How many processes are defined by PMI's PM-BOK guideline ?

There are47 processes ,10 knowledge areas and5 process groups are outlined below.

47 project processes grouped by knowledge area

47 processes grouped by Process Group

That was a nice one Alex, thanks for the reply.

But, according to the5th edition they have added "Stakeholders Management" knowledge area.

Moreover, the answer was related to the knowledge areas. I'm really asking about the total processes number.

Thanks for your interaction

There are Nine PMBOK Guide project management knowledge areas, that are used throughout the project management processes.

They are:

• Project Integration management
• Project Scope management
• Project Time management
• Project Cost management
• Project Quality management
• Project Human resource management
• Project Communications management
• Project Risk management
• Project Procurement management

The Guide recognizes47 processes that fall into five basic process groups and ten knowledge areas that are typical of most projects, most of the time.

Process groups

The five process groups are:

1. Initiating : Those processes performed to define a new project or a new phase of an existing project by obtaining authorization to start the project or phase.
2. Planning : Those processes required to establish the scope of the project, refine the objectives, and define the course of action required to attain the objectives that the project was undertaken to achieve.
3. Executing : Those processes performed to complete the work defined in the project management plan to satisfy the project specifications
4. Monitoring and Controlling : Those processes required to track, review, and regulate the progress and performance of the project; identify any areas in which changes to the plan are required; and initiate the corresponding changes.
5. Closing : Those processes performed to finalize all activities across all Process Groups to formally close the project or phase.

Knowledge areas

The ten knowledge areas are:

1. Project Integration Management : Project Integration Management includes the processes and activities needed to identify, define, combine, unify, and coordinate the various processes and project management activities within the Project Management Process Groups.
2. Project Scope Management : Project Scope Management includes the processes required to ensure that the project includes all the work required, and only the work required, to complete the project successfully.
3. Project Time Management : Project Time Management includes the processes required to manage the timely completion of the project.
4. Project Cost Management : Project Cost Management includes the processes involved in planning, estimating, budgeting, financing, funding, managing, and controlling costs so that the project can be completed within the approved budget.
5. Project Quality Management : Project Quality Management includes the processes and activities of the performing organization that determine quality policies, objectives, and responsibilities so that the project will satisfy the needs for which it was undertaken.
6. Project Human Resource Management : Project Human Resource Management includes the processes that organize, manage, and lead the project team.
7. Project Communications Management : Project Communications Management includes the processes that are required to ensure timely and appropriate planning, collection, creation, distribution, storage, retrieval, management, control, monitoring, and the ultimate disposition of project information.
8. Project Risk Management : Project Risk Management includes the processes of conducting risk management planning, identification, analysis, response planning, and controlling risk on a project.
9. Project Procurement Management : Project Procurement Management includes the processes necessary to purchase or acquire products, services, or results needed from outside the project team
10. Project Stakeholders Management : Project Stakeholder Management includes the processes required to identify all people or organizations impacted by the project, analyzing stakeholder expectations and impact on the project, and developing appropriate management strategies for effectively engaging stakeholders in project decisions and execution.

Each of the ten knowledge areas contains the processes that need to be accomplished within its discipline in order to achieve effective project management. Each of these processes also falls into one of the five process groups, creating a matrix structure such that every process can be related to one knowledge area and one process group.
