CPM is the one most powerful tool in project management. This is for managers in planning, scheduling, and controlling the project activities so that project completion is done timely and efficiently. Whether it is a building project, product launching, or organising an event, the Critical Path Method can make the process much smoother and organised. In this article, we will discuss what CPM really is, why it is crucial, and how to utilise it step by step. This article will also elaborate on topics such as what is critical path in project management with examples, strategies for managing complex paths, and methods for determining the critical path in a project.

The Critical Path Method (CPM) involves managing the project by determining its activity sequences most important for timely completion. The critical path involves the longest series of dependent activities meaning that the delay in any of these will eventually affect the project's finish date. Project managers shall effectively manage resource allocation and priorities using this method through an effective focus on the critical path.
The Critical Path Method is important for several reasons:
CPM defines a clear timeline for all tasks appropriately scheduled for the resources.
It identifies the critical tasks and also those which have flexibility (slack or float).
The knowledge of critical paths will make sure that no use is made of resources for non-critical tasks.
It gives warnings to possible bottlenecks before a project manager could get into action about them.
By keeping track of the critical path, the manager can also keep an eye on the current progress status of the project and make appropriate corrective actions when necessary.
Consider an example of a simple project: organising a conference. Here are the steps to organise a conference:
Identify a venue.
Draw up an agenda.
Invite speakers.
Send invitations to the attendees.
Order catering.
Set up the venue.
Host the event.
all the activities shown above need to be broken down into individual tasks.
Each task will be given an estimated time for completion (e.g. finding a venue: 5 days, inviting speakers: 7 days)
Some of the tasks have predicates related to each other. For example, you cannot send the invitation until a planned agenda is set with confirmed speakers.
Critical Path Method is a process that requires a number of logical steps. Here follows the step-by-step guide:
Define chunking your project into small, manageable pieces; be sure all activities needed to complete the project are noted.
Estimation of how much time is necessary to finish each task. Please be as accurate as you can, using past experiences or consulting an expert.
Determine which of these tasks depend on the completion of the others. For example, in our conference example, invitations are sent once speakers are confirmed.
Using flowchart, Gantt chart, or project management software tools, build a database of all tasks and their interdependencies.
Carry out the longest path of dependent tasks via CPM calculations. You can do this by:
Summing up the time taken by the task present in each path.
Searching for the longest duration path. This will be your critical path.
Thus the critical path should, at intervals, be monitored and adjusted for schedule and resources. Whenever a task on the critical path is held up, action should be instituted immediately.
Managing a critical path can be perplexing at times, especially in bigger projects that include multiple tasks and their dependencies. In fact, prioritising the task and leveling resources have proven to be effective ways of managing this complex situation.
First, determine the critical path, so assign all resources it will require to ensure timely completion.
Adjust such resources to prevent overload or bottleneck in the team. In case two critical tasks overlap, allocate much-needed resources for both to ensure their completion on time.
Say, in a construction project, such as plumbing and electrical work that require a particular skilled labor supply at the same time and on the same work site, then you will get one of the jobs outsourced.
The critical path determination is a critical step in the CPM process. Here is how you can determine it effectively:
You need to identify all possible paths from the starting node to the end of the project. Each path will represent a sequence of dependent tasks.
Sum up the time estimates of the tasks within each path. Therefore, if a certain path consists of 5, 7, and 3 days activities, the total duration would be 15 days.
The longest path is the critical path. This path determines the minimum time for the project.
Commence CPM planning right as you begin your project.
To facilitate the identification and management of the critical path, diagrams, flow charts, or software become important.
Keep a close watch on the critical path and revise the schedule to show advances or delays.
Everyone in the team should clearly understand the critical path and his responsibilities.
Prepare contingency plans for tasks on the critical path to prevent delays.
The Critical Path Method (CPM) is an invaluable technique of managing projects effectively. By learning what is a critical path in project management with example, finding how to determine critical path, and applying strategies to manage its challenges, you can keep your projects on time and budget. Apart from this, CPM helps you identify those tasks that bear maximum importance and allows you to manage resources wisely and predict future risks.
The British Academy for Training and Development offers comprehensive courses on CPM for project management to help businesses achieve their goals.
