180 views

Overproduction and Waiting are two of the seven categories of waste. Overproduction involves producing more than is immediately needed, leading to excess inventory and wasted resources. Waiting refers to idle time when resources are not being efficiently utilized, which can halt productivity and increase costs.

FAQs & Answers

  1. What are the seven categories of waste in lean manufacturing? The seven categories of waste include Overproduction, Waiting, Transport, Extra Processing, Inventory, Motion, and Defects.
  2. Why is overproduction considered a waste? Overproduction leads to excess inventory, tying up resources and increasing storage costs without immediate demand.
  3. How does waiting affect productivity? Waiting causes idle time for workers or machines, slowing down processes and increasing lead times.
