If you’ve ever heard of the software development life cycle (SDLC), you’ve probably asked yourself: What is SDLC? Essentially, this is a process for developing software systems. During the software development phase, business analysts meet with clients to gather requirements. Afterward, they create a business requirement specification (BRS), which provides guidelines for the other phases of the SDLC. BRSs also define a system’s technical, legal, and economic feasibility.
The main purpose of the SDLC is to produce a high-quality product that thetotal meets the requirements of the client. It includes the phases of requirement gathering, design, coding, testing, and maintenance. The entire software development lifecycle is designed to help developers avoid the typical pitfalls of software development projects. The various phases in the SDLC allow the development team to work on every feature and document in a systematic manner.
After the development stage, evaluation is the next phase. Although not an official stage of SDLC, some companies view evaluation as an extension of the maintenance stage. In either case, it evaluates the newly implemented system to ensure that it meets its intended objectives. Evaluations can be used to ensure that the software meets its intended requirements and is reliable and fault-tolerant. They can also be used to assess the development process itself. When all four phases have been completed, the project can go to the installation stage.
The first stage is the design phase. In this phase, architectural modules are defined, as is the data flow representation and communication between modules. The DDS should also include the internal design of all modules. Once the DDS is complete, actual development can begin. During this phase, programming code is generated based on the DDS. With detailed design, code generation is simple. However, it is important to use effective communication and alignment across the project team.
