,Q1 DEMONSTRATE MASTERY OF CORE CONCEPTS
In the context of Lean accounting, which of the following best describes the
primary purpose of a 'value stream income statement'?
A. To allocate all manufacturing overhead costs to individual products based on direct labor
hours
B. To report the profitability of a value stream by grouping revenues and costs directly associated
with that stream, excluding allocated overhead CORRECT
C. To provide a detailed breakdown of standard cost variances for each product within a value
stream
D. To satisfy external financial reporting requirements by showing inventory valuation in
accordance with GAAP
RATIONALE: A value stream income statement presents revenues and costs directly attributable
to a value stream, avoiding traditional overhead allocations that can distort profitability. It
supports Lean decision-making by highlighting the actual financial impact of value streams,
unlike GAAP-based statements which focus on inventory valuation and standard costing.
Q2 DEMONSTRATE MASTERY OF CORE CONCEPTS
A manufacturing cell is redesigned to produce a family of parts in a continuous
flow. The cell operates 8 hours per shift, 2 shifts per day. The takt time is 120
seconds per part. What is the maximum daily customer demand that this cell can
satisfy?
A. 240 parts
B. 480 parts CORRECT
C. 960 parts
D. 1920 parts
RATIONALE: Total available time per day = 8 hours × 2 shifts × 3600 seconds = 57,600 seconds.
Maximum output = 57, = 480 parts. Thus, the cell can meet a maximum daily demand
of 480 parts at takt time.

,Q3 DEMONSTRATE MASTERY OF CORE CONCEPTS
Which of the following is a key principle of the Toyota Production System (TPS)
that distinguishes it from traditional mass production?
A. Producing in large batches to maximize machine utilization
B. Emphasizing worker autonomy to stop the line when defects are detected (Jidoka)
CORRECT
C. Relying on complex computer systems to schedule production
D. Focusing on maximizing inventory levels to buffer against demand variability
RATIONALE: Jidoka, or automation with a human touch, allows workers to stop production
immediately upon detecting abnormalities, preventing defects from propagating. This is a
cornerstone of TPS, contrasting with mass production's emphasis on continuous operation and
large batches.
Q4 DEMONSTRATE MASTERY OF CORE CONCEPTS
In the context of Lean leadership, which of the following behaviors is most critical
for sustaining a culture of continuous improvement?
A. Enforcing standardized work through strict supervision
B. Celebrating individual achievements and rewarding the top performers
C. Demonstrating 'go and see' (Genchi Genbutsu) by personally observing processes and
engaging with frontline employees CORRECT
D. Delegating all improvement initiatives to a dedicated Lean team
RATIONALE: Lean leadership requires leaders to be actively involved on the gemba,
understanding processes firsthand, and coaching employees. This fosters a culture of
improvement, whereas delegation and top-down enforcement undermine employee engagement
and problem-solving.

, Q5 DEMONSTRATE MASTERY OF CORE CONCEPTS
A company is implementing 5S in its warehouse. After sorting (Seiri), the team
sets standards for how often items should be placed in designated locations
(Seiketsu). This standardization is primarily intended to:
A. Eliminate the need for visual controls
B. Ensure that the first three S's are consistently maintained CORRECT
C. Reduce the time required for daily cleaning (Seiso)
D. Make it easier to identify nonstandard conditions during audits
RATIONALE: Seiketsu, the fourth S, involves standardizing best practices to sustain the gains
from Sort, Set in Order, and Shine. It creates consistent procedures that help maintain order and
cleanliness, preventing regression to old habits.
Q6 DEMONSTRATE MASTERY OF CORE CONCEPTS
Which of the following is a primary benefit of implementing a pull system in a
supply chain?
A. It reduces the need for demand forecasting
B. It increases work-in-process inventory levels to ensure smooth flow
C. It produces goods based on actual customer demand, reducing overproduction CORRECT
D. It allows for larger batch sizes, lowering setup costs
RATIONALE: Pull systems trigger production based on downstream consumption, aligning output
with real demand. This minimizes overproduction, reduces excess inventory, and improves
responsiveness, unlike push systems that forecast and produce in advance.
