Exam 19: Work Measurement, Learning Curves, and Standards

Unavoidable delays should not be included in time studies.

A 90% learning curve implies faster learning than an 80% learning curve.

The learning curve does not apply to supervisory personnel, some skilled craftspeople or jobs that have non-repetitive job tasks.

For a time study, it is assumed the distribution of task times follow a Poisson distribution.

Regression analysis is used to predict times based on different attributes of work.
