Of course, these roles can also vary greatly depending on the types of products or projects being executed in the organization. For example, manufacturing product managers are responsible for tangible products, while software development product managers will have different teams and agile workflows to assist in the software product launch.

Additionally, while both roles are technically geared for the delivery of products and projects, there are different processes and best practices required. For example, many project managers are accustomed to working within the PMI guidelines for best project management practices. Whereas product managers might rely on agile product development, lean manufacturing processes or lean software development methodologies.

Today we’re talking about a product manager versus a project manager. They sound similar but the roles are different. Let’s take a look at how.
First of all, the product manager is responsible for leading the team to deliver the end product. They’re responsible for the strategy, the product roadmap, as well as the feature definition of the product.

There is also a separate product life cycle for delivering that product that the product manager is responsible for managing. They also are responsible for leading the product team. The product manager also can work directly with the project manager as well as the customer and the product team.

The project manager is responsible for leading the team to deliver a successful project. They’re responsible for the strategy and the process flow of the project. They’re responsible for the project plan as well as the requirements for the project.

And, there is a separate project life cycle the project manager is responsible for managing. They also have an entire project team that they’re responsible for leading. The project manager can work directly with the product manager. They can also work directly with the customer and the project team as well as the product team.

Both roles can be perceived as CEO-like. It depends upon the complexity and the span of control and if it includes being responsible for the profit and loss statement or forecasting for the project. Then, there are a couple of areas of conflict that can arise. First of all, who owns the product road map? Of course, you would suspect that the product manager wants to own that, but sometimes the project manager does as well.

So, you have to determine who really owns and is responsible for the product road map. And then, who gets to talk to the product team or the customer? Both can, but as you can suspect, then it can get confusing if too many people are going to each and asking for input or provide status.
