- CMM describes about the software engineering alone where as CMM Integrated describes both software and system engineering. CMMI also incorporates the Integrated Procees and Product Development and the supplier sourcing.
CMM:
The first CMM (CMM v1.0) was developed for software and released in August 1990.Based on this success and the demand from other interests CMMs were developed for otherdisciplines and functions:a. Systems Engineeringb. Peoplec. Integrated Product Developmentd. Software Acquisitione. Software Quality Assurancef. Measurement.
CMMI:
The CMM Integration Project was formed to:
1. Establish a framework to integrate current and future models
2. Build an initial set of integrated models.
The source models that served as the basis for the CMMI include:
1. CMM for Software v2.0 Draft C
2. EIA ? 731 Systems Engineering
3. IPD CMM (IPD) v0.98a
Note - CMM = 'Capability Maturity Model', now called the CMMI ('Capability Maturity Model Integration'), developed by the SEI
