Lean tools knowledge check

Learning objectives

Explain the purpose of lean tools knowledge check in garment operations.
Describe when and how to apply lean tools knowledge check on the shop floor.
Identify common mistakes and how to avoid them.

Scenario

A mixed-style line has excess WIP, long travel, unstable output, defects and slow changeovers.

Required reasoning

Select and sequence VSM, waste walk, takt/balance, spaghetti, pull/Kanban, standardized work, poka-yoke, SMED, visual management and constraint actions.

Passing guidance

Answers must connect tool to observed problem, data, people, safety, quality, response and sustainment—not name tools in isolation.

Garment-factory example

Apply the reasoning above to a live garment order rather than a textbook problem.

Method

Read the scenario twice.
Draft an answer using the required reasoning list.
Compare against the passing guidance and revise weak areas.

Common mistakes

Naming tools without linking them to the observed problem.
Ignoring people, safety, or sustainment aspects.

Knowledge check

Pick one answer per question. Explanations appear after you submit.

1. Which statement best captures the core idea of Lean tools knowledge check?
- A mixed-style line has excess WIP, long travel, unstable output, defects and slow changeovers.
- It is a purely financial control unrelated to shop-floor work.
- It replaces the need for standardized work and training.
- It applies only to fully automated factories.
2. A common mistake when applying lean tools knowledge check is to:
- Naming tools without linking them to the observed problem.
- Involve operators and validate with data.
- Link the tool to the observed problem and follow-up plan.
- Update the standard after a confirmed improvement.
