INTRODUCTION
What is the CMMI? Capability Maturity Model Integration, currently version 2.0 A process improvement framework that provides organizationswith the essential elements of effective processes (bestpractices) that ultimately lead to performance improvement A maturity model & de facto standard for process improvement,that defines a set of best practices that help organizations in thedevelopment, acquisition & operation of sw/hw products &services Created by the Software Engineering Institute (SEI) of CarnegieMellon University (CMU), currently maintained by the CMMIInstitute & ISACA The most internationally recognized referential for softwareprocess improvement (SPI), implementend in almost alldeveloped countries

MODEL VIEWS
CMMI ViewsPredefined views of the CMMI V2.0 Product Suite: Development (CMMI-DEV) - Use processes to developquality products and services to meet the needs ofcustomers and end users. Services (CMMI-SVC) - Use processes to deliver, manage,and improve services to meet customer needs. Supplier Management (CMMI-SPM) - Use processes toidentify, select, and manage suppliers and theiragreements.Each view is a subset of the CMMI model, i.e., a selection ofmodel components (usually, practice areas).
Example: CMMI DEV V2.0 Practice areas(optional)
CAPABILITY LEVELS & MATURITYLEVELS
Evolutionary (capability) levelsEach CMMI practice is classified at an evolutionary level 1 to 5
Maturitylevels Maturity Level 0: theintent of all predefinedPAs is not achieved Maturity Level N (1 to5): the intent of allpredefined PAs up toand including Level Npractices is achieved atPractice Group N Ratings are given onlyfor ML2 to ML53/15/2021

Summary The CMMI process maturity model is an integrated processimprovement model that supports both staged andcontinuous process improvement. Process improvement in the CMMI model is based onreaching a set of goals related to good softwareengineering practice and describing, standardizing andcontrolling the practices used to achieve these goals. The CMMI model includes recommended practices thatmay be used, but these are not obligatory.
Review Questions and Exercises What is the CMMI? How are the practices in the model grouped? What are the maturity levels? Give examples of model views. Build a conceptual model (metamodel) of the CMMI V2.0Model using a UML class diagram

CMMI-DEV and CMMI-SVC Could we leverage the overlap between CMMI-DEV and CMMI-SVC? CMMI-DEV v1.3 Has a total of 18 Process Areas (PAs) From which 17 PA directly apply to Pasadena Operations The Supplier Agreements Management (SAM) PA is not implemented For Maturity Level 3 12 out of the 18 PA are the same for CMMIDEV and CMMI- -SVCFile Size: 236KB
CMMI-DEV process assets can be reused in adopting CMMI-SVC Substantial overlap between CMMI-SVC process areas and ISO/IEC 20000 processes CMMI-SCV will be supported by SEI Partners (SEI 2007) 226 Partners offer Introduction to CMMI 248 Partners offer SCAMPI appraisal services 54,460 Introduction to CMMI courses since 2000
