2 What is a CMM? Capability Maturity Model: A reference model of mature practices in a specified discipline, used to assess a groups capability to perform that discipline CMMs differ by –Discipline (software, systems, acquisition, etc.) –Structure (staged versus continuous) –How Maturity is Defined (process improvement path) –How Capability is Defined (institutionalization) Capability Maturity Model ® and CMM ® are used by the Software Engineering Institute (SEI) to denote a particular class of maturity models Capability Maturity Model®, CMM®, CMM Integration, and CMMI are service marks and registered trademarks of Carnegie Mellon University Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

6 CMMI to the Rescue! Integrates systems and software disciplines into one process improvement framework. Provides a framework for introducing new disciplines as needs arise. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

7 Bridging the Divide Systems engineering and software engineering processes are integrated. Integrates systems and software disciplines into one process improvement framework. Provides a framework for introducing new disciplines as needs arise. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

8 But We Dont Do That... Some organizations see themselves as performing just one discipline –Software –Systems –Acquisition But… –Software always must be part of some kind of system –Systems that dont have software are rare –Acquisition can involve both Communication and cooperation with other disciplines, even if they are external to our organization is vital Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

10 CMMI Models Source Models Capability Maturity Model for Software V2, draft C (SW-CMM V2C) EIA Interim Standard 731, System Engineering Capability Model (SECM) Integrated Product Development Capability Maturity Model, draft V0.98 (IPD-CMM) Combined System Engineering / Software Engineering model Can be applied to: –Just the software engineering projects in an organization –Just the system engineering projects in an organization –Both –IPPD can be used in either/both Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández CMMI-SE/SW Staged Representation CMMI-SE/SW Continuous Representation

11 Staged ML 1 ML2 ML3 ML4 ML5...for an established set of process areas across an organization Continuous...for a single process area or a set of process areas PA Process Area Capability PA Comparing Model Representations Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

12 Relating Process Area Capability and Organizational Maturity Process area capability and organizational maturity are similar concepts. The difference between them is that process area capability deals with a set of processes relating to a single process area or specific practice, while organizational maturity pertains to a set of process areas across an organization. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

13 Relating Process Area Capability and Organizational Maturity Although the comparison of ratings and levels is an advanced topic we dont address in this tutorial, in general terms, if a set of organizational processes have been appraised at a particular maturity level, the appraised processes may demonstrate a comparable level of process area capability. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

14 Why Do We Have Two Representations? Source Model Heritage –Software CMM--Staged –SECM--Continuous –IPD CMM--Hybrid Proponents for each type of representation were part of CMMI product development team. Selecting a single representation approach became too hard. A compromise was made to initially support two representations of the model with equivalent content. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

15 Advantages of the Staged Representation Provides a roadmap for implementing: –groups of process areas –sequencing of implementation Familiar structure for those transitioning from the SW- CMM Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

16 Advantages of the Continuous Representation Provides maximum flexibility for focusing on specific process areas according to business goals and objectives. Familiar structure for those transitioning from the systems engineering community. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

27 Process Area Capability Profile A process area capability profile may be represented by a set of points in two dimensions. –the process dimension What you do –the capability dimension How well you do it Capability (How well) Process Area (What you do) Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

28 The Process Dimension The values on this axis describe what processes (described within Process Areas) you perform. Process Area 1 Process Area n Process Area 2 Process Area 3 Capability Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

29 Process Areas Process Areas (PAs) are a cluster of related practices. They are the major building blocks in establishing process capability. Example PA: Requirements Management Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

Capability Process Area 1 Process Area n Process Area 2 Process Area 3 Process performed well and continuously improved Process not performed Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

34 Capability Levels A capability level is a well-defined evolutionary plateau describing the capability of a process area. There are six capability levels. Each level is a layer in the foundation for continuous process improvement. Thus, capability levels are cumulative, i.e., a higher capability level includes the attributes of the lower levels. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

35 The Capability Levels 5 Optimizing 4 Quantitatively Managed 3 Defined 2 Managed 1 Performed 0 Incomplete Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

36 Capability Levels are Cumulative Because capability levels build upon one another, there can be no gaps. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

37 Representing Process Capability The capability of a implemented process can be represented by a bar. Process Capability This point represents a higher level of capability than this point in a specific process area Process Area n Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

39 Realizing These Concepts in the CMMI Continuous Model Goals and Practices are the model elements used to realize the values on both the capability and process dimensions. –Goal A high level statement of the outcome to be achieved by effective implementation of a group of practices. –Practice A description of an action that is necessary to enact a key element of a process area. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

