Each of the available methodologies is best suited to specific kinds of projects, based on various technical, organizational, project and team considerations. One system development methodology is not necessarily suitable for use by all projects. There are several different approaches to software development: some take a more structured, engineering-based approach to developing business solutions, whereas others may take a more incremental approach, where software evolves as it is developed piece-by-piece. A wide variety of such frameworks have evolved over the years, each with its own recognized strengths and weaknesses. MethodologiesĪ software development methodology (also known as a software development process, model, or life cycle) is a framework that is used to structure, plan, and control the process of developing information systems. The waterfall model is a traditional version, contrasted with the more recent innovation of agile software development. There are many approaches to software project management, known as software development life cycle models, methodologies, processes, or models. The need for better quality control of the software development process has given rise to the discipline of software engineering, which aims to apply the systematic approach exemplified in the engineering paradigm to the process of software development. System software underlies applications and the programming process itself, and is often developed separately. Embedded software development, that is, the development of embedded software such as used for controlling consumer products, requires the development process to be integrated with the development of the controlled physical product. a scientist may write software to automate a mundane task). Software can be developed for a variety of purposes, the three most common being to meet specific needs of a specific client/business (the case with custom software), to meet a perceived need of some set of potential users (the case with commercial and open source software), or for personal use (e.g. The term refers to a process of writing and maintaining the source code, but in a broader sense of the term it includes all that is involved between the conception of the desired software through to the final manifestation of the software, ideally in a planned and structured process. Therefore, software development may include research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products. Software development is the computer programming, documenting, testing, and bug fixing involved in creating and maintaining applications and frameworks involved in a software release life cycle and resulting in a software product.
