Comprehensive Camp System Maintenance, Project Management Applied Research

The telecommunication billing system is a huge systems engineering, its construction and the running Maintenance work, must depend upon the science, high quality and the high efficiency management can realize. The former telecommunication profession has used the pattern which to the billing system maintenance oneself develop itself to maintain, along with the service and number of users explosion, the self-sufficient maintenance pattern already could not satisfy the fast expansion the telecommunication market need. Therefore, uses the service outsourcing to become the telecommunication billing system maintenance's mainstream pattern. After how to enhance the service outsourcing, the systematic maintenance level has become the telecommunication profession universal attention the focal point question, this article based on this goal, how explores the application project management theory and the method realizes to the Sichuan Netcom billing system maintenance work management.This article analyzes the Sichuan Netcom billing system maintenance work's characteristic, the present situation and the existence question, applying the project management theory and the method, has carried on a more comprehensive summary and the research to the series maintenance work, how apply to the company application project management theory solution system maintenance work's question to propose uses for reference suggestion.In the article first through the massive literature search, has carried on the analysis to the Sichuan Netcom billing system maintenance work existence's question, proposed solves the question main mentality with the project management theory; And makes concrete from the communication management, the requirements management, schedule management and the quality control four aspects carries on the analysis and the research..The communication management aspect, this article has analyzed in the Sichuan Netcom billing system maintenance work communication present situation thoroughly, and unifies the system maintenance work the actual situation, the application project management communication theory, proposed that is suitable in the system maintenance work communication present situation model and the method;The requirements management aspect, this article has analyzed the system maintenance work characteristic, applies WBS the method, carries on the decomposition to the demand scope, the formulation demand scope plan, the definition project demand scope, the checking control project scope, proposes the corresponding management to the project demand scope change;Schedule management aspect, carries on the example analysis in view of the system maintenance work's in some demand duty, the utilization essential chart law definite duty time, carries on the progress control using the by-way chart law, uses the optimized control method to carry on the regulation to the progress, proposed suits in the system maintenance work schedule management model;The quality control aspect, based on the company quality control system, the union quality control theory, carries on the analysis to the system maintenance work's quality control system, summarizes suits this system characteristic the quality control system.The present paper research results have made some exploring endeavor to the system maintenance work in the fundamental research aspect, simultaneously also has certain reference significance to other IT system's maintenance work.
