System Dynamics-based Research On Change Management In MIS Projects

It is a common sense in consultant industry that hardly projects about developing management software system in corporations can be accomplished in planned time duration. Reason of why can be categorized into too many requirement changing, bad communication, deficient system structure and personal abilities. However, the most fundamental one is that requirements of client are always in a status of altering old ones and replacing with new ones. The unique aspect of software development projects differs from ERP implementation projects and product projects is that requirements of customers always refined and modified in the process of different phases of projects. To understand how requirement changing affect the project in the scale of whole project, and how to handle requirement changing in this kind of projects, are in fact key factors of success in this kind of projects.This thesis is trying to discuss how requirement changing affects the target of project in the sense of mechanism and causality. After analysis each token in the chain of cause and effect, we try to bring up an effective method to solve the predicament. Our proposal is to use dependency theory to re-arrange the business entities and business procedures and, based on which, to measure the effect of changing of each requirement node to build up a table containing resource super-addition of each node while changing. We also try to put up a new system technology structure which can be called"changing oriented."This thesis is mainly about:Requirement managing process and requirement change managing process we used in Shanghai Airline CRM project, and some samples of the result.Using system dynamics to analysis the mechanism of how requirement changing affect the whole project.Based on Shanghai Airline CRM project, to discuss how to re-arrange requirement network and measure the affection factor of each requirement node.To put up a"Change Oriented"technology structure.
