Capability Maturity Model Integration (CMMI) COMP 587 - Group Assignment #1 Ario Nejad, Davit Stepanyan, Ian Jackman, Sebastian Henneberg, Wan Chi Chio
Goals of CMMI • To improve software-development processes • To evaluate capability of a software company
Background • In early 1960's, many companies saw a potential in software development and started developing software without any proper techniques or standards • This resulted in "Software Crisis" - US military had several software projects extended or canceled in 1980's . • US Air force then started a study to understand and monitor the issue at the Software Engineering Institute (SEI).
Software Engineering Institute (SEI) • A federally funded research and development center operated by Carnegie Mellon University • Mainly sponsored by the U.S. Department of Defense, Office of the Secretary of Defense (OSD) and the National Defense Industrial Association • Developed CMMI with "a group of experts from industry, government"1 1. http://en.wikipedia.org/wiki/Capability_Maturity_Model_Integration
Timeline of CMMI • CMMI is the successor of the capability maturity model (CMM) • CMM was developed from 1987 until 1997 as a solution to avoid Software Crisis. • CMMI Version 1.1 was released in 2002. CMMI Version 1.2 followed in August 2006, and CMMI Version 1.3 in November 2010
Who can use CMMI to improve quality? • “CMMI applies to teams, work groups, projects, divisions, and entire organizations”2 • CMMI is widely adopted in a variety of industries, “including electronics, health services, finance, insurance, and transportation. User companies include Boeing, General Motors, JP Morgan, Bosch, and many others [...]”3 2. http://www.sei.cmu.edu/cmmi/ 3. http://www.sei.cmu.edu/cmmi/why/index.cfm
CMMI Features • CMMI Product Suite - a collection of all model components, training material components, and appraisal components. • organized in 3 main areas of interest called constellations/models: • CMMI for Development (CMMI-DEV) • Addresses the development of product and service systems. • Used by organizations in Defense, Healthcare, Finance, Insurance, Telecommunications, and other Industries.
CMMI Features (Cont.) • CMMI for Acquisition ( CMMI-ACQ) • Designed to aid organizations which are acquiring products and services or outsourcing the development of delivery of products and services. • CMMI for Services (CMMI-SVC) • Purposed for organizations to get the same results and benefits in their service deployment efforts that they currently enjoy in their development effort.
CMMI Features - Constellations/Models • CMMI contains 22 process areas across the 3 constellations. 16 of them are considered as core and found in all constellations • Each can be represented in one of two ways: continuous or staged • Continuous • Designed to allow user to focus on specific processes that are considered important for the organizations immediate business objectives. • Measures an organization’s achievement with a single process area of multiple selected processes
CMMI Features - Constellations/Models (Conti.) • Staged • Provides a sequence of improvements • Measure the process improvement achievement across multiple pre-planned process areas
CMMI Features - Appraisal Methods • Capability Levels (CL) • adopted for appraising continuous representation • totally 4 levels (0-Incomplete, 1-Performed, 2-Managed and 3-Defined) 4 • Maturity Levels (ML) • adopted for appraising staged representation • totally 5 levels, numbered 1 through 5 • Standard CMMI Appraisal Method for Process Improvement (SCAMPI) • three classes of appraisals: A, B, C. • A is the most rigorous and the only one that can result in a level rating. 4. www.sei.cmu.edu/reports/10tr032.pdf
Relationships with Other Approaches • “[...] is compatible with Agile, Scrum, ITIL, Six Sigma, COBIT, ISO 9000, RUP, and Lean. In fact, CMMI’s relationships with these standards, methods, and technologies goes beyond compatibility. They complement each other [...]”5 5.http://www.sei.cmu.edu/cmmi/compatibility/index.cfm
Thoughts on CMMI • CMMI allows an organization to measure how compliant its supplier and itself perform in quality assurance process as a whole based on the defined standard. This definitely increases the confidence level of the customers in the final product. • An organization can achieve bigger improvements without introducing a lot of additional cost, as CMMI is compatible with other approaches in terms of process areas, e.g. Agile.
