• Quality Definition• What is Process?• SDLC processes• What is CMMi?• Five maturity levels of CMMi• What is QMS• VLS QMS Structure • SEPG Activities• What is OSSP?
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?
- 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
Process
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 froman ad hoc, immature process to a mature, disciplined process.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
Refer Process Improvement process andSEPG plan
OSSP (Organisation Standard Software Process)
A set of Organization wide Process Description, Guidelines, Templates, Standards, Tailoring Guidelines, Analysis Reports, Metrics form the OSSP
Defined and Approved by SEPG (Software Engineering Process Gr.)
Monitored by SQAG (Software Quality Assurance Gr.)
