Tiger teams: How we tackle urgent, cross-functional challenges at Grafana Labs (8 minute read)
Grafana Labs successfully used "tiger teams" – small, focused groups of specialists – to address high-priority, cross-functional problems, improving release cycles and tackling urgent issues. Originating from NASA's Apollo 13 mission, these teams at Grafana Labs consist of three to five specialized engineers who work temporarily, typically for one to two quarters, until a specific goal is achieved, such as simplifying the release process or securing a major partnership. The success of the Release Tiger Team led to the creation of a full-time dedicated team to iterate on release issues, though tiger teams can also be dissolved once their objectives have been met.
