IS Develoment Methodology

IS Development Methodology is collection of procedure, techniques, tools, and documentation aids which will help the systems developers in their efforts to implement new IS. If we want to build a new software or an information we must refer to that particular methodology to make analysis and design process more accessible to non-expert. ISD methodologies is recommended of philosophies, phases, procedures, rules, technique for developers of information systems. There are many types of ISD methodologies to build Information Systems :

·         STRADIS

This method is introduced by Chris Gane and Trish Sarson on system analysis and design in the 1970’s. their method based on logical model, using graphical techniques to enable users. Also this method focus on flow diagram which is used to describe process in the system and how to transform data.

·         INFORMATION ENGINEERING

IE is an architectural approach to planning, analyzing, designing, and implementing application within an enterprise.

·         JACKSON SYSTEM DEVELOPMENT

JSD is is a method of system development that covers the software life cycle either directly or, by providing a framework into which more specialized techniques can fit.

·         PROTOTYPING

An easily modified and extensible model (representation, simulation or demonstration) of a planned software system, likely including its interface and input/output functionality.

·         SDLC (System Development Life Cycle)

The oldest and most known methodology used to coordinate the efforts of information systems development is known as the “Waterfall”. The model is based on a set of generic life cycle stages to guide developers from an initiating through maintenance of the completed systems.
