Guide to LeSS (Large-Scale Scrum)

What is LeSS (Large-Scale Scrum)?
LeSS is an acronym for Large-Scale Scrum. It is a framework for scaling agile development to multiple teams working on the same product. It promotes iterative development, customer-centric focus, and flexibility to adapt and respond to changes.

Why is it important?
LeSS is essential because it streamlines the process of scaling scrum to larger teams while maintaining the agility and efficiency of a smaller scrum implementation. It fosters alignment, transparency, and streamlined communication across large teams, which is critical for the successful implementation of complex projects.

How does it work?
LeSS works by, chiefly, keeping the scrum's original design while minimizing the unnecessary complexity and hierarchy. All teams are working on the same product and share the same product backlog. There's one Product Owner, and roles such as managers have a significantly minimized contribution.
Everything is coordinated during the 'Overall Retrospective' at the end of the sprint feedback loop. There are three main principles in LeSS: thinking on a large scale, lean thinking, and systems thinking.

Answering Questions on LeSS in Exams:
When answering questions about LeSS, focus on its key principles and values. Understand the structure and roles within LeSS and its emphasis on optimizing the whole system rather than individual components. It's vital to grasp that LeSS prioritizes delivering customer value and maintaining alignment across teams.

Exam Tips:
The first tip is to fully understand the LeSS principles and rules before tackling questions. Remember that LeSS is about simplifying, not adding complexity. Review the LeSS events and their purpose, and focus on the role of the Product Owner and the overall sync.
Do not neglect the concept of system and lean thinking in LeSS.

As a final tip, practice answering past exam questions to get a feel for the type of questions you could encounter.
