Lean Metrics: Measure Predictability with Facts over Estimates

Businesses can improve work predictability with Lean metrics, such as process control charts, which graphically represent cycle time and completion consistency. With three standard deviations, teams can predict and narrow the range of delivery dates, which can help make more accurate estimates and adjust timelines. These metrics can also be used for continuous improvement, such as reducing the range of outcomes, limiting work in progress, and analyzing out-of-control data points. Using factual and historical data can lead to better work prioritization and targeted communication with stakeholders, resulting in more predictable outcomes.
