An Introduction

Objective - Understand the difference between CMM & CMMI - Understand the Structure of CMMI.

Integration of Integrate Source Models –SW CMM v2.0c –EIA/IS 731 SECM –IPPD CMM draft v0.98 Consistent with ISO puneetd: EIA Interim Standard 731, system engineering capability model puneetd: EIA Interim Standard 731, system engineering capability model puneetd: Integrated Product & Process Development Capability Maturity Model puneetd: Integrated Product & Process Development Capability Maturity Model

Different Standards under CMMI Different body of Knowledge –Software (SW) –System Engineering (SE) –Integrated Product and Process Development (IPPD) –Supplier Sourcing (SS) Standards are combinations of different body of knowledge

Different Standards under CMMI –Software (SW) Covers the development of software systems. –System Engineering (SE) Development of total systems, which may or may not include software. Focus is on transforming customer needs, expectations and constraints into product solutions and support them. –Integrated Product and Process Development (IPPD) Contains – Process Management Project Management Support Engineering Processes –Supplier Sourcing (SS) – Use suppliers to perform functions or modifications to product.

Changes from SW CMM v1.1 Inclusion of Systems Engg. Two Representations New Process Areas (22/cmmi versus 18/cmm) New Generic Goals New Practices

Representation Staged –5 Maturity Levels –From SW CMM Continuous –6 Capability Levels –From EIA/IS 731 ISO 15504

Representation – Difference Staged Representation – We have the (Maturity Level)MLs as they are found in CMM. Process Areas are assigned to the UPPER fours of the five maturity levels (Managed, Defined, Quantitatively Managed, Optimizing) Provides a pre- defined roadmap for organizational improvement.

Representation – Difference Continuous Representation – Maturity Levels are replaced by Capability Levels (CL’s) as a measure assigned individually to each PA. Provides maximum flexibility for organizations to choose which processes to emphasize for improvement.

Process Area Process Area (PA) is a cluster of related practices. Practices are actions to be performed in order to achieve the goals of a process area. They are the major building blocks in establishing the process maturity of an organization. Each process area resides at a specific maturity level.

New Process Areas Level 2 (7 versus 6) –Measurement & Analysis Level 3 (11 versus 7) –Risk Management –Requirements Development –Technical Solution –Product Integration –Verification –Validation –Decision Analysis and Resolution –Organizational Environment for Integration

Process Area Comparison Level 2 SW CMM –Requirement Management –S/w Project Planning –S/w Project Tracking and Monitoring –S/w Subcontractor Management –S/w Quality Assurance –S/w Configuration Management CMM I –Requirements Management –Project Planning –Project Monitoring and Control –Supplier Agreement Management –Process and Product Quality Assurance –Configuration Management –Measurement and Analysis

Structure of CMMI Goal – A High level statement of the outcome to be achieved by effective implementation of group of practices. Specific Goals - 47 Generic Goals - 22 The concept of goals in CMMI is the same as in SW-CMM. All “Institutionalization related practices” satisfy “Generic Goals”.

Structure of CMMI Practices - A Description of expected actions to be performed in order to achieve the goals of a process areas. Specific Practices – These differ across process areas and equivalent to “Activities” in CMM. Generic Practices – These are common across all process areas and equivalent to “CO”, “AB”, VE” etc. General Practices support the Generic Goal of each PA.

Structure of CMMI Common Features – They are a means of categorizing generic practices. The categories are : Commitment to Perform – Creating management policies and securing sponsorship. Ability to Perform – Establishment and maintenance of plans, resources, assigning responsibility and authority and training. Directing Implementation – Measurement, Control and performance practices. Verifying Implementation – Ensure implementation and Compliance.
