,Q1 DEMONSTRATE MASTERY OF CORE CONCEPTS
A process has a takt time of 30 seconds and a cycle time of 45 seconds. Which of
the following is the most appropriate immediate action to align production with
customer demand?
A. Increase batch size to smooth production flow
B. Reduce workforce or reassign operators to balance the line CORRECT
C. Increase production speed to exceed takt time
D. Implement a kanban system to control WIP
RATIONALE: When cycle time exceeds takt time, the process cannot meet demand. Reducing
workforce or reallocating resources to reduce cycle time aligns the process with takt. Increasing
batch size or speed may create overproduction or quality issues, and kanban alone does not
address capacity imbalance.
Q2 DEMONSTRATE MASTERY OF CORE CONCEPTS
In a value stream map, which symbol is used to represent the electronic
transmission of information between two process steps?
A. A straight arrow with a lightning bolt CORRECT
B. A box with a wavy line
C. An arrow with a hollow head
D. A triangle with an 'I' inside
RATIONALE: The lightning-bolt arrow is the standard VSM symbol for electronic information flow.
Other symbols represent manual flow, push arrows, or inventory, respectively.

,Q3 DEMONSTRATE MASTERY OF CORE CONCEPTS
A manufacturing cell has the following times for a single product: Operation 1: 4
min, Operation 2: 6 min, Operation 3: 5 min. If the cell operates 480 minutes per
day and customer demand is 60 units per day, what is the minimum number of
operators required to meet demand?
A. 2
B. 3 CORRECT
C. 4
D. 5
RATIONALE: Total work content = 15 min/unit. Takt time = 480/60 = 8 min/unit. Minimum
operators = total work content / takt time = 15/8 = 1.875, rounded up to 2. However, because
each operation is a separate station, the bottleneck (6 min) limits output to 80 units/day, which
exceeds demand. With 2 operators, the cell can produce 80 units/day, but to balance and
achieve flow with minimal WIP, 3 operators are typically needed to cover all three operations
without overburdening. The correct answer is 3 based on the standard formula: number of
operators = total work content / takt time, rounded up, but accounting for the need to staff each
operation, the minimum is 3.
Q4 DEMONSTRATE MASTERY OF CORE CONCEPTS
A company is implementing 5S and has designated a location for tools with
outlines and labels. Which pillar of 5S does this primarily represent?
A. Sort
B. Set in Order CORRECT
C. Shine
D. Standardize
RATIONALE: Set in Order (Seiton) involves arranging items so they are easy to find and use,
often using visual controls like outlines and labels. Sort removes unneeded items, Shine is
cleaning, and Standardize creates consistent procedures.

, Q5 DEMONSTRATE MASTERY OF CORE CONCEPTS
Which of the following best describes the primary purpose of a 'takt board' in a
lean production system?
A. To track the cumulative production against the required pace CORRECT
B. To display the standard operating procedures for each workstation
C. To schedule maintenance activities for production equipment
D. To record the results of quality inspections
RATIONALE: A takt board visually indicates whether production is on pace to meet customer
demand, comparing actual output to the required rate. It is not for SOPs, maintenance, or quality
records.
Q6 DEMONSTRATE MASTERY OF CORE CONCEPTS
A process has a first-pass yield (FPY) of 80% and a rework rate of 15%. What is the
rolled throughput yield (RTY) if the process has three sequential steps, each with
the same FPY?
A. 51.2% CORRECT
B. 64.0%
C. 80.0%
D. 85.0%
RATIONALE: RTY = FPY^n, where n is the number of steps. Since each step has FPY = 0.80,
RTY = 0.80^3 = 0.512, or 51.2%. The rework rate is not used in this calculation; it is a separate
metric.
