说明：  项目管理知识体系指南 项目管理知识体系（PMBOK）是描述项目管理专业知识的专业术语。正如法律、医药和会计等其它专业 一样，这一知识体系的发展依赖于那些实践者和学者们对它的应用和提高。整个项目管理知识体系不仅包 括那些通过实践检验并得到广泛应用的传统方法和知识，还包括经过一些应用但具有创造性的知识和先进 方法；不仅包括已出版的资料，而且还包括未出版的资料。
(The Project Management Body of Knowledge (PMBOK© ) is an inclusive term that describes the sum of knowledge within the profession of project management. As with other professions such as law, medicine, and accounting, the body of knowledge rests with the practitioners and academics that apply and advance it. The full project management body of knowledge includes knowledge of proven traditional practices that are widely applied, as well as knowledge of innovative and advanced practices that have seen more limited use, and includes both published and unpublished material.)
