Spot the erroneous statement concerning the practical benefits of work sampling_________________?
Show answer Hide answer
Answer: A. permits a fine breakdown of activities and delays
Explanation
Work sampling involves taking random instantaneous observations and is entirely unsuited for capturing fine breakdowns of minute activities or delays. Continuous time study using stopwatches is the correct methodological choice when a detailed breakdown of short-duration activities is required. Because observations are sampled periodically, rapid or subtle operational delays are frequently missed during work sampling studies. Work sampling is a statistical measurement technique used to estimate the percentage of time workers spend on various activities. L.H.C. Tippett originally developed work sampling under the name snapshot observation to study industrial manufacturing delays efficiently. The method relies heavily on the laws of probability to ensure that random observations yield statistically valid operational estimates.
Observing multiple machine operators simultaneously is a major practical benefit because a single observer can tour a large workshop. Work sampling calculations are mathematically straightforward, economical, and significantly less time-consuming than continuous stopwatch studies. Avoiding continuous observation significantly reduces the Hawthorne effect, minimizing the chances of obtaining misleading behavioral results.
