In the Scaled Agile Framework (SAFe), Agile Release Trains (ARTs), each comprising a coalition of agile teams united under a common mission and synchronized through a shared ART Backlog, play a central role in delivering business products and solutions. Typically, an ART accommodates 50 to 125 individuals. Orchestrating this setup is the Release Train Engineer (RTE), a servant leader who streamlines the solution delivery process, nurtures self-organizing teams, and proactively eliminates potential obstacles to team progress.

Further, the RTE ensures teams are adequately prepared for effective planning, striking a balance between adaptability and predictability, and coaches various roles within the release train, including the Scrum Master/Team Coach, Product Owner, Product Manager, Business Owner, System Teams, and System Architect. This guidance hinges on lean agile principles with an unyielding focus on continuous improvement and value delivery.

The RTE is tasked with adapting SAFe to specific organizational needs while maintaining the integrity of its core principles. This involves recommending, standardizing, and documenting best practices consistent with SAFe’s philosophy. To facilitate a comprehensive understanding of the RTE’s role, SAFe categorizes the RTE’s activities into five domains, providing a structured framework for a detailed exploration of their responsibilities.

Responsibilities of SAFe Release Train Engineer (RTE)

Facilitating Planning Interval (PI) Planning

The PI Planning meeting is a recurring event involving all Agile Release Train (ART) members and stakeholders. This critical meeting aligns the entire ART with a shared vision and facilitates collaborative planning for the forthcoming Planning Interval (PI), a fixed timebox of 8 to 10 weeks for developing a solution. Release Train Engineers (RTEs) play a pivotal role in ensuring the success of this event by aiding in preparation and facilitations.

Supporting PI Execution

As leaders of Agile Release Trains, Release Train Engineers (RTEs) carry a profound responsibility for the successful execution of Planning Interval (PI), working diligently towards achieving PI Objectives. During the PI, their roles encompass the following tasks:

  • Enhancing Visibility and Transparency – Transparency is a core value of the Scaled Agile Framework (SAFe). RTEs work diligently to foster an environment of openness in all work areas. They aid in developing the ART Kanban System, designing suitable stages and policies to ensure the visibility of progress and issues related to features in real time. This could involve configuring the tools required for managing the Kanban system effectively. RTEs also encourage teams to maintain transparency about their work, their definition of ‘done’, and to facilitate frequent system demos. This aids in fostering alignment and improving visibility of progress.
  • Facilitating Synchronization Events – The agile principle values individuals and interactions, advocating for transparency and collaboration. In SAFe, this manifests in ART level synchronization meetings like the ART Sync, System Demo, and PI System Demo. RTEs ensure these events foster collaboration and adaptation to achieve PI objectives, and they facilitate these meetings to maximize effectiveness.
  • Managing Risks and Dependencies – Risks identified in PI Planning (ROAMed) must be tracked throughout the PI to mitigate their impact on PI objectives. Dependencies must also be tracked to prevent them from causing delays. RTEs facilitate this tracking process, using the ROAM technique and the ART Planning Board.
  • Supporting ART Backlog Refinement – While Product Management typically leads ART backlog refinement, RTEs ensure that the ART backlog is refined to the appropriate level to support prioritization, incremental value delivery, and predictability. They work to uphold the SAFe Value of Alignment during this process.
  • Promoting DevOps and Continuous Delivery – RTEs strive to integrate quality into the process and promote automation where possible to enhance the flow of value. They advocate for DevOps and the Continuous Delivery Pipeline, including Built-in Quality and the Lean User Experience (UX) innovation cycle.
  • Assisting Business Owners – RTEs aid Business Owners in evaluating economic trade-offs, thereby improving economic decision-making. They provide support with relevant metrics, operating within the governance framework established by Business Owners and Lean Portfolio Management.
  • Coordinating with Other ARTs – Especially when part of a Large Solution, RTEs establish and communicate the annual calendars for Iterations and PIs. They also schedule any pre-planning activities in coordination with other ARTs.

Coaching the ART

Coaching is intrinsic to the agile leadership style. As servant leaders, Release Train Engineers (RTEs) strive to cultivate more leaders by providing training, mentoring, and coaching.

  • Mentoring Scrum Masters/Team Coaches in ART and Team Events and Practices – RTEs guide Scrum Masters (SMs) and Team Coaches (TCs) in comprehending their roles and responsibilities. Given that SMs and TCs also serve as leaders at the team level, their leadership is crucial to the success of the ART. Thus, RTEs ensure that SMs and TCs are appropriately trained, mentored, and coached to excel in their roles. To learn more about SM/TCs role, refer to our blog post, “Roles and Responsibilities of a SAFe Scrum Master“.
  • Coaching ART Roles – In the context of other ART roles, the RTE primarily adopts a coaching stance. They coach Business Owners, System Architects, and Product Management, fostering collaboration among teams and System Architects. Additionally, RTEs provide training and mentorship on Lean-Agile practices and mindsets for Agile Teams and the ART.
