability to manage
the development, acquisition, and maintenance
of products or services.
o
This is provided through appraisals and assessments of the
organization's processes, based on CMM criteria.
• Provide “clients” with a maturity scale rating for
potential vendors
o
The more mature an organization (Higher CMM Rating), the
more likely its processes and development are to succeed
RDJ
First Appearance of CMM
• The process maturity model CMM is based on
was first described by Watts Humphrey in the
book Managing the Software Process
• CMM was first published in a Technical Report in
1993 and as a book in 1995

o
“Capability Maturity Model for Software”

What motivated CMM/CMMI?
• In the 1980's military projects ran over budget.
o
United States Air Force funded SEI study
• The model CMM was being used for software
development, but problems were found when
multiple instances of CMM were being used
o
o
CMMI was created to address this issue
CMMI is Capability Maturity Model Integrated

CMM vs. Six Sigma
CMM - Designed with Software in mind
•
•
•
•
Design gols - These do not focus on the customer
Organization Improvement - Improve methods and processes
Key Process Areas: Initial, Repeatable, Defined, Managed, Optimizing
Planning and Management oriented
Six Sigma
•
•
•
•
•
Design goals - customer demands & enterprise strategy
Quality Characteristics - Reduce number of errors to n-LOC.
Design alternatives - High level design
Plan for verification
Pilot runs
CMM & Six Sigma
These work together well at the higher CMM levels.
• CMM Level 5
o Mostly in line together although CMM is an organizational
change model
• CMM Level 1-4
o Although Six Sigma can be used at these levels its goals
are competing with CMM.
CMM vs. ISO
• CMM
o
o
o
o
Continuous process improvement
Scope – Software.
Customer Satisfaction is not part of CMM
Concept - Best practices derived from industry leaders, and a rating system
• ISO
o
o
o
o
Acceptable quality system
Scope – Hardware, software, processed materials and services.
Customer satisfaction is important in ISO requirements.
Concept - Certification tool
BK
CMM & ISO
They both can be used together
•
Overlap (not 100%, but significant enough)
o If you are at level 3 CMM it is usually easy to get ISO 9001 certified (level 2 can
also, without too much grief.)
o Both are for improvement of software
o ISO is to conform to ISO standards, CMM is to follow industry standards. You can
use a industry standard that conforms to ISO.
Uses of this Approach
• Regulations and mandates:
• Based on it history, most of government contractors use it
to demonstrated they are capable of handling the
projects.
• It is also a way for some companies to distinguish
themselves from others.
Example: Motorola in Bangalore
RS
Uses of this Approach
• To deal with Performance problems
• Software companies with motivation to improve
quality and delivery of their product.
• When a problem is seen with current product,
and when an organization wants to avoid
repeating the same problem.
RS
Opinion
• This approach has years solid research, and
good amount of practical usage to say that
it is a vital methodology to improve
process.
• It is well structured and constantly updated
to address new issues.
RS
Opinion
• Complex process for everyone in organization to
understand and implement.
• It takes time and patience to climb up the
phases.
• For it to work well for todays technology
companies, it needs to have good integration with
agile methodologies as that's the de-fecto
standard most companies are implementing.
RS
Organization Behind CMM
• Development of the model by the US
Department of Defense Software Engineering
Institute (SEI) began in 1986.
• Carnegia Mellon University in Pittsburgh.
• United State Air Force.
• Board of visitors of the SEI.
KA
Main Features
• The organization's activities are explicitly linked to the
business objectives.
• The visibility into the organization's activities is
increased to help you ensure that your product or service
meets the customer's expectations.
• Learn from new areas of best practice.
• Maturity model.
• Structure
- Maturity Levels.
- Key Process Areas.
- Goals.
- Common Features
KA
Main Features
• Levels
- Initial.
- Managed.
- Defined.
-Quantitatively managed.
- Optimizing.
