4 Reasons Why Project Planning Is Essential

The project planning process is holistic and encompassing. This post describes the process using a simple and easy to remember mnemonic.

The project planning process is holistic and encompassing. It is at the heart of project benefit viability.

What’s more, project planning is a great way to bring the project team together.

Be Prepared: Be Ready, Willing and Able

Here are 4 reasons why project planning is essential. The effort put into project planning can make or break a project, so we wish to share a useful mnemonic for remembering the project planning process:

prêt Adj. Disposé, en état de. Synonym bon Anglais ready

The  project planning process should follow a particular sequence. It is …


The identification of the project’s products — the product breakdown structure.


Listing the resources needed to deliver each product.


Calculating the effort and costs associated with each product.


Setting time-scales for the project.

PRȆT: Products, Resources, Effort, and Time-scale.

Follow these steps, and you’ll be ready to move on!

Stick to the Project Planning Process

When the project sponsor assumes time is of greater importance than cost, they may exert pressure on the project team to omit the planning process.

Don’t be bullied!

The project plan must begin with a reasonable understanding of what the project intends to deliver. That is, its products. Only then can we consider the resources needed and the likely effort and costs.

If you fail to follow these 4 basic steps, it should be of no surprise when the project takes longer than expected to deliver, suffers from a cost overrun or simply doesn’t deliver what was required.

Of course, even when you follow these steps, the plan may fail to meet one or more expectation of cost, time, and scope. Perhaps cost and scope is fine, but the timescale is too long.

Consequently, the plan will need to be reviewed and refined. This could take several iterations, which is why we should always aim to plan in outline for the whole project and in detail for the next stage. As the project makes progress, more information is available, and our estimates prove more accurate.

Do teams work together to design projects in your organization? Or, is the project manager solely responsible for project planning? You are welcome to tell us about your experiences in the comments.
