Much of knowledge and many of the tools and techniques for managing project are
unique to project management, such as work breakdown structure, critical path
analysis, and earned value management. However, understanding and applying the knowledge, skills, tools and techniques, which are generally recognized as a good practice, are not sufficient alone for effective project management.

- The project management body of knowledge
- Application area knowledge – regional space
- Understanding project environment
- General management knowledge and skills
- Interpersonal skill
