Preguntas Frecuentes
What is Little's Law?
Little's Law states that the average number of items in a system equals the average arrival rate multiplied by the average time spent in the system.
Why should WIP be minimized?
High WIP increases lead time, ties up capital, hides quality problems, and reduces process flexibility.
How can I reduce WIP?
Implement pull systems, reduce batch sizes, improve flow, and reduce changeover times to lower WIP levels.
