Certified Six Sigma Black Belt Exam Certified Six Sigma Black Belt Lean Enterprise Concepts 1

Question 1

In a Lean enterprise, 'takt time' is best defined as:

Accepted Answer

The rate at which products must be completed to meet customer demand

Answer

Takt time synchronizes production pace with customer demand rate. It is calculated as available production time divided by customer demand, ensuring the enterprise produces at exactly the rate customers require — no faster, no slower.

Question 2

Which Lean technique is specifically designed to reduce changeover or setup time between production runs to under ten minutes?

Accepted Answer

SMED

Answer

SMED (Single-Minute Exchange of Die) is the Lean methodology focused on reducing equipment changeover times to single-digit minutes. It does this by converting internal setup steps (done while the machine is stopped) to external steps (done while the machine runs).

Question 3

A Lean value stream map (VSM) is primarily used to:

Accepted Answer

Identify and visualize all steps — value-added and non-value-added — in a process flow

Answer

A Value Stream Map depicts every step, delay, and information flow from raw material to customer delivery. By making the entire flow visible, teams can identify waste, bottlenecks, and opportunities for improvement that are otherwise hidden.

Question 4

In Lean enterprise, 'heijunka' refers to:

Accepted Answer

Leveling production volume and mix over a given time period

Answer

Heijunka (production leveling) smooths out production by distributing volume and product variety evenly over time. This prevents the peaks and valleys of demand from propagating instability upstream through the value stream.

Question 5

The 5S methodology in Lean enterprise refers to five practices, the first of which — 'Sort' — means:

Accepted Answer

Removing all items from the workplace that are not needed for current operations

Answer

The first S, Sort (Seiri), means eliminating unnecessary items from the work area. By removing unneeded tools, materials, and equipment, the team reduces clutter and makes it easier to see what belongs — a prerequisite for the remaining 5S steps.
