An Introduction

1. An Introduction

2. Objective • Understand the difference between CMM & CMMI • Understand the Structure of CMMI.

3. Integration of • Integrate Source Models • SW CMM v2.0c • EIA/IS 731 SECM • IPPD CMM draft v0.98 • Consistent with ISO 15504 puneetd: EIA Interim Standard 731, system engineering capability model puneetd: Integrated Product & Process Development Capability Maturity Model

4. 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

5. 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.

6. 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

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

8. 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.

9. 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.

12. Comparison • Continuous Staged • Representation Representation • Level Capability Levels Maturity Levels • 0 Incomplete N/A • 1 Performed Initial • Managed Managed • Defined Defined • 4 Quantitatively Quantitatively • Managed Managed • 5 Optimizing Optimizing

13. 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.

19. 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”.

20. 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.

21. 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.

22. Summary • Different Standards under CMMI • Changes from CMM to CMMI • 2 Representations • Comparison between Representations • Process Areas • Structure
