The Software Development Life Cycle (SDLC) is a process framework that describes the various phases that go through when planning, building, testing, and delivering a software application. This model is used to make software development systematic and efficient.
The SDLC has its roots in engineering sciences and was developed to manage the complexity of large software projects and improve the success rate of software developments. It offers a structured approach that ensures that all aspects of software development are considered and that the end product meets user requirements.
The SDLC is used in almost every software development project, regardless of industry or technology. It is particularly important in environments where software reliability, functionality, and maintainability are critical business factors, such as financial technology, aerospace, healthcare, and public administration.
Using SDLC offers several benefits, including higher software quality, efficient use of resources, greater control over the development process, and reduced risks through early fault detection. It also enables clearer communication between the various stakeholders.
The challenges of using SDLC include the need for thorough requirements' analysis, managing changes during the development process, and adapting to rapidly changing technologies and market conditions. A flexible approach, such as that found in agile development methods, can remedy this.
An example of how the SDLC is being used in an industrial company is the development of a digital spare parts catalog. In the planning phase, the requirements for the software are defined, followed by design, implementation, testing and finally delivery of the catalog. This structured approach ensures that the catalog has all necessary functions and is easy to use.
The Software Development Life Cycle is a crucial process framework for the systematic development of software, which helps to make the end product high-quality and compliant with user requirements. It is used across industries and helps companies develop software efficiently and minimizes risks.
