Bear in mind that (a) and (b) areused primarily as internal control functions (although you maychoose to report them outside the team). Theyre used for eval-uating (c). At the risk of being repetitive, your primary focusshould always be on evaluating where you think youre goingto end up.There are two reasons for this.First, you must take intelligent and meaningful correctiveaction with the end point in mind. Guiding the ship must includemore than just steering it back on course; it must also includerecognizing that theres an object up ahead that youre going tohave to steer around or winds around the upcoming point ofland that have kicked up since you started your voyage.1/ 2Thefuture will always be different than expected at the outset of theproject. Assumptions will be revised, operating conditions willchange, and new things will be thrown in your path. Sometimes,actions you take now must compensate for future sources ofvariance as well as variances created though past performance.The second reason you need to focus on the end point per-tains to management reporting. In most cases, what will proba-bly interest them most is a prediction of where you think youregoing to end up: this is the type of information they need to runthe business. Being able to report to your management thatyoure two weeks behind schedule or $10,000 over budget rightnow may or may not be of value to them. Reporting that youexpect the project to be completed three weeks late or $15,000over budget is much more likely to be of value.Project Management 162W...。

ProjectManagement项目就是一个计划要解决的问题。
——约瑟夫. 朱兰项目是为创造独特的产品、服务或结果而进行的临时性事业。
它的特性明确且突出:· 有明确的开始时间和结束时间;(实际情况又不经常是这样,由于人们不停的要求变更,一些项目似乎永远不会结束。
)· 创造独特的产出,即以前没有做过的事情;纯粹重复性的任何事情都不能称作项目;每个项目都会涉及到以下四类关系人:· 利害关系者:在项目上有既得利益的任何人。
· 客户:项目所交付成果的使用者。
· 项目发起人:要求做某项目的人;负责确保项目获得合理的预算,进度安排是可以接受的以及团队拥有所需人员。
· 项目经理:在既定时间、预算、工作范围内,以预期的业绩水平完成项目,负全面责任的人。
同时,在项目发起人或客户中,同样存在这四类关系人,以促进项目的完成。
针对项目产生的项目管理则应运而生。
那么何为项目管理?在项目活动中应用各种知识、技能、工具和技术以达到项目要求,是通过项目管理过程—启动、计划、实施、监控和收尾—的应用与集成来实现的。
人际关系处理,使团队成员保持要求的绩效水平,对于稀缺资源的协商和谈判,政治问题的处理都是项目管理中不可量化的重要内容。
项目管理不仅仅是安排进度,不仅仅是工具,不仅仅是一个工作岗位或职位头衔,它甚至不是所有这些的总和。
项目管理是一种执行艺术,像外科手术一样,管理是一种实践,而不是一种理论;它追求的不是知识,而是绩效!管理的执行艺术只能在战壕中,像已经掌握它的人学习!在项目管理中存在四个重要变量:· 达到所要求的性能水平(Performance):桥梁必须达到特定负荷要求;汽车必须达到燃料经济性,速度等要求。
绩效规定了项目产品必须实现的功能要求;· 在成本或预算约束内(Cost):包括劳动力,设备,外购服务,材料等;· 按时(Time):项目均有时间底线;· 一定的工作范围(Scope);这四个变量之间的关系:C=f(P,T,S)不幸的是,我们永远无法知道一个项目中这些变量之间的准确函数关系,但是根据经验我们知道,如果试图改变其中一个变量,则其他三个至少会有一个发生变化。
