Man-days Calculation in Quality Control Services

What is Man-days in Quality Control Management?

When you talk to any third-party inspection company to get quotes for services, they will tell you that most of their quality control services are billed based on “Man-days”, which roughly amounts of working time that one certified quality inspector can do in one day, no matter in the quality inspection or factory audit services.

Most of these jobs will be done in one Man-Day, after you send detailed information including product specifications, supplier information, inspection checklist, etc., a third-party inspection company will finally confirm the actual amount of man-days needed.

How Do We Make Man-days Calculation?

Please note that for each check we calculate the working hours based on the following information and then switch to the working day required for service:

  • – Time spent at the inspection site.
  • – Traveling to and from the factory takes only half of the time. (Usually, we calculate the travel time in the morning)
  • – The working hours of each inspector are calculated separately.
  • –According to the location of our QC inspectors, we usually send the QC inspectors closest to the factory first to save more travel time for services

Many clients asked that 1 man day is equal to how many hours? will the QC inspector spend 8 hours in the factory? please check the man-days calculation construction for the time for each inspector or auditor will be counted like below, and then the customer will know the number of man-days

  • 1 Man-day: Can be up to 11 hours but the inspector left no later than 6 PM
  • 1.5 Man-days: 11-16 hours
  • 2 Man-days: 16 or more hours

Please note overtime costs will be charged if inspection delays after 6 PM.

Man-days Calculation Examples

Example 1:

Inspector travels 2 hours to the factory and spends 6 Hours for inspection at factory, and left the factory before 6 PM, that means a total of 8 hours spends for this inspection, so the total is one man-day

Example 2:

A third-party inspection company sends two inspectors, and each inspector spends 7 hours for inspection and left the factory before 6 PM, which means a total of 14 hours are counted, and the total man-day count is two man-days

Here we provided a basic recommended amount of Man-days for each service in order to keep our services at a high level of transparency, that you could learn how to calculate the man-days.
