Traditional project management methods are often insufficient for the present-day uncertain and resource-constrained project management landscape. This is where critical chain project management comes into play. In contrast to other methodologies, this project management tool helps optimize resource utilization, reduce bottlenecks, and address uncertainties

The article explores the essence of CCPM methodology, outlines its benefits and stages, and provides insight into the capabilities of project management software based on CCPM principles.

Defining the Basics: What Is Critical Chain Project Management?

Critical chain project management is an indispensable framework for minimizing the risks of time and budget overruns. Initially, the framework was based on the theory of constraints, which views organizations as entities where their weakest part can negatively impact overall outcomes. Currently, this method stands as a solution to the challenges of resource constraints and task estimation. In contrast to other existing methodologies (e.g., Critical Path), the Critical Chain, as a new approach to project management, considers the scarcity of available resources to identify the critical set of tasks and the timeline needed for project completion. 

As a result, the CCPM method helps managers avoid bottlenecks, which distinguishes it from traditional approaches. 

How Is the Critical Path Viewed in Critical Chain Project Management?

Critical chain project management still implements the Critical Path method in scheduling a project. The Critical Path method outlines the longest path of dependent tasks that dictates the minimum project duration. In turn, critical chain project management optimizes this model by adding buffers and considering resource limitations, thereby avoiding disruptions caused by constraints.

Core Components of the Critical Chain Method

The reason why previously developed methodologies failed to deliver the desired results is their theoretical limitations that implied an unlimited number of resources in addition to a static environment. In contrast, the CCPM method includes the following components to overcome this issue:

  • The Critical Path: This component allows project managers to estimate task dependencies by outlining their main level. If a task does not affect the critical path, it creates the next component known as the Feeding Chain. 
  • The Feeding Chain: This element of the scheduled project’s model is a concurrent task with the critical path, which eventually merges with this component. It is crucial to admit that tasks must be executed at the same time as the critical path to prevent bottlenecks or delays. 
  • Buffers: these elements can be categorized into time, labor, and materials necessary to create a room for maneuver in case of unexpected changes affecting project and task execution. For example, it can be an additional time to minimize risks of delays between the feeding chain and critical path, while additional materials or labor can be used in case of supply shortage.  

Now, let’s consider the significance of CCPM for seamless project management.

What Are the Benefits of Critical Chain Project Management?

The application of Critical Chain project management addresses the key challenges that cannot be handled by traditional project management approaches. They include:

  • Project delays, missing the originally planned due date.
  • A lack of required resources at the right time.
  • Budget overruns and the need for extra costs for completing the project.

The Critical Chain framework helps not only to address the above-mentioned challenges but also strengthens organizational performance. Let’s consider additional benefits of adopting this approach to managing projects. 

1. Preventing project delays. 

Uncertainties and risks can disrupt the task completion, which can undermine the project’s success. Buffers, in turn, are designed to prevent delays by adding time and resources: effective buffer planning can boost performance and reduce the project’s duration. 

2. Improved delivery rates. 

You can significantly improve the delivery rates by prioritizing throughput that centers on the project’s flow. By eliminating multitasking and task padding, team members can focus on the highest-priority tasks (that are in the Critical Path), be more productive, and complete their work even earlier. The absence of task buffers provides an opportunity to complete the project even earlier. 

3. The opportunity to take more projects. 

The adoption of the Critical Chain method in project management enhances the ability to complete more projects within a given timeframe. This approach combines buffers, resource synchronization, and project staggering to achieve this outcome. It also means that project managers can improve overall throughput across projects.

Now that the essence and importance of this project management methodology are clear, let’s consider the process itself.

Main Stages of the Critical Chain Project Management Process

1. Identifying the Critical Path. 

The Critical Chain method in project management starts with critical path identification to plan the next stages. It is comparable to creating the foundation of the entire project, which outlines the interdependent tasks that set up the core of the future processes. Therefore, the first step is to consider the most important tasks in addition to the longest to complete. 

2. Detecting resource constraints.

Identifying resource constraints is a necessary component of creating the Critical Chain. Project management critical chain involves considering all possible constraints for every task (the number of people assigned to tasks, materials or equipment, and workspace). 

3. “As Late As Possible” scheduling.

This step requires scheduling tasks backward from the due date through each task, starting on the latest possible start date. This approach differs from starting a new task as early as possible. This type of scheduling prevents multitasking with its negative consequences. 

4. Adding buffers. 

Based on the drafted Critical Chain, project managers should add the necessary buffers in addition to feeding chains. Risk assessment is also necessary to determine the necessary amount of buffer: higher risks require a bigger buffer to avoid disruptions. 

5. Project execution and monitoring. 

It’s important to focus on one task at a time to avoid multitasking. Project monitoring should be based on buffer consumption using Fever Charts. Buffer consumption will provide you with insight into the project’s health and help you identify issues early on.

Critical chain project management software helps project managers to plan and schedule projects, allocate resources, and track progress in real-time. Let’s consider their role in more detail.

Reasons to Acquire Critical Chain Project Management Software 

Critical Chain Project Management (CCPM) software provides an opportunity to reap the benefits of the CCPM method: it simplifies its implementation by automating some processes and providing real-time insights. Here are the other benefits provided by CCPM software.

  • Automated buffer management: As a rule, CCPM has graphs or charts (e.g., Fever Chart) that help project managers visualize buffer consumption and assess project health at a glance.
  • Optimized resource allocation and management: CCPM software monitors resource availability and capacity, which helps avoid resource bottlenecks and project delays caused by a lack of required resources.
  • Improved decision-making: CCPM tools provide various real-time data, dashboards, reports, and forecasts, which help managers make better decisions.
  • Comprehensive visibility into project processes: PM software provides project managers with a big picture of the state of the whole project environment, project progress, resource performance, etc. 

An example of software based on CCPM principles is Epicflow. It simplifies complex multi-project and resource management by smart prioritization based on buffer consumption, intelligent resource allocation, comprehensive buffer management, and overall control of the project environment, and AI-powered informed decision-making.
