Scrum Master vs Project Manager: Which is the Ideal Approach in 2021?

No matter which industry you are a part of, it’s unlikely you haven’t heard of these two terms – Scrum Master and Project Manager. A superficial glance might lead you to believe that there isn’t a difference between the two. But, a closer look will tell you that’s not so. 

While a Scrum Master upholds Agile Methodologies, a Project Manager operates on traditional disciplined project management principles. There’s plenty more to the two roles though which we will discuss in this article. We will also throw light on the various responsibilities of a Scrum Master and Project Manager. Finally, we will look at the differences and similarities between the two profiles. 

Scrum Master: Definition

Let’s start by understanding the Scrum methodology: there is a product owner, a scrum and a scrum master. 

The Product Owner assigns a task, and a scrum (a development team) breaks the job into smaller fragments known as sprints.

A sprint is a set of effective development procedures that involve reiterative testing and collaboration to reduce the lifestyle of a project. These are known as agile Scrum methodologies that lead to product completion in a short period of time. 

A Scrum Master is a job role assigned to the team member who ensures these agile values and principles are being followed and that the team is working as per the practices and objectives they previously agreed on. The framework works towards agile adaptive product development through a facilitator (Scrum Master). In this manner, a Scrum Master is essentially the leader of his scrum team.

Making Mistakes

For both the Project Manager and Scrum Master, there is room for error.  However, they also right the wrong and are expected to learn from their mistakes. The entire framework works on transparent communication, feedback, alleviating incoming risks, and creating a culture for better bonding opportunities in a team.


A Project Manager is accountable to the client he is working with or his stakeholders. A Scrum Master has to report to the same figures of authority as well as the Product Owner. Neither can assume the position of final authority.


Both the Project Manager and the Scrum Master are bound to fail if they override the foundational principles. Not adhering to them becomes the cause of inconsistencies and instability within an organisation. If they ignore professionalism and are not skilled as per the standards of professionalism, they will fail. There is also the likelihood of failing when a team member’s opinions are not given due respect and attention.


Both Project Manager and Scrum Master have widely used approaches towards management today. There are organisations that also operate on a hybrid model based on the two. However, it’s up to you and your business needs when it comes to selecting one of the two approaches in your organisation. In any case, you would need a skilled professional to assume the role of the Project Manager or Scrum Master – whichever you decide to go with.
