The Control Research For The Development Project Progress Of ZTE Optical Fiber Communication Product

With the gradual progress of the triple-play and China's broadband project,the operators and the radio and television system will have a great demand of optical fiber communication devices.To meet the huge market demand,manufacturers are accelerating the progress of developing new products,in order to launch new products faster with occupying more market and making more profits.And as a progress of developing new products,the project operation can effectively shorten the length of time for developing products,meanwhile,ensure products' quality and reduce costs.This article takes new optical fiber communication products C320 of ZTE company as object,simply illustrates the definition of this project and the contents of project management.The way of developing C320 is to use project operation,divides all works in developing C200 projects through work breakdown structure into 5 steps,then subdivides each step into single actives.After confirming the logical relationship among actives,with estimating the length of time for each projects through analogy method and Delphi method,we draw a product development project's Cuntt chart by using MSProject2010 according to time.Then we calculate the whole cycle of C320 product development pro ject cycle and find out the Critical Path to this project and introduce resource constraints.Firstly,we find out Critical Chains of activities by Critical Chain project management(CCPM),then use the improved 1 / 2 buffer rule to optimize activity du ration,adjust the activities finally make the developing project scheduling with the project buffer(PB).In the implementation of research and development projects of optical fiber communication products C320,we use project scheduling plans worked out by Chapter 3 to organize teams,provide training to improve stuff members' abilities,optimize decision progress and risk management in the whole progress.We complete all the actives in advance.Comparing with the plan of our company,we publish the products 4 months earlier than the rivals,which win more time for further marketing promotion.Through the understanding and application of Theory of Constraint(TOC),it can be used for reference and application of the progresses in controlling other software and hardware integration.
