Standard time for an operation is formally defined as ____________________?
Show answer Hide answer
Answer: A. normal time + allowances
Explanation
Standard time for an operation is formally defined as normal time plus appropriate allowances. Normal time measures the adjusted pace of a worker executing tasks without accounting for fatigue. Adding allowances for personal needs and fatigue yields the realistic standard time for scheduling. Time study analysts observe workers using stopwatches and rate their performance against standard paces. Allowances compensate workers for unavoidable delays, fatigue, and necessary personal biological breaks. Standard time serves as the fundamental basis for wage incentives, costing, and production scheduling.
Manufacturing engineers rely on accurate standard times to quote production costs and delivery dates. Unrealistic standard times lead to worker dissatisfaction or missed production targets in the factory. Proper allowance calculations ensure workers can maintain productivity throughout a full working shift. Including idle time in standard time calculations would reward inefficiency rather than actual work. Defining standard time as only normal time ignores necessary fatigue and personal allowances. Claiming none of the above is wrong because normal time plus allowances is the correct definition.
