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/Approach
In 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.
