A8-R5-Systems Analysis, Design and Testing

A8-R5-Systems Analysis, Design and Testing

Introduction

The module is designed to equip a person to understand System Analysis and Design aspects. It provides theoretical background as well as in depth knowledge through case studies. This module covers both structured and Object-oriented techniques to analyse and design software.

Objective

After completing the module, the incumbent will be able to:

i. Under the need of system analysis and design in software development

ii. Understand complete life cycle of System analysis and Design

iii. Do the feasibility analysis and design of the proposed system

iv. Use various analysis and design tools and techniques

v. Get familiar with Object oriented System Design

vi. Understand the role of testing in software developmentLearning Objectives(Learner will learn after completion of unit)
