Setting standard time in complex job systems Select the most suitable method for determining <em>standard time</em> in a complex, varied job environment where direct timing is difficult. Choose the best technique.

Concept/ApproachIn complex or low-repeat environments, standard data (pre-determined element times gathered from prior studies or PMTS libraries) are combined to estimate the time for new jobs without re-timing every operation.

Why others are less suitable• Stop watch study suits repetitive, short, stable cycles.• Micromotion (e.g., therbligs) is too granular for broad complex jobs and is costly.• Grouping timing is coarse and less rigorous than a standard data system.
