CMMI - Glossary
Ability to perform − A common feature of CMMI model process areas with a staged representation that groups the generic practices related to ensuring that the project and/or organization has the resources it needs.
Acceptance criteria − The criteria that a product or product component must satisfy to be accepted by a user, customer, or other authorized entity.
Acceptance testing − Formal testing conducted to enable a user, customer, or other authorized entity to determine whether to accept a product or product component.
Achievement profile − In the continuous representation, a list of process areas and their corresponding capability levels that represent the organization's progress for each process area while advancing through the capability levels.
Acquisition − The process of obtaining, through contract, any discrete action or proposed action by the acquisition entity that would commit to invest for obtaining products and services.
Acquisition strategy − The specific approach to acquiring products and services that is based on considerations of supply sources, acquisition methods, requirements specification types, contract or agreement types, and the related acquisition risk.
Adequate − Adequate, appropriate, and as needed appear in CMMI to allow managers at all levels and practitioners to interpret the specific and generic goals and practices in light of the organization's business objectives. For example, a Generic Practice for the process area of Risk Management states− "Provide adequate resources for performing the risk management process, developing the work products, and providing the services of the process." Adequate could be satisfied by Numbers of people, People who must monitor the risks etc.
Advanced practices − In the continuous representation, all the specific practices with a capability level of two or higher.
Agreement/contract requirements − All technical and non-technical requirements related to an acquisition.
Allocated requirement − Requirement that levies all or part of the performance and functionality of a higher level requirement on a lower level architectural element or design component.
Alternative practice − A practice that is a substitute for one or more generic or specific practices contained in CMMI models that achieves an equivalent effect toward satisfying the generic or specific goal associated with model practices. Alternative practices are not necessarily one-for-one replacements for the generic or specific practices.
Appraisal − An appraisal is an examination of one or more processes by a trained team of professionals using an appraisal reference model as the basis for determining strengths and weaknesses.
Appraisal findings − The conclusions of an appraisal that identify the most important issues, problems, or opportunities within the appraisal scope. It includes, at a minimum, strengths and weaknesses based on valid observations.
Appraisal participants − Members of the organizational unit who participate in providing information during the appraisal.
Appraisal rating − As used in CMMI appraisal materials, the value assigned by an appraisal team to either (1) a CMMI goal or process area, (2) the capability level of a process area, or (3) the maturity level of an organizational unit. The rating is determined by enacting the defined rating process for the appraisal method being employed.
Appraisal reference model − As used in CMMI appraisal materials, the CMMI model to which an appraisal team correlates implemented process activities.
Appraisal scope − The definition of the boundaries of the appraisal encompassing the organizational limits and the CMMI model limits.
Appraisal team leader − A person who leads the activities of an appraisal and has satisfied the qualification criteria for experience, knowledge, and skills defined by the appraisal method.

Audit − An independent examination of a work product or set of work products to determine whether requirements are being met.
Base measure − A distinct property or characteristic of an entity and the method for quantifying it.
Base practices − In the continuous representation, all the specific practices with a capability level of 1.
Baseline − The term baseline is normally used to denote such a reference point. A baseline is an approved snapshot of the system at appropriate points in the development life cycle. A baseline establishes a formal base for defining subsequent change. Without this line or reference point, the notion of change is meaningless.
Business objectives − Senior-management-developed strategies designed to ensure an organization's continued existence and enhance its profitability, market share, and other factors influencing the organization's success.
Capability evaluation − An appraisal by a trained team of professionals used as a discriminator to select suppliers, for contract monitoring, or for incentives. Evaluations are used to help decision makers make better acquisition decisions, improve subcontractor performance, and provide insight to a purchasing organization.
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.
Capability level profile − In the continuous representation, a list of process areas and their corresponding capability levels. The profile may be an achievement profile when it represents the organization's progress for each process area while advancing through the capability levels. Or, the profile may be a target profile when it represents an objective for process improvement.
Capability maturity model − A capability maturity model (CMM) contains the essential elements of effective processes for one or more disciplines. It also describes an evolutionary improvement path from ad hoc, immature processes to disciplined, mature processes with improved quality and effectiveness.
Capable process − A process that can satisfy its specified product quality, service quality, and process performance objectives.
Causal analysis − The analysis of defects to determine their cause.
Change management − Judicious use of means to effect a change, or proposed change, on a product or service.

[IEEE Std 610.1990]
CMMI Model − Since the CMMI Framework can generate different models based on the needs of the organization using it, there are multiple CMMI models. Consequently, the phrase "CMMI MODEL" could be any one of many collections of information. The phrase "CMMI models" refers to one, some, or the entire collection of possible models that can be generated from the CMMI Framework.
Configuration status accounting − An element of configuration management consisting of the recording and reporting of information needed to manage a configuration effectively. This information includes a listing of the approved configuration identification, the status of proposed changes to the configuration, and the implementation status of approved changes.

