Project Manager vs Product Manager: The Differences

Knowledge background

First of all, from the point of knowledge area, technical background is required for project management. A typical project manager is a research and development engineer with rich project experience. His/her responsibility is to transfer the project’s goal into a measurable and achievable project plan, which means his/her job focuses on an aspect of execution. On the other hand, the knowledge area of a product manager is usually wider, but not necessarily require a technical background.

Duty cycle

Second of all, from the point of duty cycle, a project manager has to carry one’s duty through to the end. The project manager can switch to another project once he/she finishes a project while the product manager can not. The product manager has to grow up with his/her product, and the growth of a product usually comes along with countless projects, each of which is an iteration of the product.

Points of focus

The product manager focuses on “what product should do?”.

Responsible for product’s plan, including market analysis, components analysis, user analysis et al. Developing product scheme and plan, and coordinating product design, industrial design, and product development et al.

In a word, the product manager is in charge of the requirement and concept of the product.

The project manager focuses on “how to develop the product?”

After the product manager defines the requirement and concept of the product, it’s the project manager’s job to establish a team and realize the product using the methodology of project management. The main factors under consideration would be schedule, cost, quality, and production et al.

In a word, the project manager is in charge of the achievement of the product which has been defined by the product manager.

Substantial differences

Fourth, if a product could be compared to a child, then the product manager would be the child’s mother, and the project manager would be a teacher of a certain stage of the child’s growing up. There are different types of teachers. For instance, a primary school teacher can teach a class of students from grade one to grade six. After the child’s graduation from primary school, this teacher would switch to another class of students. From this metaphor, the relationship between the product manager and project manager can be clearly comprehended.

Please consider this: a child’s teacher can be changed, but how about the child’s mother?

Supplementing each other

Lastly, on the topic of project manager vs product manager, the most important thing is, the project managers and product managers supplement each other.

If a product manager could not provide a good concept, or a good strategy, or a good plan for a product, then the product’s development direction and the route would be wrong. In this scenario, even if the project manager had finished the project and achieve the product so well, there would be no success.

On the contrary, if the project manager could not nicely control the performance of the project, or deliver the product under constraints of schedule, quality, cost, and quantity, then the product plan would not be achieved, no matter how good the plan is.

In summary, the product manager determines the upper limit of a product, and the project manager determines the lower limit of achievement. Certainly, if there were not enough resources, all would be a tale of a tub.
