Structured

Analysis

INTRODUCTION:

Structured analysis is a set of technique and graphical tools that allow the analysis to develop a new kind of system specifications that are easily understandable to the user. Analysts work primarily with their wits, pencil, and paper. Most of them have no tools. The traditional approach focuses on cost/benefit and feasibility analysis, project management, hardware and software selection and personnel considerations. In contrast structured analysis considers new goal for analysis.

The new goals specify the following:

·         Use graphical wherever possible to help communicate better with the user.

·         Differentiate between logical and physical systems.

·         Build a logical system model to familiarize the user with system characteristics and interrelationship before implementations.

The structured tools focus on the tools listed earlier – essentially the data flow diagram, data dictionary, Structured English, decision trees, and decision tables. The objective is to build a new document, called system specifications. This document provides the basis for design and implementation.
