A software development process or life cycle is a structure destin on the development of a software product. Software development is primarily achieved through computer programming, which is carried out by a software programmer and includes processes such as initial research, data flow design, process flow design, flow charts, technical documentation, software testing, debugging and other software architecture techniques. This is known as the software development life cycle (SDLC).There are several models for such processes, notably the following:
An important task in creating a software program is Requirements Analysis. Customers typically have an abstract idea of what they want as an end result, but not what software should do. Skilled and experienced software engineers recognize incomplete, ambiguous, or even contradictory requirements at this point. Frequently demonstrating live code may help reduce the risk that the requirements are incorrect. Once the general requirements are gathered from the client, an analysis of the scope of the development should be determined and clearly stated. This is often called a Statement of Objectives (SOO).
Implementation is the part of the process where software engineers actually program the code for the project.
Software testing is an integral and important phase of the software development process. This part of the process ensures that defects are recognized as soon as possible. It can also provide an objective, independent view of the software to allow users to appreciate and understand the risks of software deployment. Software testing can be stated as the process of validating and verifying that a software program/application/product:
meets the requirements that guided its design and development;
works as expected; and
can be implemented with the same characteristics.
#4: Deployment and Maintenance
Deployment starts after the code is appropriately tested, approved for release, and sold or otherwise distributed into a production environment. This may involve installation, customization, testing, and possibly an extended period of evaluation. Software training and support is important, as software is only effective if it is used correctly. Maintaining and enhancing software to cope with newly discovered faults or requirements can take substantial time and effort, as missed requirements may force redesign of the software.
