Quality Definition • Producer’s view of quality- Philip Crosby –Quality means conformance to requirements

• Customer’s view of quality – Joseph Juran –Quality is fitness for use

•

What is Process? Process - A set of activities, methods, practices and transformations that people use to develop and maintain software and associated products - A sequence of steps performed for a given purpose

Software Quality -Software product/service which meets the requirements documented in specifications -Software with less number of defects (Low Defect Density)

Capability Maturity Model Integration (CMMI) The Capability Maturity Model Integration for Software (CMMI) is a framework that describes the key elements of an effective software process. The CMMI describes an evolutionary improvement path from an ad hoc, immature process to a mature, disciplined process. KPA Each Key Process Area identifies a cluster of related activities that, when performed collectively, achieve a set of goals considered important for establishing process capability at that maturity level.

Understanding CMMI Representations • There are two types of representations in the CMMI models: ▫ staged ▫ continuous 

• A representation allows an organization to pursue different improvement objectives 

• The organization and presentation of the data are different in each representation. However, the content is the same. 

Staged Representation • Provides a proven sequence of improvements, each serving as a foundation for the next • Permits comparisons across and among organizations by the use of maturity levels • Provides an easy migration from the SW-CMM to CMMI • Provides a single rating that summarizes appraisal results and allows comparisons among

Quality Management System • A quality management system (QMS) is a policy, set of processes and procedures (Templates) required for planning and execution in the core business area of an organization

V.L.S. System QMS Structure

SEPG Activities • The SEPG must perform two main tasks: ▫ Establish and Maintain QMS ▫ Coordinating and sustaining process change and ▫ Monitoring Software Engineering activities • The SEPG should ensure that all changes to the process are documented and performed in a manner that will maintain consistency and CMMI compliance     
