REQUIREMENT 1: Project Organization
You 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 Engineering
Tom HUANG,Manager of Design and Product Engineering
Jesse LIU,senior engineer from Product Manufacturing
Pete DONG,senior engineer from Administration responsible for component
purchasing 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 - Supervision
3 - Must be consulted
4 - May be consulted
5 - Must be notified
6 - Approval authority
(c) complete a stakeholder analysis.
REQUIREMENT 2: Network Planning for the Reliability Testing and Workmanship Auditing
The 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 for
scheduling 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。
