System Development Life Cycle Variation

Variations of the Phases (Waterfalls Models)

Waterfall Model – each life model is completed in sequence and then the results of the phase flow on the next phase. There is no going back once a phase is completed.

Iteration across Life Cycle Models

Iteration means that the work tasks are done once, then again, and yet again.

Spiral Cycle Model – Life cycle model with heavy iteration that breaks each project into smaller pieces, each a different type of risk

Socio Technical Systems – Information systems that include both social and technical subsystems designed to work well together

Rapid application Development (RAD) - a variation of the system development life cycle that aims to speed up radically the development process using a variety of techniques.

Systems Development Life Cycle – A method of systems development that consists of planning, analysis, design, implementation, and support phases

Project – a planned undertaking that has a beginning and an end and which produces a predetermined result or product

Phase – a division of the SDLC in which similar activities are performed

Phases of Systems Development Life Cycle
1. Planning phase – The initial phase of the SDLC whose objective is to scope and plan the project Four activities in the Project planning phase
i. Define the problem
ii. Confirm project feasibility
iii. staff the project
iv. launch the project
2. Analysis Phase – one phase of SDLC whose objective is to understand the user’s needs and develop requirements Six primary activities in analysis phase
i. gather information
ii. define system requirements
iii. build prototypes for discovery of requirements iv. prioritize...
