## Application of the Critical Path Method in Project Management

# Introduction

Every project involves multiple tasks, some of which are interdependent. Consequently, certain tasks influence the completion of others. Critical tasks must be under continuous control. Managing this workload requires significant effort, meticulous planning, and adherence to pre-established deadlines. For startups and venture capital firms leveraging tools like Co-Founder Ai, implementing structured project management methodologies such as the Critical Path Method can significantly enhance efficiency and success rates.

# Critical Path Method: What Is It?

The Critical Path Method (CPM) is a planning algorithm that enables precise scheduling of project implementation, particularly for projects with long chains of interrelated tasks known as critical chains. In today’s competitive landscape, CPM is one of the most sought-after methods in project management, often utilized within PERT analyses as a component of comprehensive project evaluations.

Achieving the necessary calculation accuracy is possible through simplifying the critical chain—breaking it down into its constituent parts. This process, known as decomposition, is a topic for comprehensive independent study and is essential for startups aiming to optimize their project timelines and resource allocation.

# History of the Critical Path

The Critical Path Method was first introduced by American economists M. R. Walker and J. E. Kelly Jr. in the late 1950s. Representing major corporations such as DuPont and Remington Rand, their work was primarily practical in nature, focusing on improving project planning and execution within large enterprises.

During this period, DuPont acquired one of the first computers, the UNIVAC1, and sought ways to apply it to enhance the company’s operational efficiency. The primary focus was on planning, assessment, and schedule formation. M. Walker was tasked with determining whether the machine could be programmed to perform these tasks effectively.

After several months of project work, with the main criterion being the balance of time and cost, a solution was proposed to concentrate efforts on “critical” tasks. This approach not only allowed for a reduction in project completion time but also helped prevent significant cost increases. The remaining task was to identify the “critical” tasks from the overall workload.

It’s worth noting that similar methodologies had been previously utilized by DuPont and in the development of nuclear weapons in the United States. However, the project did not see practical implementation due to the high complexity of its execution with the technology of the time—the UNIVAC1 required approximately 350 working hours to perform the calculations. The project was subsequently terminated due to a lack of further prospects.

In 1959, one of the first CRM projects was revived by Mauchly & Associates, intending to commercialize it by focusing on optimizing time expenditures. Later, the method gained widespread adoption in project planning across various industries, including construction, IT, weapons production, and large-scale industrial design, proving its versatility and effectiveness in diverse sectors.

# Essence of the Critical Path Method

The essence of the Critical Path Method lies in identifying critically interconnected tasks, forming a unified chain for project planning visualization. In practice, establishing multiple combinations of related tasks is impossible without utilizing IT solutions. To enhance the visual accessibility of the resulting plan, a network chart known as a Gantt diagram is employed.

During the calculation of the critical path, it is required to form a project model based on descriptions in several areas:

• List of Tasks: A comprehensive list of tasks or actions, where the outcome of one task serves as the starting point for the next.
• Time Allocation: The time required to accomplish each task or action in the chain.
• Task Dependencies: The mutual dependencies of tasks, indicating the transition from one action to the next.
• Intermediate Milestones: Specific results or milestones achieved at various stages.

Using this data, an optimal path is established in the task chain, minimizing total time consumption while ensuring all critical tasks are completed as planned.

Many scientific sources suggest that the critical path is the longest sequence of executable operations within a project. However, such a definition can be misleading. The length of the path refers to connecting graph vertices in a way that ensures minimum total path time, allowing for variability in achieving the set objectives and accommodating multiple versions of the project plan.

To better understand the essence of the critical path, it is advisable to consider a specific example.

Suppose there is a network of numerous points, each representing a specific task. Connecting two points corresponds to the time required for implementation. To optimize the overall project implementation time, the goal is to construct a path that traverses all points with the minimal total path length.

If the Traveling Salesman Problem involves finding the shortest path between two points while ignoring unnecessary ones, the Critical Path Method requires traversing all points systematically—hence the term “the longest path.”

# Which Path Is Critical

Non-critical paths are those segments of the chain whose movement does not influence project completion times. Consequently, their implementation can occur at any convenient time and speed without affecting the final project deadlines. Such tasks within a project are considered reserves and offer flexibility in project planning.

Conversely, changes in project completion dates due to alterations in any of the path segments are deemed critical. Typically, critical tasks are characterized by mutual dependencies, meaning they influence the start or completion times of others. In some cases, tasks are associated with immutable parameters that cannot be altered, such as specific regulatory deadlines or fixed operational schedules.

The set of critical tasks forming a unified chain constitutes the critical path. Projects can have multiple such paths, and their implementation may be sequential or parallel across various processes. Some tasks may be executed independently, requiring completion at a designated time with minimal dependency on other tasks.

The primary advantage of the sequential path method is the ability to build a single chain of consecutive actions from existing tasks or use a combination of “waterfalls,” each with a defined start and end point. This structured approach is particularly beneficial for startups seeking to streamline their project workflows and for venture capital firms aiming to ensure timely project deliveries.

For example, consider the need to repair a car. This involves several tasks: selecting a reputable workshop, diagnosing the issue, acquiring necessary parts, and performing the repair. Each of these tasks is critical because achieving the objective is impossible without completing each step. Repairs cannot be carried out without purchasing parts, and acquiring parts is only possible after diagnosing the issue. This illustrates how the Critical Path Method ensures that all essential tasks are completed in the correct sequence to achieve the desired outcome.

# Application of the Critical Path Method in Project Planning

Firstly, applying the method involves breaking down the entire project into individual components. This allows for simplifying and improving the accuracy of predicting the timelines for each stage, identifying the necessary resources, determining the scope and type of required actions, communication order, and more. For startups and private equity firms, this level of detailed planning is crucial for securing investment opportunities and ensuring project success.

Secondly, it’s essential to establish critical tasks and identify their mutual connections. As the number of identified nuances increases, planning accuracy improves, enabling better decision-making and resource allocation. Tools like Co-Founder Ai can assist in managing these complex dependencies, providing startups and venture capital companies with the insights needed to optimize their project timelines.

Thirdly, the result of this work is an optimized plan reflecting potential implementation timelines and key points of highest importance. This simplifies project management processes and provides a clear roadmap for stakeholders, investors, and team members alike.

By integrating the Critical Path Method into project planning, startups can enhance their operational efficiency, reduce time-to-market, and increase their attractiveness to investors such as angel investors and venture capital firms. Moreover, for private equity companies and venture capital business entities, understanding and applying CPM ensures that their investments are managed effectively, maximizing return on investment and minimizing risks associated with project delays.
