Which Roles Are Needed to Successfully Deliver a Software Project?

software project

Before starting a project, the essential thing is to determine which roles are needed to deliver a software project successfully. Of course, the key people in software development are programmers. But ask yourself, is that enough? Do you need help from other experts in achieving your project goals?

The truth is that the success of a software project depends on the right people involved in it and positioned in the right places. In addition to software developers, you may need a team of people from different areas of expertise, such as product owners, scrum masters, QA engineers, UX designers, and others.

If these roles are not assigned, poorly selected, or the responsibilities are not precisely defined, you can end up failing to achieve your objectives. Instead, you can think one step ahead and take advantage of the Scrum methodology.


Scrum as a Methodology to Deliver Software Projects


When we don’t implement a project successfully, we blame everyone for the failure. For instance, business owners can blame developers, managers, or other team members.

The scrum methodology wants you to fail. Failure is a good thing as long as you are learning from it. Blaming others is unacceptable since it indicates something is wrong with your project delivery process.

Scrum is a framework that brakes complex software projects into small pieces and allows team members to deliver value in a collaborative environment. Instead of blaming each other, the framework promotes a team collaboration culture.


Size of a Scrum Team and Required Roles


How do we determine the proper size of a scrum team? The number of team members varies, depending on your project size. However, consider that every scrum team needs a product owner, a scrum master, and a team of developers.

Theoretically, the product owner and the scrum master are different people’s roles. Our approach differs as we unite these roles in what we call the “Delivery Manager.”

However, let’s stick with the proper theory: The product owner (PO) ensures the team works on the right priorities and achieves the highest possible quality. The scrum master coaches the whole team and ensures that procedures are followed so that the collaboration is efficient. Both roles are 100% committed to the team.

Generally, the ideal size of a scrum team is around seven members. Since this depends on the project size, it is best to adhere to the following guidelines:

  • Smaller projects – PO, scrum master, and two developers
  • Medium and large projects – PO, scrum master, five or more developers

As you can see, only the number of developers varies. The number of other roles stays the same. Keeping your scrum team simple can help you move forward toward your goals.

Too many roles can only distract your team members from their responsibilities and bring confusion within the team. That’s why we unite the part of the PO and the scrum master and call it the “Delivery Manager.”


Scrum Team Roles


Before defining the scrum team roles, you should understand how the team members will work together. To deliver great software products, each team member should know their responsibilities.

Equally important, scrum represents a better way of developing software by doing your tasks and helping others do theirs. In those circumstances, team members are expected to go above and beyond their assigned duties and assist others in advancing the project’s objectives.

It can be challenging to find individuals who align with this work philosophy, which is why some organizations outsource software development to companies that fully embrace Scrum principles.

Product Owner


The product owner (PO) ensures that the highest possible value of a product is being delivered to the users. Technically, this role requires managing the product backlog and creating user stories. But the role of the PO is more than that.

To understand this role better, here are the main product owner tasks:

  • Setting project goals
  • Making strategic decisions
  • Filling the backlog of work and prioritizing tasks
  • Collaborating closely with developers to establish the progress made
  • Conducting sprint planning to establish what can be achieved during the upcoming period
  • Communicating with users and other stakeholders to collect feedback


Scrum Master


The scrum master is responsible for solving day-to-day issues and helping the scrum team progress without distractions. To succeed in this, a scrum master must have advanced Scrum knowledge and communication skills to spread the knowledge within the team.

Here are the primary responsibilities of the scrum master role:

  • Ensuring adherence to the Scrum methodology and promoting efficient collaboration among team members.
  • Moderating Scrum meetings and coaching other participants
  • Working closely with the PO to keep the product backlog effective
  • Staying regularly in touch with the team via video calls or chat
  • Supporting open dialog and removing any roadblocks


Software Developer


A scrum software development team is a group of people skilled enough to build software products together. However, this team only sometimes contains just software developers. 

Other roles benefit software projects like designers, architects, or QA engineers.

UX/UI design plays a crucial role in software development projects as it allows for understanding the product from the end-users perspective. This is why having a designer on the Scrum team is vital when the product includes a frontend component.

Testing has to go in parallel with the development, so having a QA engineer as a part of the scrum team is a good idea. The QA specialist is accountable for conducting tests to ensure the product runs smoothly before entering the market.

Note that most projects will require the software architect and DevOps engineer roles. A software architect helps the team define the software’s primary structures, including interfaces, APIs, and more. The position requires a high level of technical knowledge since making these choices is only possible by thinking many steps ahead in the software development process.

A DevOps engineer manages the infrastructure of the software, including the different environments and deployment of new releases, and ensures principles like CI/CD are met. This also includes monitoring the system and suggesting plans for enhancements.

Some projects require adding a data scientist or machine learning engineer to your team. They drive decision-making in your team by collecting and analyzing large amounts of data and developing the algorithms to solve the most challenging problems.

Apart from the tech skills, all these people need to understand the Scrum methodology deeply. Whether we are talking about programmers, software architects, or UX designers, a scrum developer role consists of the following activities:

  • Converting the sprint backlog items into software features
  • Accomplishing goals defined for each sprint
  • Setting up goals for the next sprint through backlog grooming
  • Understanding and following user stories
  • Attending daily scrum meetings and reporting any problems
  • Working together with the rest of the team in daily closing tasks

  • Do not have enough in-house tech talent
  • Have problems managing significant and complex projects
  • Cannot meet your deadlines
  • Want to adopt the agile way of doing business



Starting a software project without pre-defined key roles could lead to failure. One of the most common misconceptions is that projects fail because of poor software developer skills. But the truth is, they fail because of poor management processes.

We want to appreciate the power of highly skilled people. However, you can only expect good results with a system in which all these people are positioned in the right places and guided by experienced managers.

In this case, the Scrum framework is everything you need. It clearly defines three leading roles responsible for a project’s success. Every scrum team should have a product owner, scrum master, and several developers, depending on the project size.

The product owner reviews the team’s work and ensures the highest value is being delivered. The scrum master keeps the team working sustainably and removes all obstacles.

The ideal size of a scrum team is around seven people, including developers. The number of developers may vary because of different project needs. But one thing is for sure, to deliver a software project successfully, you need to have all three roles mentioned above.
