The System Development life Cycle (SDLC) is a conceptual model used in project management that describes the stages involved in an information system development project from an initial feasibility study through maintenance of the completed application. Various SDLC methodologies have been developed to guide the process involved including the waterfall model (the original SDLC method), rapid application development (RAD), joint application development (JAD), and the fountain model and spiral model.

 

Description

 A Systems Development Life Cycle (SDLC) has three primary objectives: ensure that high quality systems are delivered, provide strong management controls over the projects, and maximize the productivity of the systems staff. In order to meet these objectives the SDLC has many specific requirements it must meet, including being able to support projects and systems of various scopes and types, supporting all of the technical activities, supporting all management activities, being highly useable, and providing guidance on how to install it.

 

The technical activities include: system definition (analysis, design, coding), testing, system installation, production support. The management activities include: setting priorities, defining objectives, project tracking and status reporting, change control, risk assessment etc

 

SYSTEM LIFE CYCLE

System Life cycle is an organization process of developing and maintaining systems. It helps in establishing a system project plan, because it gives overall list of processes and sub processes required for system developing.

STAGES OF SYSTEM DEVELOPMENT LIFE CYCLE

The following are the different stages of system development life cycle

I.            Preliminary study

II.            Feasibility study

III.            Detailed system study/ Investigation study

IV.            System analysis

V.            System design

VI.            Implementation

VII.            Maintenance

VIII.            Study review

 

1.                 Revision on examination questions

Student are allowed to give corrections to the assessment given by the teacher, while the teacher support s them in order to guide them

 

Assignment

1.      Make an online research about the different stages, to be discussed by students next class.
