Before Proceeding further, we need to understand CMMi terminology first please have a glance at the following table –
Concept | Definition |
AMPLIFICATION | Amplifications are informative model components that contain information relevant to a particular discipline. For example, to find amplification for software engineering, one would look in the model for items labeled “For Software Engineering.” The same is true for other disciplines. |
CAPABILITY LEVEL | Achievement of process improvement within an individual process area. A capability level is defined by the appropriate specific and generic practices for a process area. |
CMMI MODEL | A model generated from the CMMI Framework. |
CONTINUOUS REPRESENTATION | A capability maturity model structure wherein capability levels provide a recommended order for approaching process improvement within each specified process area. |
GENERIC GOAL | A required model component that describes characteristics that must be present to institutionalize processes that implement a process area. |
GENERIC PRACTICE | An expected model component that is considered important in achieving the associated generic goal. The generic practices associated with a generic goal describe the activities that are expected to result in achievement of the generic goal and contribute to the institutionalization of the processes associated with a process area. |
GENERIC PRACTICE ELABORATIONS | An informative model component that appears after a generic practice to provide guidance on how the generic practice should be applied to the process area. |
GOAL | A required CMMI component that can be either a generic goal or a specific goal. The word goal in a CMMI model always refers to a model component (e.g., generic goal and specific goal). |
MATURITY LEVEL | Degree of process improvement across a predefined set of process areas in which all goals in the set are attained. |
PROCESS AREA | A cluster of related practices in an area that, when implemented collectively, satisfies a set of goals considered important for making improvement in that area. All CMMI process areas are common to both continuous and staged representations. |
REFERENCE | An informative model component that points to additional or more detailed information in related process areas. |
SPECIFIC GOAL | A required model component that describes the unique characteristics that must be present to satisfy the process area. |
SPECIFIC PRACTICE | An expected model component that is considered important in achieving the associated specific goal. The specific practices describe the activities expected to result in achievement of the specific goals of a process area. |
STAGED REPRESENTATION | A model structure wherein attaining the goals of a set of process areas establishes a maturity level; each level builds a foundation for subsequent levels. |
SUBPRACTICE | An informative model component that provides guidance for interpreting and implementing specific or generic practices. Subpractices may be worded as if prescriptive, but they are actually meant only to provide ideas that may be useful for process improvement. |
WORK PRODUCT | In the CMMI Product Suite, a useful result of a process. This can include files, documents, products, parts of a product, services, process descriptions, specifications, and invoices. A key distinction between a work product and a product component is that a work product is not necessarily part of the end product. |
All CMMI models contain multiple process areas (PAs). A PA has 1 to 4 goals, and each goal is comprised of practices. These goals and practices are called specific goals and practices, as they describe activities that are specific to a single process area. An additional set of goals and practices applies across all of the process areas; this set is called generic goals and practices.
The latest version of Capability Maturity Model Integration (CMMi) is Version 1.2 which contains 22 process areas(as Listed Below) that describe the aspects of product development that are to be covered by organizational processes.

Maturity Levels
There are five maturity levels. However, maturity level ratings are awarded for levels 2 through 5.
Maturity Level 1 - Ad hoc (Chaotic)
It is characteristic of processes at this level that they are (typically) undocumented and in a state of dynamic change, tending to be driven in an ad hoc, uncontrolled and reactive manner by users or events. This provides a chaotic or unstable environment for the processes.
This Level does not have any KPA linked with it.
Maturity Level 2 – Repeatable
It is characteristic of processes at this level that some processes are repeatable, possibly with consistent results. The processes may not repeat for all the projects in the organization. The organization may use some basic project management to track cost and schedule.
Process discipline is unlikely to be rigorous, but where it exists it may help to ensure that existing practices are retained during times of stress. When these practices are in place, projects are performed and managed according to their documented plans.
Following are the KPA’s linked to this level
- CM - Configuration Management
- MA - Measurement and Analysis
- PMC - Project Monitoring and Control
- PP - Project Planning
- PPQA - Process and Product Quality Assurance
- REQM - Requirements Management
- SAM - Supplier Agreement Management
Maturity Level 3 – Defined
It is characteristic of processes at this level that there are sets of defined and documented standard processes established and subject to some degree of improvement over time. These standard processes are in place (i.e., they are the AS-IS processes) and used to establish consistency of process performance across the organization. Projects establish their defined processes by applying the organization’s set of standard processes, tailored, if necessary, within similarly standardized guidelines.
Following are the KPA’s linked to this level
- DAR - Decision Analysis and Resolution
- IPM - Integrated Project Management +IPPD
- OPD - Organizational Process Definition +IPPD
- OPF - Organizational Process Focus
- OT - Organizational Training
- PI - Product Integration
- RD - Requirements Development
- RSKM - Risk Management
- TS - Technical Solution
- VAL - Validation
- VER – Verification
Maturity Level 4 – Managed
It is characteristic of processes at this level that, using process metrics, management can effectively control the AS-IS process (e.g., for software development ). In particular, management can identify ways to adjust and adapt the process to particular projects without measurable losses of quality or deviations from specifications. Process Capability is established from this level.
Following are the KPA’s linked to this level
- QPM - Quantitative Project Management
- OPP - Organizational Process Performance
Maturity Level 5 – Optimized
It is characteristic of processes at this level that the focus is on continually improving process performance through both incremental and innovative technological changes/improvements.
Following are the KPA’s linked to this level
- CAR - Causal Analysis and Resolution
- OID - Organizational Innovation and Deployment
Goals and Practices
There are two categories of goals and practices: generic and specific. Specific goals and practices are specific to a process area. Generic goals and practices are a part of every process area. A process area is satisfied when organizational processes cover all of the generic and specific goals and practices for that process area.
Each process area is defined by a set of goals and practices. These goals and practices appear only in that process area.
Generic goals and practices are a part of every process area.
