What is CMMI? The Capability Maturity Model Integration (CMMI) is a capability maturity model developed by the Software Engineering Institute, part of Carnegie Mellon University in Pittsburgh, USA. The CMMI principal is that “the quality of a system or product is highly influenced by the process used to develop and maintain it”. CMMI can be used to guide process improvement across a project, a division, or an entire organization. CMMI provides: Guidelines for processes improvement An integrated approach to process improvement Embedding process improvements into a state of business as usual A phased approach to introducing improvements CMMI Models CMMI consists of three overlapping disciplines (constellations) providing specific focus into the Development, Acquisition and Service Management domains respectively: CMMI for Development (CMMI-DEV) – Product and service development CMMI for Services (CMMI-SVC) – Service establishment, management, and delivery CMMI for Acquisition (CMMI-ACQ) – Product and service acquisition Originating in software engineering, CMMI has been highly generalised over the years to embrace other business processes such as the development of hardware products, service delivery and purchasing which has had the effect of abstracting CMMI. CMMI Model Framework Depending on the CMMI constellation (CMMI-DEV, CMMI-SVC & CMMI ACQ) used, the process areas it contains will vary. The table below lists the process areas that are present in all CMMI constellations. This collection of eight process areas is called the CMMI Model Framework, or CMF. Capability Maturity Model Integration (CMMI) Framework CMMI Maturity Levels There are five CMMI maturity levels. However, maturity level ratings are only awarded for levels 2 through 5. CMMI Maturity Level 2 – Managed CM – Configuration Management MA – Measurement and Analysis PMC – Project Monitoring and Control PP – Project Planning PPQA – Process and Product Quality Assurance REQM – Requirements Management SAM – Supplier Agreement Management CMMI Maturity Level 3 – Defined DAR – Decision Analysis and Resolution IPM – Integrated Project Management +IPPD OPD – Organizational Process Definition +IPPD OPF – Organizational Process Focus OT – Organizational Training PI – Product Integration RD – Requirements Development RSKM – Risk Management TS – Technical Solution VAL – Validation VER – Verification CMMI Maturity Level 4 – Quantitatively Managed QPM – Quantitative Project Management OPP – Organizational Process Performance CMMI Maturity Level 5 – Optimizing CAR – Causal Analysis and Resolution OID – Organizational Innovation and Deployment CMMI Appraisals Certification does not exist as a concept in CMMI, rather an organisation is appraised. and can be awarded a maturity level rating (1-5) or a capability level achievement profile. Many organizations find value in measuring their progress by conducting an appraisal in order to: Determine how well the organization’s processes compare to CMMI best practices, and to identify areas where improvement can be made Inform external customers and suppliers of how well the organization’s processes compare to CMMI best practices Meet the contractual requirements of one or more customers Appraisals must conform to the requirements defined in the Appraisal Requirements for CMMI (ARC) document. There are three classes of appraisals, A, B and C, focusing on identifying improvement opportunities and comparing processes to CMMI best practices. Appraisal teams use a CMMI model and ARC-conformant appraisal method to guide their evaluation of the organization and their reporting of conclusions. The Standard CMMI Appraisal Method for Process Improvement (SCAMPI) is an appraisal method that meets all of the ARC requirements. A class A appraisal is the only one that can result in a level rating. To Achieve CMMI follow the link below, http://www.softwaretestinghelp.com/achieve-level-5-maturity-for-qa-testing-process/
