Each stage in the SDLC has its own set of activities that need to be performed by the team members involved in the development project. While the process timeline will vary from project to project, the SDLC generally follows the seven stages outlined below. Many of these models are shared with the development of software, such as waterfall or agile. Numerous model frameworks can be adapted to fit into the development of software. DevOps follows the lean and agile SDLC methodologies and emphasizes collaboration.
However, there is little room for change once a phase is considered complete, as changes can affect the software’s delivery time, cost, and quality. Therefore, the model is most suitable for small software development projects, where tasks are easy to arrange and manage and requirements can be pre-defined accurately. SDLC methodologies fit within a flexibility spectrum ranging from agile to iterative to sequential. The software development lifecycle (SDLC) is a framework used to develop, deploy, and maintain software.
Start Managing Your System Development Life Cycle with a Helpful Template
All errors shall be tested after correction to ensure that they have been eliminated as part of the regression testing process and that no new ones have been introduced. A security specialist shall be appointed to provide security advice for the project—this is usually the Information Security Manager. Change management procedures for operational software are implemented.
- Software testing must take place in a specialized testing environment and should test the full functionality of the system (the test environment).
- Based on the design specifications, developers write code, create database structures, and implement necessary functionalities.
- Many of these models are shared with the development of software, such as waterfall or agile.
- In contrast, planned, linear style development can yield applications that do not meet the needs of end users even if they meet the stated requirements on paper.
- The SDLC aims to ensure that the end product is reliable, scalable, and maintainable.
- This high-risk SDLC model throws most of its resources at development and works best for small projects.

Specific focuses on the design phase, detailing how the system will be built and operate.
systems development life cycle (SDLC)
Not just limited to purely technical activities, SDLC involves process and procedure development, change management, identifying user experiences, policy/procedure development, user impact, and proper security procedures. Books such as David Avison and Guy Fitzgerald’s Information Systems Development and Alan Daniels and Don Yeates’ Basic Systems Analysis, delve into the intricacies of information systems development lifecycles. This article will provide an in-depth analysis of the history, definition, phases, benefits, and disadvantages, along with solutions that support the system development life cycle. In most use cases, a system is an IT technology such as hardware and software. Project and program managers typically take part in SDLC, along with system and software engineers, development teams and end-users. SDLC products from software vendors promise organizational clarity, modern process development procedures, legacy application strategies, and improved security features.
To help them work most effectively, development teams might adopt aspects of both the scrum and kanban agile frameworks. After the software is deployed, the software maintenance lifecycle begins. Software requires ongoing maintenance to ensure that it operates at peak performance.

This might require documenting the risk information needed to address the trust requirements in contracts, service level agreements (SLAs), or other forms of legal agreements. In fact, each organization may develop its own list of tasks, techniques, and (automated) tools, which can be referred to as “their” methodology. The basic fact finding techniques include questionnaires, interviews, observation, and document collection. With its customizable spreadsheet interface and powerful collaboration features, Smartsheet allows for streamlined project and process management. Use Smartsheet’s SDLC with Gantt template to get started quickly, and help manage the planning, development, testing, and deployment stages of system development.
