Lean

In this blog post, the concepts of Little’s Law, lead time, cycle time, and throughput are explored through an analogy involving whisky bottles. Two problem statements concerning whisky consumption and purchases are presented, leading to the derivation of key parameters such as work in progress (WIP), throughput, cycle time, and lead time. The post offers two solutions that highlight the equivalence of the formulas employed, simplifying intricate concepts in queuing theory for readers. Additionally, the Cumulative Flow Diagram is introduced as an efficient tool for visualizing and managing work processes.
