Business process analysis and improvement for information system design

Abstract

The purpose of this research is to analyse and improve the business processes of the valluation company in order to deliver a design specification for information system development by using System Development Life Cycle approach. The selected methodology of this research is System Analysis and Design. It is used to plan for project, analyse current processes, find out the weak points, and design new system to fix problems. The scope of this research covers only the business processes improvement of the Valuation System which is core processes of the company. primary investigation. SWOT Analysis, Cause and Effect diagram are adopte as problem identification tools in system planning. It is found that there are improper processes and data in current processes that cause duplicated and unnecessary processes, and inconsistent and redundant data. The system is then analysed to find sources of the problems with the aid of the UML and IDEFO diagramming. From the analysis, points that need to be improved are identified. The improved processes are designed to eliminate duplicated and unnecessary processes, and inconsistent and reundant data. The newly designed system is then tested with test cases. The new design has better response to users' needs by transforming a lot of manual processes to the compute. The result of this research is a primary design specification that is fit to use for designing database, creating prototypes, and developing full-scale information system.
