A change request is declarative, i.e. it states what needs to be accomplished, but leaves out how the change should be carried out. Important elements of a change request are an ID, the customer (ID), the deadline (if applicable), an indication whether the change is required or optional, the change type (often chosen from a domain-specific ontology) and a change abstract, which is a piece of ...
The customer is the role that requests a change due to problems encountered or new functionality requirements; this can be a person or an organizational entity and can be in- or external to the company that is asked to implement the change. Project manager: The project manager is the owner of the project that the CHANGE REQUEST concerns. In ...
Software development effort estimation is a difficult problem, including for maintenance change requests, [15] but the request is likely to be declined if it is too expensive or infeasible. [16] If it is decided to implement the request, it can be assigned to a scheduled release and implemented. [16]
The goals of a change control procedure usually include minimal disruption to services, reduction in back-out activities, and cost-effective utilization of resources involved in implementing change. According to the Project Management Institute, change control is a "process whereby modifications to documents, deliverables, or baselines ...
Because software, unlike a major civil engineering construction project, is often easy and cheap to change after it has been constructed, a piece of custom software that fails to deliver on its objectives may sometimes be modified over time in such a way that it later succeeds—and/or business processes or end-user mindsets may change to accommodate the software.
In software development, projects and programs, a change control board (CCB) is a committee that consists of Subject Matter Experts (SME, e.g. software engineers, testing experts, etc.) and Managers (e.g. Quality Assurance managers), who decide whether to implement proposed changes to a project.

Theoretically, each change can impact the timeline and budget of a software project, and therefore by definition must include risk-benefit analysis before approval. Software configuration management is the process of identifying, and documenting the scope itself, which is the software product underway, including all sub-products and changes and ...
Software configuration management (SCM), a.k.a. software change and configuration management (SCCM), [1] is the software engineering practice of tracking and controlling changes to a software system; part of the larger cross-disciplinary field of configuration management (CM). [2] SCM includes version control and the establishment of baselines.
