Continuous improvement — kaizen — means small, ongoing changes driven by the people doing the work, so the team gets better every Sprint rather than only during occasional reorganizations. It is the engine behind Agile's "inspect and adapt," and it lives or dies on psychological safety and follow-through.
How to embed it
- Make retros produce 1-2 owned, tracked actions (and verify them)
- Run small experiments: hypothesis → try one Sprint → inspect
- Surface problems early; reward raising issues, not hiding them
- Use metrics (cycle time, flow) to spot what to improve
- Spread learning across teams (communities of practice)
Concrete example
A team treats each retro action as an experiment: "we think smaller PRs will cut review time — let's cap PR size for one Sprint and measure." They keep what works and drop what doesn't, compounding gains over months.
