Agile Release Train
What is an Agile Release Train (ART)?
An Agile Release Train (ART) is a long-lived team of Agile teams, typically consisting of 50-125 individuals, that develops and delivers solutions incrementally using agile methods and a common cadence.
Synonyms: SAFe Agile Release Train, ART in Agile, Scaled Agile Release Train, Program-level Agile team
How Agile Release Trains Work
Agile Release Trains (ARTs) are a key component of the Scaled Agile Framework (SAFe). They align teams to a common mission, working in synchronized iterations and increments to deliver value continuously. ARTs typically operate on a Program Increment (PI) cadence, usually 8-12 weeks long, with shorter sprints within each PI.
Benefits of Agile Release Trains
- Improved Alignment: ARTs ensure all teams are working towards common objectives.
- Faster Time-to-Market: By coordinating multiple teams, ARTs can deliver complex solutions more quickly.
- Enhanced Quality: Regular system demos and built-in quality practices lead to better outcomes.
- Increased Productivity: ARTs reduce dependencies and streamline communication between teams.
Implementing Agile Release Trains
Implementing an ART requires careful planning and organizational change:
- Identify the value streams in your organization.
- Form cross-functional teams aligned with these value streams.
- Establish a common cadence and synchronize work.
- Implement SAFe roles like Release Train Engineer (RTE) and Product Management.
- Plan and execute Program Increments (PIs) with all teams.
Frequently Asked Questions
- What's the ideal size for an Agile Release Train?: While ARTs typically include 50-125 people, the exact size can vary based on the organization's needs and the complexity of the solution being developed.
- How often does an ART deliver?: ARTs usually deliver value at the end of each Program Increment (PI), which is typically 8-12 weeks long. However, teams within the ART may deliver more frequently, often at the end of each 2-week sprint.
- Can ARTs work for non-software products?: Yes, while ARTs are commonly used in software development, they can be adapted for other complex product development scenarios, including hardware and systems that combine hardware and software.
