Difficulty: Easy
Correct Answer: Any one of these, depending on the purpose
Explanation:
Introduction / Context:
Work study combines method study (to improve how work is done) and time study (to establish standards). Different tools are applied depending on whether we analyze flow, schedule, or measure task durations.
Given Data / Assumptions:
Concept / Approach:
Process charts (outline, flow, two-hand) document present methods and reveal non-value-adding steps. Planning charts (e.g., Gantt) assist in sequencing and visualization. Stopwatch time study measures task elements to set standard times. Any of these may be employed appropriately in a work study program.
Step-by-Step Solution:
Define the problem (method vs. timing).Select the tool: process chart for method, stopwatch for timing, planning chart for schedule and coordination.Apply and iterate improvements.
Verification / Alternative check:
Improved throughput and reduced cycle time after method changes validate correct tool choice.
Why Other Options Are Wrong:
Restricting to one tool ignores the dual nature of work study; PMTS is useful but not the only acceptable method.
Common Pitfalls:
Confusing scheduling charts with time standards; failing to validate new methods before timing.
Final Answer:
Any one of these, depending on the purpose
