CLL Lean Principles & Value Stream Mapping 3

Question 1

Which type of waste in the Lean 8 wastes category describes producing more than what the customer currently needs?

Accepted Answer

Overproduction

Answer

Overproduction — making more, earlier, or faster than required — is often called the worst waste because it generates and hides other wastes.

Question 2

When mapping a future state VSM, what is the first question a lean leader should answer according to Lean fundamentals?

Accepted Answer

What is takt time?

Answer

Establishing takt time is the first step in designing a future state because it synchronizes production pace with customer demand.

Question 3

A VSM timeline shows 'C/T = 45s' below a process box. What does C/T stand for?

Accepted Answer

Cycle Time

Answer

C/T in VSM data boxes denotes Cycle Time — the actual time to complete one unit at that process step.

Question 4

What distinguishes a 'value-added' activity from a 'necessary non-value-added' activity in Lean?

Accepted Answer

Value-added activities directly transform the product in a way the customer pays for; necessary NVA activities are required by the business but add no customer value

Answer

Value-added steps physically change the product in ways customers value and pay for; necessary NVA steps (like legal compliance) are required but create no direct value.

Question 5

In a Lean value stream, a 'supermarket' represents:

Accepted Answer

A controlled inventory buffer where downstream processes pull what they need

Answer

A supermarket is a precisely sized, managed inventory point from which a downstream process pulls only what it needs, when it needs it.
