Step assessments are a necessary part of time-motion studies.

• A. False
• B. Sometimes
• C. True
• D. Not specified

Answer: (C)

Breaking a task into discrete steps and timing each one is the foundation of time-motion analysis. This level of detail lets you calculate precise standard times, compare different work methods, and pinpoint exactly where time is spent or wasted. If you only look at the total duration, you miss which parts of the process drive the time or how variability arises between cycles or operators. By assessing each step, you create a clear, repeatable model of the work that supports targeted improvements and reliable standards. For these reasons, step assessments are a necessary part of time-motion studies.
