IS DEVELOPMENT MENTHODHOLOGIES (ISD)

1. DEFINITION:

ISD methodologies is a collection of procedures, techniques, tools and documentation aids which will help the systems developers in their efforts to implement a new information system.

There are many different methodologies used in systems development

A methodology is a collection of:

Procedures

Tools                                                     which will help the systems developers to implement a new information system

Documentation aids

2. PARTICIPANT IN SYSTEMS DEVELOPMENT:

- Project manager.

- Stakeholders ( anyone who involve environment).

- Users.

- System analyst (facilitytater).

- Programmers ( design the program).

- Support personnel.

3. STEPS IN ISD PLANNING:

strategic plans --> develop objective --> identify IS project -->  analyze resources --> set schedule and deadlines --> develop IS

4. TYPES OF ISD METHODHOLOGIES:

a) Game and Sarsors (Stradis)

b) Stages

initial study ( identify the system) -> detail ( get the data from ISD and dentify the data)-> designing alternatives -> physical design ( jobs of programmer to design the systems)

c) Information Engieneer (IE)

d) Prototyping

Determine requirement -> analyze alternative -> specify design->implement design -> user review-> 

e) Structured approach (SDLC)

System investgation -> system analysis -> system design -> system implementation -. system Mainternance and review.
