Requirements Change Management In Dongfang Container Leasing Information System Project Development

Software requirement is the basis of software programming and relevant project management.Requirements management is requisite for project construction,and requirements change is the key task in requirements management.Integrating requirements change into CMMI would make requirements change present itself with CMMI structure,rather than staying at a single level,which make it possible for the management of requirements change to perform in a more systematic,comprehensive and standardized manner.This article defines the requirements change management of information system based on CMMI.In light of the research findings summarized from both domestic and international literature and journals,the article puts forward the notion that requirements change management should run through the entire process of the project,based on which it further discusses the management and strategy for improvement of requirements change control.The article subject is the Dongfang container leasing information system.The feature of container leasing business is analyzed through such perspectives as business requirements,business flow and change problem,etc.Which helps to understand the importance of requirements change management.Then based on CMMI,the article discusses the requirements change management of container leasing information system from such perspectives as the process of requirements management,requirements change reason,requirements change control process and requirements change control improvement.Finally,combined with the empirical method,the application of rapid prototyping method,demand tracking matrix of three analysis methods of fishbone diagram,and combined with the requirements change control combination of control flow change committee and demand,and puts forward the process of requirements change control improvement measures,and carry out the effect evaluation and analysis.This article will provide theoretical basis for project management personnel to practice requirements change management,which will enhance the understanding of risk in requirements change arising in the process of large-scale information system project construction,and methodology that accommodates requirements change management of large-scale information system project can be worked out accordingly.
