What is CMMI leavels?..

Answer / guest

Hai

CMM = 'Capability Maturity Model', now called the CMMI
('Capability Maturity Model Integration'), developed by the
SEI. It's a model of 5 levels of process 'maturity' that
determine effectiveness in delivering quality software. It
is geared to large organizations such as large U.S. Defense
Department contractors. However, many of the QA processes
involved are appropriate to any organization, and if
reasonably applied can be helpful. Organizations can
receive CMMI ratings by undergoing assessments by qualified
auditors.
Level 1 - characterized by chaos, periodic panics,
and heroic efforts required by individuals to successfully
complete projects. Few if any processes in place;
successes may not be repeatable.

Level 2 - software project tracking, requirements
management,realistic planning, and configuration management
processes are in place; successful practices can be
repeated.

Level 3 - standard software development and
maintenance processes are integrated throughout an
organization; a Software Engineering Process Group is is in
place to oversee software processes, and training programs
are used to ensure understanding and compliance.

Level 4 - metrics are used to track productivity,
processes,and products. Project performance is predictable,
and quality is consistently high.

Level 5 - the focus is on continouous process
improvement. The impact of new processes and technologies
can be predicted and effectively implemented when required.
