Little's Law establishes a relationship between three flow metrics: Work in Progress (WIP), Cycle
Time, and Throughput. It provides insights into how changes in one metric affect the others in a
stable system.
Little's Law is used to understand and manage flow within a system but is not a forecasting tool for
output or future performance. It assumes a stable and predictable system where the input and
output rates are consistent.
Why Not True?
Forecasting requires variability, historical data, and often different statistical models. While Little's
Law supports system predictability and capacity planning, it does not directly project future Scrum
Team outputs or delivery dates.
Thus, Little's Law helps teams analyze and optimize flow but is not used for forecasting.
