When size doesn't matter: A case study on adopting agile in large enterprises by Damir Bajrektarovic and Haris Krkalić


Published on

Although agile can yield significant advantages, the journey is not always easy. Agile methods have become an appealing alternative for companies striving to improve their performance, but the methods were originally designed for small and individual teams. This creates unique challenges when introducing agile at scale, when development teams must synchronize their activities and there might be a need to interface with other organizational units. Agile principles indeed can be applied to large, even very large, groups of people, allowing them to be more connected to their work and its impact, despite being part of a huge system. As Agile scales up, it also scales 'out' across an organization's value chain -- to departments outside of product development -- to deliver a valuable product or service to the market. This is the story of how we managed to challenge teams to synchronize their activities, to improve performance. The story of non-agile becoming agile. Story of how we leveraged our customers' loyalty, and how we tailored agile strategies to our organisation's needs.
