Question 1

Which lean principle states that products should flow through processes without interruption, backflow, or waiting?

Accepted Answer

Continuous flow (one-piece flow) eliminates batching and queues so each item moves directly from one process step to the next.

Question 2

When applying SMED (Single-Minute Exchange of Die) in a warehouse context, the primary goal is to:

Accepted Answer

Convert internal setup tasks to external tasks to reduce downtime

SMED focuses on converting setup steps done while equipment is stopped (internal) to steps done while it runs (external), cutting changeover time below 10 minutes.

Question 3

In a lean value stream, a 'push' system is characterized by:

Accepted Answer

Manufacturing or picking goods based on forecasts or schedules regardless of downstream need

Answer

A push system produces or moves inventory based on planned schedules, often creating overproduction and excess inventory when forecasts are inaccurate.

Question 4

Which type of waste involves storing more inventory than is immediately needed to fulfill customer demand?

Accepted Answer

Inventory

Answer

Inventory waste occurs when excess raw materials, work-in-process, or finished goods are held beyond what current demand requires, tying up capital and space.

Question 5

What does 'takt time' represent in lean warehouse operations?

Accepted Answer

The available production time divided by customer demand rate

Takt time is the pace at which work must be completed to match customer demand, calculated as available work time divided by units required.
