Developer Rotations: Promote Long-Term Project Success

Developer rotations — cycling one or two team members off a long-term project every six to twelve months — offer multiple benefits: they stress-test documentation, provide architectural audits through fresh eyes, surface hidden assumptions, combat complacency, build generalist expertise across the team, and reduce risk from unexpected personnel changes. Keeping enough experienced members ensures continuity while new arrivals provide honest feedback on how understandable and maintainable the codebase really is.
