A software development process is a making and development process of a software program and it is popularly known as software development lifecycle process. It is also called software process, and shortly as SDLC. SDLC has several models and each of them is used for different types of tasks for different levels of activities which get incorporated in between the development process. However, there are several instances where the life cycle models are accounted as a generic term and specifically the term software development process is applied as more specific term in aspect of new implementation, renovation, and modification of existing modules related to business or for some other purpose.
In short SDLC describes different phases of software cycle and the orders in which these developmental phases are executes either in individual way or by some series of developmental ways. Although there are countless options for SDLCs these models vary from one to another but despite their discrepancies, the models maintain a great implicit similarity in between.
A general model is described by the phases it involves in its development process. The requirements are converted in different modules of designs. Different types of codes are produced at the time of implementation while it is being driven by design. Proper and methodical testing process decides the appropriateness of the designs in accordance to the proposed structure of the system and the deliverability of the designs also are judges in this developmental phase.
In nutshell the SDLC model is made of four steps like analyzing the requirements, planning the design as per the requirements, implementation of designs for the accommodation of the requirements, and then it needs proper testing of the designs and requirements in order to justify the programming and ultimate arrangements.
In SDLC designing holds a significant role; and the design is implemented from the root level of basic requirements of the development process. The focus of the developers remain high on this phase because designing phase is the foundation work of the whole developmental plan on which the whole structure of development is introduced in step-by-step format. The end product of this SDLC foundation process is communication, UML, architecture, and relevant development of hardware and software etc.
Implementation process is the second phase which comes after designing. It is one of the longest design phases in the course of SDLC. In This phase the codes are generated and thus it holds a significant role in implementing the whole process of development; however in some course, the steps are followed in automated process.
Testing is the last phase of SDLC; in this phase the balance between the requirement, designing, and coding are back-checked and verified from the point of functionality. Unit tests are used for checking specific components while system check deals with the complete system's functionality.