40 There Are Two Types of Goals and Practices Specific Goals and Specific Practices – realize the process dimension – therefore, they apply to a particular Process Area Generic Goals and Generic Practices – realize the capability dimension – therefore, they apply across all Process Areas Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

41 Example: Specific Goal and Specific Practice Specific Goal (from Requirements Management PA) –Requirements are managed and inconsistencies with project plans and work products are identified. Specific Practice (from Requirements Management PA) –Maintain bidirectional traceability among the requirements and the project plans and work products. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

42 Example: Generic Goal and Generic Practice Generic Goal (from Capability Level 1) – The process supports and enables achievement of the specific goals of the process area by transforming identifiable input work products to produce identifiable output work products. Generic Practice (from Capability Level 1) – Perform the basic activities of the process area to develop work products and provide services to achieve the specific goals of the process area. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

51 Maturity Levels A maturity level is a well-defined evolutionary plateau on the path to becoming a mature organization. There are five maturity levels. Each level is a layer in the foundation for continuous process improvement. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

52 The Maturity Levels Process unpredictable, poorly controlled and reactive Process characterized for projects and is often reactive Process characterized for the organization and is proactive Process measured and controlled Focus on process improvement Optimizing Quantitatively Managed Defined Performed Managed Optimizing Defined Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

53 Structure of the CMMI Staged Representation Maturity Level Process Area Generic GoalsSpecific Goals Commitment to Perform Ability to Perform Directing Implementation Verification Common Features Commitment to Perform: creates policies and secures sponsorship for process improvement efforts Ability to Perform: ensures that the project and/or organization has the resources it needs to pursue process improvement Directing Implementation: collects, measures, and analyzes data related to processes Verification: verifies that the projects and/or organizations activities conform to requirements, processes, and procedures Commitment to Perform: creates policies and secures sponsorship for process improvement efforts Ability to Perform: ensures that the project and/or organization has the resources it needs to pursue process improvement Directing Implementation: collects, measures, and analyzes data related to processes Verification: verifies that the projects and/or organizations activities conform to requirements, processes, and procedures Generic Practices Specific Practices Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

54 Maturity Levels Cannot Be Skipped A level provides a necessary foundation for effective implementation of processes at the next level. –Higher level processes are easily sacrificed without the discipline provided by lower levels. –The effect of innovation is obscured in a noisy process. Higher maturity level processes may be performed by organizations at lower maturity levels, with risk of not being consistently applied in a crisis. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

55 Process Areas Process Areas (PAs) are clusters of related practices performed collectively to achieve a set of goals. They are the major building blocks in establishing the process capability of an organization. Each process area has been defined to reside at a given maturity level. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

57 Example: Specific Goal and Specific Practice Specific Goal (from Requirements Management PA) –Requirements are managed and inconsistencies with project plans and work products are identified. Specific Practice (from Requirements Management PA) –Maintain bidirectional traceability among the requirements and the project plans and work products. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

58 Example: Generic Goal and Generic Practice Generic Goal (from Capability Level 1) – The process supports and enables achievement of the specific goals of the process area by transforming identifiable input work products to produce identifiable output work products. Generic Practice (from Capability Level 1) – Perform the basic activities of the process area to develop work products and provide services to achieve the specific goals of the process area. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

59 Common Features Common features are a means of categorizing Generic practices. – Commitment to perform: establishment of management policies – Ability to perform: establishment and maintenance of plans, resources, assigned responsibility and authority, and training – Directing implementation: measurement, control, and performance practices – Verification: ensure implementation and compliance Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

60 Another way to look at Common Features -1 Common feature categories are very similar across process areas. They are referred to as Institutionalization Common Features because they: – ensure the process areas are effective, repeatable and lasting – provide needed infrastructure support Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

61 Common Feature Examples -1 from Requirements Management Process Area Commitment to perform: –Establish and maintain an organizational policy for planning and performing the requirements management process. Ability to perform: –Train the people performing or supporting the requirements management process as needed. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

62 Common Feature Examples -2 from Requirements Management Process Area Directing implementation: –Place designated work products of the requirements management process under appropriate levels of configuration management. Verification: –Review the activities, status, and results of the requirements management process with higher level management and resolve issues. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

63 Summary -1 There is one CMMI Model with two representations, Staged and Continuous. The material in both representations is the same just organized differently. Each representation provides different ways of implementing processes The CMMI model should be applied using intelligence, common sense, and professional judgment. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández

64 Summary -2 Continuous –Flexible in its application so the organization can choose which areas to emphasize. –Provides equivalent staging to compare to staged representation. Staged –Structured for implementation based on proven grouping and ordering of processes. Técnicas de Calidad en el Software Derechos Reservados, Juan Antonio Vega Fernández
