Quiz

A design platform in the mould of Canva moves 90 engineers off long-lived feature branches onto trunk-based development with a merge queue. Six weeks later the mean branch still lives four days and the trunk is no healthier. Review this change. What did they actually need to change?

A platform with many teams and frequent releases must choose a branching model. What decides it?

A product ships versioned software that customers install and run themselves. Three major versions are under support and security fixes must reach all of them. Which branching model fits?

Sixty engineers work on branches that live five days on average before merging. Estimate what that lifetime costs per year, and say which assumption dominates the error.