Corrective action − Acts or deeds used to remedy a situation, remove an error, or adjust a condition.
COTS − Items that can be purchased from a commercial vendor.
Customer − A customer is the individual, project, organization, group, and so forth that is responsible for accepting the product or for authorizing payment. The customer is external to the project but not necessarily external to the organization. The term customer also serves as a variable when we discuss requirements gathering or elicitation.
Data management − Principles, processes, and systems for the sharing and management of data.

Derived requirements − Requirements that are not explicitly stated in the customer requirements, but are inferred (1) from contextual requirements (e.g., applicable standards, laws, policies, common practices, and management decisions), or (2) from requirements needed to specify a product component. Derived requirements can also arise during analysis and design of components of the product or system.
Design review − A formal, documented, comprehensive, and systematic examination of a design to evaluate the design requirements and the capability of the design to meet these requirements, and to identify problems and propose solutions.
Development − Development, as it is used throughout CMMI, implies maintenance activities as well as development activities. Experience has shown that best practices should be applied to both development and maintenance projects if an organization is in pursuit of engineering excellence.
Developmental plan − A plan for guiding, implementing, and controlling the design and development of one or more products.
Directing implementation − A common feature of CMMI model process areas with a staged representation that groups the generic practices related to managing the performance of the process, managing the integrity of its work products, and involving relevant stakeholders.
Discipline amplification − Model components that provide guidance for interpreting model information for specific disciplines (e.g., systems engineering, or software engineering) are called "DISCIPLINE AMPLIFICATIONS." Discipline amplifications are added to other model components where necessary. These are easy to locate because they appear on the right side of the page and have a title indicating the discipline that they address (for example, "For Software Engineering").

Functional architecture − The hierarchical arrangement of functions, their internal and external (external to the aggregation itself) functional interfaces and external physical interfaces, their respective functional and performance requirements, and their design constraints.
Generic goal − GENERIC GOALS are called "generic" because the same goal statement appears in multiple process areas. In the staged representation, each process area has only one generic goal. Achievement of a generic goal in a process area signifies improved control in planning and implementing the processes associated with that process area, thus indicating whether these processes are likely to be effective, repeatable, and lasting. Generic goals are required model components and are used in appraisals to determine whether a process area is satisfied.
Generic practice − GENERIC PRACTICES provide institutionalization to ensure that the processes associated with the process area will be effective, repeatable, and lasting. Generic practices are categorized by generic goals and common features and are expected components in CMMI models. (Only the generic practice title, statement, and elaborations appear in the process areas.)
Generic practice elaboration − After the specific practices, the generic practice titles and statements appear that apply to the process area. After each generic practice statement, an elaboration may appear in plain text with the heading "Elaboration". The GENERIC PRACTICE ELABORATION provides information about how the generic practice should be interpreted for the process area. If there is no elaboration present, the application of the generic practice is obvious without an elaboration.
Goal − A "GOAL" is a required CMMI component that can be either a generic goal or a specific goal. When you see the word "goal" in a CMMI model, it always refers to model components (for example, generic goal, specific goal).
Incomplete process − A process that is not performed or is only performed partially (also known as capability level 0). One or more of the specific goals of the process area are not satisfied.
Independent group − In the Process and Product Quality Assurance process area, see the discussion of a "group that is independent" in the introductory notes.
Informative CMMI components − CMMI components that help model users understand the required and expected components of a model. These components may contain examples, detailed explanations, or other helpful information. Sub-practices, notes, references, goal titles, practice titles, sources, typical work products, discipline amplifications, and generic practice elaborations are informative model components.

Training − In the Organizational Training process area, see the definition of .training. in the introductory notes.
Unit testing − Testing of individual hardware or software units or groups of related units.
Validation − Validation demonstrates that the product, as provided, (or as it will be provided) will fulfill its intended use in the operational environment. Validation assures that "You built the right thing."
Verification − Verification includes verification of the product and intermediate work products against all selected requirements, including customer, product, and product component requirements. Verification is inherently an incremental process. It begins with the verification of the requirements, progresses through the verification of the evolving work products, and culminates in the verification of the completed product. Verification addresses whether the work product properly reflects the specified requirements. Verification assures "You built it right."
Verifying implementation − A common feature of CMMI model process areas with a staged representation that groups the generic practices related to review by higher level management, and objective evaluation of conformance to process descriptions, procedures, and standards.
Version control − The establishment and maintenance of baselines and the identification of changes to baselines that make it possible to return to the previous baseline.
Weakness − As used in CMMI appraisal materials, the ineffective, or lack of, implementation of one or more CMMI model practices.
Work breakdown structure − An arrangement of work elements and their relationship to each other and to the end product.
Work product − The term WORK PRODUCT is used throughout the CMMI Product Suite to mean any artifact produced by a process. These artifacts can include files, documents, parts of the product, services, processes, specifications, and invoices. Examples of processes to be considered as work products include a manufacturing process, a training process, and a disposal process for the product. A key distinction between a WORK PRODUCT and a product component is that a work product need not be engineered or part of the end product.
Work product and task attributes − Characteristics of products, services, and project tasks used to help in estimating project work. These characteristics include items such as size, complexity, weight, form, fit, or function. They are typically used as one input to deriving other project and resource estimates (e.g., effort, cost, schedule)
