Answer: C. Work measurement. Work study includes systematic method improvement and work measurement.
Method study seeks the best way to do what?
A Measure temperature
B Select a supplier
C A task
D Calibrate a gauge
Answer: C. A task. Method study records and critically examines work to develop improved methods.
Time study establishes task time using what?
A Observed work cycles
B Demand forecasts

D Machine drawings
Answer: A. Observed work cycles. Time study observes task elements and applies performance rating and allowances.
Standard time includes normal time plus what?
A Machine capacity
B Allowances
C Scrap count
D Material density
Answer: B. Allowances. Standard time accounts for personal needs, fatigue and unavoidable delays.
Predetermined motion-time systems estimate time from what?
A Machine purchase cost
B Basic human motions
C Product demand
D Supplier lead time
Answer: B. Basic human motions. PMTS assigns times to defined motions without timing each full task directly.
Work sampling uses observations taken at what times?
A Fixed cycle only
B Shift start only
C Random times
D After every unit
Answer: C. Random times. Random observations estimate the proportion of time spent on activities.
A flow process chart records work sequence and what?
A Only employee wages
B Product color
C Market demand
D Process delays and storage
Answer: D. Process delays and storage. Flow process charts capture operations, transport, inspection, delay and storage.
A two-handed process chart tracks motions of which limbs?
A Left and right hands
B Both feet only
C Two operators only
D Two machines only
Answer: A. Left and right hands. The chart studies simultaneous hand motions for manual tasks.
Motion economy seeks to reduce what?
A Product quality
B Work content value
C Operator skill
D Unnecessary motions
Answer: D. Unnecessary motions. Principles of motion economy improve work by eliminating avoidable movements.
Ergonomics fits work to what?
A Machine speed only
B Factory floor color
C Human capabilities
D Supplier location
Answer: C. Human capabilities. Ergonomics adapts tasks, tools and environments to people.
Workplace fatigue can result from high force and what?
A Low inventory
B Repetition
C Short lead time
D Good posture
Answer: B. Repetition. Repetitive work, force, awkward posture and insufficient recovery can cause fatigue.
Cycle time is time between successive what?
A Supplier orders
B Machine failures
C Inspection audits
D Unit completions
Answer: D. Unit completions. Cycle time is the elapsed time between consecutive finished units.
Takt time is available time divided by what?
A Number of workers
B Machine count
C Batch size
D Customer demand
Answer: D. Customer demand. Takt time sets the pace required to satisfy customer demand.
Line balancing assigns work to stations within what target?
A Cycle time
B Inventory turnover
C Lead time
D Inspection limit
Answer: A. Cycle time. A balanced line keeps station workload at or below required cycle time.
The bottleneck station determines what line rate?
A Maximum throughput
B Minimum quality
C Material density
D Tool hardness
Answer: A. Maximum throughput. The slowest constrained station limits overall production rate.
Utilization compares busy time with what?
A Lead time
B Cycle time only
C Available time
D Demand forecast
Answer: C. Available time. Utilization is the fraction of available time a resource is busy.
Overall equipment effectiveness combines availability, performance and what?
A Quality
B Inventory
C Safety stock
D Setup cost
Answer: A. Quality. OEE multiplies equipment availability, performance and quality rates.
A process layout groups equipment by what?
A Product sequence
B Similar function
C Customer type
D Worker height
Answer: B. Similar function. Functional layouts place similar processes or machines together.
A product layout follows what arrangement?
A Machine family
B Operation sequence
C Department budget
D Random routing
Answer: B. Operation sequence. Product layouts arrange stations in the order required to make the item.
A fixed-position layout keeps what stationary?
A Workers
B Tools
C Material handling equipment
D Product
Answer: D. Product. Large products remain in place while people and equipment move to them.
Material handling aims to move material safely and how?
A With maximum distance
B Without layout planning
C Efficiently
D Only by hand
Answer: C. Efficiently. Material-handling systems reduce cost, damage and unnecessary movement.
A conveyor provides what material-flow characteristic?
A Continuous movement
B Random storage
C Manual lifting only
D Zero energy use
Answer: A. Continuous movement. Conveyors move items along a defined path, often continuously.
5S begins with which workplace step?
A Standardize
B Sustain
C Shine
D Sort
Answer: D. Sort. The first 5S step removes unnecessary items from the workplace.
