As far as project management methodologies, frameworks, and guides go, the PMBOK is a must-know. But, what is the project management body of knowledge (PMBOK)? And how does PMBOK methodology work?

PMBOK stands for project management body of knowledge. It’s a meta-level look at project management—a means of gaining knowledge on scope and workflow processes and moving from project initiation to project closing.    

In this article, you’ll find all you need to know to get up to speed on PMBOK. We’ll define the term, outline PMBOK process groups and processes, and give some background and examples of the methodology. 


What is PMBOK methodology? Our definition

For a PMBOK definition, we could say that it is a guide to project management for every step of a project lifecycle, aimed to achieve a successful project outcome on schedule and within budget. 

With this said, it is important to highlight that PMBOK is not a methodology. Instead, it is a process-based framework providing the best practices for project management. As such, PMBOK can be associated with different methodologies, including the waterfall methodology and even Agile and Six Sigma methodology.

PMBOK project definition and guidelines do not include different approaches for each type of project. Precisely because of this, PMBOK is considered an instruction guide containing best practices with a general configuration.

Since PMBOK is a framework, project managers must tailor it to suit their particular project management situations. Leaving a PMBOK definition aside and thinking about practical implementation, our guide to project management body of knowledge will provide you with a few examples later on.

What does PMBOK stand for?

Once again, the acronym PMBOK stands for Project Management Body of Knowledge. 

In other words, the PMBOK meaning is that of a guide to the project management body of knowledge. It’s released by PMI as a book for managers and companies to buy, study, and apply its practices.

PMBOK history: How & when was the PMBOK approach developed?

Let’s talk briefly about the PMBOK origin story.

There once was a range of project management techniques but no central source of information on all of them. Then, in the early 1980s, PMBOK was created by the Project Management Institute (PMI), which was established in 1969. 

Recognizing the need for a standardized approach to project management, the PMI embarked on creating a comprehensive body of knowledge. The “Project Management Body of Knowledge” whitepaper was published in 1987, whereas the official PMBOK guide was issued in 1994.

This text is positioned as the project management book of knowledge. Our project management overview notes its intended status as a kind of bible on project management philosophy writ large. 

In 1999, the PMBOK Guide was recognized by ANSI, or the American National Standards Institute. Since then, PMBOK has undergone several revisions and updates to align with industry trends and emerging best practices and it is used internationally.

Seven editions have been issued until this day, and the latest one was released in 2021. The latest edition includes information on agile, adaptive, and hybrid approaches and emphasizes change-oriented project management.


The PMBOK framework explained

When it comes to the PMBOK, there is a sort of grid-like collection of lingo that you must be aware of. These are the PMBOK stages, otherwise known as process groups, and then there are the PMBOK knowledge areas.

The PMBOK is organized into knowledge areas and process groups. The knowledge areas represent the key areas of project management expertise, while the process groups represent the different phases or stages of a project.

The framework consists of 10 PMBOK knowledge areas:

  1. Project Integration Management: This knowledge area focuses on coordinating and integrating all project activities and processes.

  2. Project Scope Management: It involves defining and controlling what is included and excluded in the project scope.

  3. Project Schedule Management: This area focuses on developing and managing the project schedule, including defining activities, sequencing them, and estimating their durations.

  4. Project Cost Management: It encompasses estimating, budgeting, and controlling project costs.

  5. Project Quality Management: This knowledge area involves planning and implementing processes to ensure project deliverables meet the required quality standards.

  6. Project Resource Management: It includes acquiring, developing, and managing the project team and other resources.

  7. Project Communications Management: This area focuses on planning, managing, and distributing project information effectively.

  8. Project Risk Management: It involves identifying, analyzing, and responding to project risks to minimize their impact on project objectives.

  9. Project Procurement Management: This knowledge area covers processes related to purchasing or acquiring goods and services from external sources.

  10. Project Stakeholder Management: It involves identifying stakeholders, analyzing their interests and needs, and managing their engagement throughout the project.

The framework also defines 5 PMBOK process groups or PMBOK steps:

  1. Initiating: This group includes processes involved in defining a new project or a new phase of an ongoing project.

  2. Planning: It involves developing a comprehensive project plan, including defining objectives, creating a work breakdown structure, and outlining schedules and resources.

  3. Executing: This group focuses on coordinating and implementing project plans.

  4. Monitoring and Controlling: It entails tracking project progress, comparing it against planned objectives, and taking corrective actions as required.

  5. Closing: This process group encompasses the finalization and formal acceptance of the project.

We do understand that this might be confusing at first, so here is a table that will help you get a better overview of what we’re talking about.

Our final points on the PMBOK project management framework

The world of business is full of PMPs, or project management professionals. Today, many live and breathe by the PMBOK guide. To this effect, many great team leaders and project managers use some of the best project management software to help structure a project according to PMI’s guides in the PMBOK.

In conclusion, PMBOK is a very versatile framework that serves as a valuable resource for project management professionals, mostly because there are no project management methodologies that don’t benefit from PMI’s PMBOK guide.

However, it is important to consider the potential limitations of PMBOK, such as rigidity, complexity, and limited contextual guidance. Project managers should adapt the framework to suit their specific needs and organizational context, leveraging its strengths while addressing its weaknesses. 

By doing so, they can effectively apply the PMBOK framework and enhance their project management practices.



Is PMBOK a framework or methodology?

PMBOK is not a methodology. It is a process-based framework consisting of the best practices for project management. PMBOK provides a structured approach and guidelines for project management, encompassing knowledge areas and processes. But, it doesn’t specify a methodology or detailed steps to be followed.

Is PMBOK still relevant?

Today, the PMBOK is still quite relevant for all manners of project management. This project management body of knowledge remains relevant because it is a guide that can be applied to other project management methodologies, like six sigma, scrum, the Kanban board system, and the waterfall method.

Is PMBOK waterfall or agile?

The project management body of knowledge guide, or PMBOK guide, does not specify absolutely whether this guide is better suited as an agile project management methodology or a waterfall method. There are many project managers who would sooner classify this as a waterfall because of its clear stages.

Is PRINCE2 or PMBOK better?

There is no clear superior project management system between PRINCE2 and PMBOK. Both of these are proactive PM systems that help with planning, monitoring, and closing projects. PRINCE2 project management is a bit better than PMBOK for more clearly defining roles and responsibilities for each project team member.

What is the PMBOK guide?

The PMBOK (Project Management Body of Knowledge) guide is precisely just that - a written guide that outlines best practices and standardizes project management processes. It encompasses various knowledge areas and provides guidelines for project managers to effectively plan, execute, and control projects, improving overall project success rates.
