The software development life cycle is a system that is used during the creation of a software program. There are a number of different models that are used, and each of them will showcase a number or procedures that can be used during the development of software. One of the most popular models used for the software development life cycle is called the CMM, or Capability Maturity Model. One of the first steps in the SDLC process is the requirement analysis. Understanding the requirements for software before you develop it is very important, and you should not begin designing the product until this is understood.
The next important part of the software development life cycle process is specification. Specification can be defined as the decision on how the software will be written. This information will often be displayed by using mathematics. Specification can be used to enhance software products that already exist, or it can be used for the creation of new software. In any event, the outer interface must be stable. After the specification process is complete, the next stage of the SDLC is called software architecture. The architecture can be defined as the hypothetical symbolism of the system. The primary objective of the architecture is to make sure the system is compatible with the product.
The architecture also deals with operating systems or hardware. Once the architecture for the system has been developed, the next stage is coding. The design for the software program must be broken down into code. Though it is one of the most important aspects of the software development process, it is not the most important. Once the code has been developed, the software must be tested. This is commonly done by software engineers, and they will look for bugs or other problems that may keep the software program from functioning correctly. Perhaps one of the most overlooked procedures of the SDLC process is documentation.
Documentation is important because it explains the design of the software, and this can be used for future modifications. When it comes to the external portion of the software, documentation is critically important, and it should not be overlooked under any circumstances. Once the software has been created, training and support must be made available for it. No matter how good the software may be in the eyes of the engineers, it is of little use if no one can use it. Most people will not bother using a software tool unless they understand how it can benefit them.
A large percentage of software programs fail to attract popular use because there is no sufficient support or training for using them. Any software company that wants to succeed in the market must not only develop high quality software tools, but they must also create high quality support and training in order to use the software. Even after the software has been built, it must undergo maintenance. An example of software maintenance is getting rid of bugs that may be present in the software.
