Project Management Body of Knowledge (PMBOK)

~ By Duncan Haughey

PMI logo

Now in its fifth edition, the Project Management Body of Knowledge (PMBOK) is a collection of processes and knowledge areas accepted as best practice for the project management profession.

As an internationally recognised standard (ANSI/PMI 99-001-2008 and IEEE 1490-2011) it provides the fundamentals of project management, irrespective of the type of project be it construction, software, engineering, automotive.

PMBOK recognises five basic process groups and ten knowledge areas typical of almost all projects. The basic concepts are applicable to projects, programmes and operations. The five basic process groups are:

  1. Initiating
  2. Planning
  3. Executing
  4. Monitoring and Controlling
  5. Closing

Processes overlap and interact throughout a project or phase. Processes are described in terms of:

  • Inputs (documents, plans, designs, etc.)
  • Tools and Techniques (mechanisms applied to inputs)
  • Outputs (documents, products, etc.)

The ten knowledge areas are:

  1. Project Integration Management
  2. Project Scope Management
  3. Project Time Management
  4. Project Cost Management
  5. Project Quality Management
  6. Project Human Resource Management
  7. Project Communications Management
  8. Project Risk Management
  9. Project Procurement Management
  10. Project Stakeholder Management (added in the 5th edition)

Each knowledge area contains some or all of the project management processes. For example, Project Procurement Management includes:

  • Plan Procurements
  • Conduct Procurements
  • Administer Procurements
  • Close Procurements

Much of PMBOK is unique to project management, for example, critical path and work breakdown structure (WBS). Some areas overlap with other management disciplines. General management also includes planning, organising, staffing, executing and controlling the operations of an organisation. Financial forecasting, organisational behaviour and planning techniques are also similar.


The Project Management Institute (PMI) is the publisher of PMBOK (now in its fifth edition) and offers two levels of certification:

A Certified Associate in Project Management (CAPM) has demonstrated a common base of knowledge and terms in the field of project management. It requires a secondary degree (high school diploma or global equivalent) and either 1500 hours of work on a project team or 23 contact hours of formal education in project management.

A Project Management Professional (PMP) has met specific education and experience requirements, has agreed to adhere to a code of professional conduct and has passed an examination designed to objectively assess and measure project management knowledge. In addition, a PMP must satisfy continuing certification requirements or lose the certification.

As of February 2012, PMI reported over 378,749 members, with 472,799 active Project Management Professionals (PMP) and 16,939 active Certified Associate in Project Managements (CAPM).¹ Over 44,000 PMP certifications expire annually; a PMP must document ongoing project management experience and education every three years to keep their certification current.

PMI is currently developing the sixth edition of the PMBOK Guide, which is expected in Q1 2017.
