IT项目管理案例分析The GPS Auto-navigation System Verification Project戴小卫Z090309289/25/2010REQUIREMENT 1: Project OrganizationYou quickly began assembling the project planning team. The team would have responsibility for: (1) developing the project plan and schedule, (2) conducting the reliability testing of the guidance systems, (3) conducting the tear down audit and interpreting the results, and (4) reporting the results of the project to Senior Management.This is your project. Your project team consists of Gail YU, Manager of Quality Engineering, Tom HUANG, Manager of Design and Product Engineering, Jesse LIU, a senior engineer from Product Manufacturing, and Pete DONG, a senior engineer from Administration responsible for component purchasing and incoming testing of materials. Each member of your project team has access to whatever resources they need to support the project. This is a top priority for the company and you have been assured that you will “get whatever you need to complete the project”.You decide that a first order of business is to develop a Project Charter. You will have an initial meeting in one day with the project management team. This is where you will develop the project objectives, roles, and responsibilities. You decide to go in with a draft and have the team work from there.In preparation for this meeting,(a) develop an initial project charter,项目名称：导航系统可靠性测试及模块分解审计项目起始时间：2010-9-1 项目结束时间：2010-9-27项目目标：通过对5套导航系统的可靠性测试和模块审计，分别从工艺评估和工程设计分析去判断那些工艺上的缺陷对产品的影响。
通过测试结果的说明去说服客户公司的产品设计和实现是可靠可信的。
项目经理：Da i xiaowei Reliability Engineering Manager项目成员：Gail YU， Manager of Quality EngineeringTom HUANG，Manager of Design and Product EngineeringJesse LIU，senior engineer from Product ManufacturingPete DONG，senior engineer from Administration responsible for componentpurchasing and incoming testing of materials项目进程安排：1. 设计测试计划和时间安排2. 实施导航系统可靠性测试3. 实施模块分解审计，说明审计结果4. 分析测试和审计结果5. 提交项目总结报告(b) develop a complete Linear Responsibility Chart,2 - Supervision3 - Must be consulted4 - May be consulted5 - Must be notified6 - Approval authority(c) complete a stakeholder analysis.REQUIREMENT 2: Network Planning for the Reliability Testing and Workmanship AuditingThe team has quickly developed a sequence of major activities for the project. These activities are listed in the table below along with durations and predecessor relationships:Given the table of project activities:(a)Develop a CPM Activity on Node diagram for the project,Determine the critical path and the duration of the critical path for the project,CPM为AKMN，总项目时间为21天。
(c), What conclusions can you draw from the CPM diagram?,从定义出的关键路径可以看出，整个项目的主要工作量和成本集中在可靠性测试中，只有保证可靠性测试按时完成，整个项目才不会出现延误，通过追踪关键路径可以平衡整个项目的进度。
(b)Discuss the assumptions, limitations, and implications for using the CPM as an approach forscheduling this project?由于该项目对成本并无要求，但是对时间和资源都有比较严格的控制要求，可以通过关键路径法对项目进度和项目所需资源进行优化，同时由于关键路径法本身的缺点所导致的局限性，诸如：各个活动的优先级并不明显，各个活动的时间经常需要利用概率分布来估计时间点，有可能会出现偏差，如果遇到确实无法确定的工作，管理团队应该在项目运作中进行充分的分析并做出相应的调整，此时的网络计划就显得非常无力。
REQUIREMENT 3: PERT as a method to schedule the ProjectYou want to develop a more realistic estimate for the project schedule. Therefore, you have requested that your project team develop PERT based estimates for project durations. The following table has been provided with the PERT data:Given the table of project activities:(a)Develop a PERT Activity on Node diagram for the project (This diagram must specify thecritical path and duration of the CP,通过PERT分析的关键路径可知完成整个项目可能需要24个工作日(b)Construct a table which identifies: Activity, duration, Early Start, Early Finish, Late Start,(c)What can you conclude about the project duration from analysis of the PERT networkdiagram?,通过PERT分析关键路径我们可知对于分解模块审计决定了整个项目的进程。
因此如果能够控制对分解模块审计的时间就可以有效地缩短整个项目所需要的时间(d)What are the primary concerns that a PM must consider in using PERT for projectscheduling?利用PERT进行项目管理调度主要考虑时间的不确定性，重点在于对时间的控制，在已知乐观时间，悲观时间和最可能时间的前提下，通过公式计算出期望时间最后确定关键路径。
REQUIREMENT 4: Risk ManagementJames TAN is concerned about the failure in the project. There is a great deal at stake for the company, not to mention his career. He approaches you and says that he heard that, “Risk Management is an approach that can totally el iminate project failure.” Based on your knowledge of risk management and the case situation:(a)discuss the statement made by James TAN,James Tan的论断是不全面的。
风险管理的主要目的是在项目管理过程中识别风险和控制风险。
通过对风险的转移、防范、避免、降低和利用五种策略可以有效的进行风险管理。
在任何项目中都存在着风险，风险是一种不确定性，风险可能会导致项目的失败，有效的风险管理可以降低这种可能性。
