System Development Life Cycle

Introduction System development methodologies are promoted as a means of improving the management and control of the software development process, structuring and simplifying the process, and standardizing the development process and product by specifying activities to be done and techniques to be used. It is often tacitly assumed that the use of a system development methodology will improve system development productivity and quality. However, there is little empirical evidence to support this assumption. As we know that, Information System (IS) refers to a system of people, data records and activities that process the data and information in an organization, and it is includes the organization's manual and also the automated processes.
Here all the development of IS are referring to the useful of standard selection of system development methodology. There are various types of information systems which successful implementation for the end users, for example: transaction processing systems, decision support systems, knowledge management systems, database management systems, registration system, payroll system, inventory system and office information systems. There are numerous types of system development methodologies such as AGILE, System Development Life Cycle (SDLC), Prototyping, Rapid Application Development (RAD), Joint Application Development (JAD), Computer Aided Software Engineering (CASE), Object Oriented or others.

System Development Life Cycle (SDLC) SDLC stands for Software Development Life Cycle. A Software Development Life Cycle is essentially a series of steps, or phases, that provide a model for the development and lifecycle management of an application or piece of software. The methodology within the SDLC process can vary across industries and organizations, but standards such as ISO/IEC 12207 represent processes that establish a lifecycle for software, and provide a mode for the development, acquisition, and configuration of
