SAFe Scrum Master

The SAFe Scrum Master is a servant leader who helps educate the agile team in Scrum, Built-in-Quality, Kanban, and SAFe. They also help remove impediments and encourage continuous flow and relentless improvement in the development process. The SSM also assists the teams in self-organization and self-management to help them coordinate and participate in Agile Release Trains (ARTs) events.

Some of the specific roles of the SAFe Scrum Master are:

1. They ensure that the scrum ceremonies work efficiently and that the agile team follows the scrum framework.

2. SAFe scrum masters are responsible for coaching the scrum team, Product Owner, and stakeholders to understand the scrum practices. They also guide on how to implement and adopt agile principles.

3. They are responsible for fostering collaboration among team members so that everyone is working towards the same goal.

4. They manage dependencies and resolve impediments that arise during the project. The SAFe scrum masters also work closely with other scrum masters and agile teams, to resolve issues that affect the project’s progress.

5. Before preparing for the PI planning, they work closely with Product Owner to identify the stories, maintenance, defects, and other tasks the agile team needs to achieve during the upcoming PI.

6. They maintain the team’s workflow by eliminating impediments, delays, and waste.

Release Train Engineer

The Release Train Engineer is a servant leader facilitating ART practices and PI planning. They often participate in the Lean-Agile transformation, coaching teams, and leaders to obtain new mindsets and processes.

Some of the specific roles of the Release Train Engineers are:

1. The Release Train Engineer is accountable for managing the Program Backlog, and making sure it is prioritized and groomed for upcoming Program Increments (PI).

2. They work closely with the product owners and stakeholders to check whether the Backlog aligns with the PI objectives.

3. The RTEs are also responsible for facilitating continuous improvement across the ART. They encourage teams to reflect on their processes and identify areas for improvement to increase productivity.

4. They monitor and manage the ARTs performance to meet the business objectives and KPIs. And they also help agile teams identify and address the performance issues that arise during the process.

5. The Release Train Engineer coaches scrum masters in ART, team events, and practices such as PI planning, iteration planning, backlog refinement, and more.

6. They also coach other leaders like business owners, system architects, and product management teams in achieving a new agile mindset.

How does the job role of Release Train Engineer differ from SAFe Scrum Master?

Here is a detailed discussion about how these two roles differ from each other:

1. The SAFe scrum master’s scope is restricted to a single agile team, whereas the Release Train Engineer’s scope is the coordination and leadership of the entire ARTs.

2. The SSM focuses on coaching and mentoring the agile teams, while RTEs are accountable for leading the Agile Release Train towards the program objectives.

3. While the SAFe scrum master manages the team backlog, on the other hand, the Release Train Engineer manages the program backlog aligned with the PI vision.

4. The RTEs play a major role in leading the ART, managing risks, addressing impediments, and ensuring the program delivery on time within budget compared to the SAFe scrum master.

Overall, both the servant leaders are skilled facilitators with a deep understanding of the agile manifesto and practices.
