Introduction To CMMI

Today we will discuss about Improvements from Adopting Software CMM, Benefits of Continuing Process Improvement, CMM"I" - Improvement, CMM"I" - Integration, Improving on The Software CMM, How CMMI can benefit you and other necessary topics.

Improvements from Adopting Software CMM

Benefits of Continuing Process Improvement

SEI Software CMM Level 5: For the Right Reasons

Defects are now nearly all found and fixed beforetesting begins.

Defects escaping into the field have been reduced from 11% to practically 0%.

Programs consistently reach customer satisfaction and performance targets.

Peer reviews increase total project costs by 4%, but reduced rework during testing by 31%. R.O.I. is 7.75:1.

CMMI Improvement

The CMMI Product Suite provides a foundation for enterprise-wide improvement and adds

            --new emphasis on products and services as well as process
            --emphasis on both process capability and organizational maturity
            --early emphasis on measurement and analysis

The CMMI model improves upon Software CMM V1.1 and Software CMM V2.0 Draft C.

CMMI Integration

Provides expanded model scope for integration

            --Integrated Product Management
            --Integrated Supplier Management
            --Decision Analysis and Resolution
            --Relevant Stakeholder planning and execution
            --Inclusion of the Integrated Product and Process Development                    body of knowledge

Improving on the Software CMM

CMMI Models improve on the best practices in Software CMM Version 2.0 Draft C:

            --Incorporates 4+ additional years of learning
            --More explicitly links management and engineering activities to                    business objectives
            --Expands the scope of and visibility into the product life cycle and             engineering activities to ensure the product or service meets                 customer expectations
            --Incorporates additional areas of best practice (e.g.,                                   measurement, risk management, bi-directional traceability in                    requirements management, decision analysis and resolution,                    and supplier management)
            --Captures more robust high-maturity practices
            --Addresses additional generic practices needed for                                institutionalization
            --More fully complies with relevant ISO standards

CMMI Can Benefit You

CMMI provides

         --Efficient, effective assessment and improvement across multiple                 process disciplines in an organization
         --Improvements to best practices incorporated from the Software                 CMM
         --A common, integrated vision of improvement for all elements of                 an organization
         --A means of representing new discipline-specific information in a                 standard, proven process-improvement context
