Software maintenance is the modification of software after delivery. [1]As per the IEEE standard glossary of software engineering terminology, software maintenance refers to the process of modifying and updating software after its initial development and deployment, to correct faults, improve performance or other attributes, add new features to meet evolving user requirements, or adapt to a ...
Model of the software development life cycle, highlighting the maintenance phase. In systems engineering, information systems and software engineering, the systems development life cycle (SDLC), also referred to as the application development life cycle, is a process for planning, creating, testing, and deploying an information system.

ISO/IEC/IEEE 12207 Systems and software engineering – Software life cycle processes [1] is an international standard for software lifecycle processes. First introduced in 1995, it aims to be a primary standard that defines all the processes required for developing and maintaining software systems, including the outcomes and/or activities of each process.
t. e. In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management.
Software asset management (SAM) is a business practice that involves managing and optimizing the purchase, deployment, maintenance, utilization, and disposal of software applications within an organization. According to ITIL, SAM is defined as “…all of the infrastructure and processes necessary for the effective management, control, and ...
v. t. e. 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 ...
Configuration management (CM) is a management process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life. [1][2] The CM process is widely used by military engineering organizations to manage changes throughout ...
t. e. Application lifecycle management (ALM) is the product lifecycle management (governance, development, and maintenance) of computer programs. It encompasses requirements management, software architecture, computer programming, software testing, software maintenance, change management, continuous integration, project management, and release ...
