SAD 1.2(1)

There are a few System Development Methods in our syllabus. Which one is not what we learn in 1st Topic?

• Structured Analysis

• OO Analysis

• Agile Method

• Lean Method

What is Structured Analysis?

Structured Analysis is a development method that allows the analyst to understand the system and its activities in a logical way. It is a systematic approach, which uses graphical tools that analyze and refine the objectives of an existing system and develop a new system specification which can be easily understandable by user. Which terminology have you heard or read in class that relates to this method?

• Data Flow Diagram

• Business Process Modelling

• Requirements Modeling

Systems Planning produces:

• preliminary investigation report

• system requirement document

• system design specification

• functioning system

• fully operational system

Systems Analysis produces:

• preliminary investigation report

• system requirement document

• system design specification

• functioning system

• fully operational system

Systems Implementation produces:

• preliminary investigation report

• system requirement document

• system design specification

• functioning system

• fully operational system

Systems Design produces:

• preliminary investigation report

• system requirement document

• system design specification

• functioning system

• fully operational system

Systems Security and Support produces:

• preliminary investigation report

• system requirement document

• system design specification

• functioning system

• fully operational system

The purpose of this phase is to perform preliminary investigation.

• System Analysis

• System Planning

• System Implementation

• System Design

The purpose of this phase is to build a logical model of new system.

• System Analysis

• System Planning

• System Implementation

• System Design

System is ready to use in this phase, however they are not fully tested in real environment. Therefore errors normally found and programmers will have to make changes. Users may not be able to use the system, therefore in need of training. Choose the phase.

• System Security and Support

• System Planning

• System Implementation

• System Design
