PMBOK Guide 笔记一

Purpose of the PMBOK® Guide

The primary purpose of the PMBOK® Guide is to identify that subset of the Project
Management Body of Knowledge that is generally recognized as good practice.
“Identify” means to provide a general overview as opposed to an exhaustive
description. “Generally recognized” means that the knowledge and practices
described are applicable to most projects most of the time, and that there is
widespread consensus about their value and usefulness. “Good practice” means that
there is general agreement that the correct application of these skills, tools, and
techniques can enhance the chances of success over a wide range of different
projects. Good practice does not mean that the knowledge described should always
be applied uniformly on all projects; the project management team is responsible
for determining what is appropriate for any given project.

本指南的目的

本指南的基本目的是识别项目管理知识体系普遍公认为良好做法的那一部分。识别，指一般概括性介绍，而非详尽无遗的说明。普遍公认，指介绍的知识和做法在绝大多数情况下适用于绝大多数的项目，其价值和实用性也得到了人们的广泛认同。最佳实践，指一致认为，正确应用这些技能、工具和技术能够增加范围极为广泛的各种不同项目成功的机会。最佳实践并不是说这些知识和做法一成不变地应用于或应当应用于所有的项目；对任何一个指定的项目，项目管理团队负责决定体系中的哪些东西适用。

What is a Project?

1.2.1 Project Characteristics
A project is a temporary endeavor undertaken to create a unique product, service, or
result.

1 . 2 什么是项目
1 . 2 . 1 项目的特征
项目是为提供某项独特产品、服务或成果所做的临时性努力。

1 Temporary
Temporary means that every project has a definite beginning and a definite end. The
end is reached when the project’s objectives have been achieved, or it becomes clear
that the project objectives will not or cannot be met, or the need for the project no
longer exists and the project is terminated. Temporary does not necessarily mean
short in duration; many projects last for several years. In every case, however, the
duration of a project is finite. Projects are not ongoing efforts.

1 临时性
临时性是指每一个项目都有确定的开始和结束，当项目的目的已经达到，或者已经清楚地看到该目的不会或不可能达到时，或者该项目的必要性已不复存在并已终止时，该项目即达到了它的终点。临时性不一定意味着时间短，许多项目都要延续好几年。然而，在任何情况下项目的期限都是有限的，项目不是持续不断的努力。

2 Unique Products, Services, or Results
A project creates unique deliverables, which are products, services, or results.

2 独特的产品、服务或成果
项目创造独特的可交付成果，如产品、服务或成果。项目可以创造：生产出来可以量化的产品或制品，既可以本身就是最终物件，也可以是其他物件的组成部分。

3 Progressive Elaboration
Progressive elaboration is a characteristic of projects that accompanies the concepts
of temporary and unique. Progressive elaboration means developing in steps, and
continuing by increments1. For example, the project scope will be broadly described
early in the project and made more explicit and detailed as the project team develops
a better and more complete understanding of the objectives and deliverables.
Progressive elaboration should not be confused with scope creep

Progressive elaboration of a project’s specifications needs to be carefully
coordinated with proper project scope definition, particularly if the project is
performed under contract. When properly defined, the scope of the project—the
work to be done—should be controlled as the project and product specifications are
progressively elaborated. The relationship between product scope and project scope
is discussed further in the Chapter 5 introductory material.

 3 逐步完善
逐步完善是项目伴随临时性和独特性两个概念的特点之一。逐步完善意味着分步、连续的积累’。例如，在项目的早期项目范围的说明是粗略的，随着项目团队对目标和可交付成果的理解更完整和深入时，项目的范围也就更具体和详细。请勿将逐步完善与范围潜变混淆（见55 节）。
项目产品技术要求说明书的逐步完善务必要与项目范围的恰当定义谨慎地协调起来，在项目是按合同实施时，尤其应当如此。如果项目范围即需要完成的任务，规定得恰如其分，则即便是在产品技术要求说明书的逐步完善过程中，项目范围仍应保持控制状态。第5 章的引言将进一步讨论产品范围与项目范围之间的关系。

What is Project Management?

Project management is the application of knowledge, skills, tools and techniques to
project activities to meet project requirements. Project management is accomplished
through the application and integration of the project management processes of
initiating, planning, executing, monitoring and controlling, and closing. The project
manager is the person responsible for accomplishing the project objectives.
Managing a project includes:
   • Identifying requirements
   • Establishing clear and achievable objectives
   • Balancing the competing demands for quality, scope, time and cost
   • Adapting the specifications, plans, and approach to the different concerns and
     expectations of the various stakeholders.
Project managers often talk of a “triple constraint”—project scope, time and
cost—in managing competing project requirements. Project quality is affected by
balancing these three factors (Chapters 5 through 7). High quality projects deliver the
required product, service or result within scope, on time, and within budget. The
relationship among these factors is such that if any one of the three factors changes,
at least one other factor is likely to be affected. Project managers also manage
projects in response to uncertainty. Project risk is an uncertain event or condition
that, if it occurs, has a positive or negative effect on at least one project objective.

1 . 3 什么是项目管理
项目管理就是把各种知识、技能、手段和技术应用于项目活动之中，以达到项目的要求。项目管理是通过应用和综合诸如启动、规划、实施、监控和收尾等项目管理过程来进行的。项目经理是负责实现项目目标的个人。管理一个项目包括：
    识别要求；
    确定清楚而又能够实现的目标；
    权衡质量、范围、时间和费用方面互不相让的要求；
    使技术规定说明书、计划和方法适合于各种各样利害关系者的不同需求与期望。
项目经理经常提到，在出现管理互不相让的要求时遇到的项目范围、时间和费用“三重制约”的问题。项目的质量受这三个因素权衡的不利影响（第5 章一第7 章）。高质量的项目能在预算内按时提交满足要求的产品、服务或成果。上述因素之间的关系是，如果三个因素之一发生了变化，其他因素中至少有一个会受到影响。项目经理还根据不确定性来管理项目。项目风险是一旦发生至少会积极或消极影响一个项目目标的不确定事件或条件。
