Project Management Body of Knowledge

5 Categories of Processes and 9 Knowledge Domains of the Project Management Body of Knowledge

Preface: What does the theoretical project management contain? I can remember that it is a body of knowledge consisting of the three numbers. They are 5, 9 and 44. In practice, not only should the knowledge modules of project management be strengthened, but also the understanding of industry applications should be reinforced to facilitate personal growth.

The project management body of knowledge proposed by the Project Management Institute of America (PMBOK) is divided into five categories.

  1. Initiation. It refers to the formation of a project team to start a project or enter a new phase of a project. Initiation is a recognition process used to formally acknowledge the existence of a new project or a new phase.   
  2. Planning. Defining and evaluating the project objectives and choosing the best strategy for achieving them, and developing the project plan.   
  3. Execute. Mobilize resources to execute the project plan.   
  4. Control. Monitor and evaluate project deviations and take corrective action where necessary to ensure that the project plan is implemented and that project objectives are achieved.   

5) Closure. Formal acceptance of the project or phase to bring it to a procedural conclusion.

The PMBOK divides project management into nine knowledge areas.

1. Project Integration Management is also known as overall management or integrated management.  The overall project management is to properly coordinate all the components of the project and the integration of the various processes. It is a comprehensive process. At its core, it is the trade-off between multiple conflicting objectives and options in order to meet the requirements of the project stakeholders.

Note: The first article of project management is to consider the problem as a whole, which is understandable.   

2. Project scope management (Project Scope Management) is to ensure that the project is not only to complete all the provisions to do, but also just to complete the provisions to do the work. Ultimately it would be successful in achieving the purpose of the project. It is basically about defining and controlling what is or is not included in the project.

Note: Before starting the project to complete the definition of the project scope, it will involve a lot of techniques and tools.   

  • Project time management (Project Time Management) is also known as progress management. Its role is to ensure that the project is completed within the specified time.   
  • Project cost management (Project Cost Management) is also known as cost management. Project cost management is to ensure that the approved budget to complete the project within the necessary processes of the whole.   
  • Project quality management (Project Quality Management) is to ensure that the project can meet the original set of various requirements.    

Note: The three elements of project management are time, cost and quality.

  • Project Human Resource Management (Project Human Resource Management) is to ensure the most effective use of the individual capabilities of those participating in the project.   
  • Project Communications Management (Project Communications Management) is to establish links between people, ideas and information. These links are essential to success. Everyone involved in a project must be prepared to communicate in the “language” of the project and understand how their individual involvement in communication will affect the project as a whole. Project communication management is to ensure that project information is extracted, collected, disseminated, stored and ultimately disposed of in a timely and accurate manner.   
  • Project risk management (Project Risk Management) refers to the process required to identify, analyse uncertainties, and take countermeasures to these factors. Project risk management maximizes the positive results of beneficial events, and minimizes the consequences of adverse events.   
  • Project procurement management (Project Procurement Management) refers to the need to carry out the process is to obtain goods or services from outside the project organization.
