Andy Murray, while discussing the PRINCE2 V7 project management guidance, elucidates the concept of setting performance targets and managing them effectively. PRINCE2 recommends the use of tolerances, offering a margin for flexibility in project controls. This prevents managers from overreacting to minor deviations from a plan. The idea is to establish performance benchmarks, monitor progress against them regularly, and adjust accordingly. Using metaphors, Murray likens this to strategically landing on a specific lily pad or correctly aligning with a designated section of a runway during a plane's descent. This approach ensures the project aligns with its desired outcomes despite inevitable variations.
