Work Measurement

Work Measurement consists of various Industrial Engineering techniques including Time Study, Motion Study, Predetermined Motion Time System (PMTS), and MODAPTS.

What is Time Study?
time study

Time study is a work measurement technique consisting of careful time measurement of the task with a time measuring instrument, adjusted for any observed variance from normal effort or pace and to allow adequate time for such items as foreign elements, unavoidable or machine delays, rest to overcome fatigue, and personal needs.

What is PMTS?

Unlike time studies, in which an analyst uses a stopwatch and subjectively rates the operator's effort to calculate a standard time, a PMTS requires that the analyst break apart the process into its component actions, assign time values to each action, and sum the times to calculate the total standard time.

What is MODAPTS?

MODAPTS stands for Modular Arrangement of Predetermined Time Standards. Unlike the MTM and MOST standards, MODAPTS uses a MOD as its basic unit of measurement (1 MOD = 0.129 seconds). However, like Basic-MOST, MODAPTS uses a coding technique that consists of a letter and an integer number (all but 1 code), where the integer numbers each represent MODS that can be easily added to determine a coded task's time.

Why Hire PMC for Work Measurement Consulting?

For over 30 years, PMC has been offering reliable and accurate work measurement services as part of its productivity improvement solutions. Starting with the automotive manufacturing industry, PMC has expanded its work measurement services to service industries such as healthcare and provided this service in conjunction with its lean and six sigma services.

PMC has several industrial engineering experts on its staff with more than 15 years of time study and work measurement experience who are MODAPTS Certified. Furthermore, PMC offers MODAPTS training, that prepares you for the Certification exam. The training is given by a Professional Certified MODAPTS Instructor through the IMA (International MODAPTS Association) at cost-effective rates.

PMC's complete Work Measurement services includes:
  • Stopwatch Study-Generally applied for continuous indirect labor studies (example: Performing a time study on a forklift truck driver for an entire shift)
  • Work Sampling Study-Generally applied to study non-repetitive tasks with long cycle times (example: maintenance operator, support personnel, etc.)
  • Predetermined Motion Time System (PMTS)
  • MODAPTS, MOST, and MTM are generally applied to study repetitive tasks, with short cycle times, involving direct labor personnel (example: assembly line operator, machine center operators, etc.)

In a system involving different types of work elements, a combined approach using stop watch time study, work sampling, and MODAPTS/MOST/MTM may be deployed to achieve the most accurate and reliable work measurement results.
