What is the man to machine ratio?
Man to machine ratio is defined as the total workforce in a factory to the total number of operational sewing machines.
Man to machine ratio widely varies depending on the organization structure. If a factory has only departments associated with garment production (i.e., cutting, sewing, maintenance, quality and IE) then this ratio will be low. On the other hand, if a factory includes the department of design & development, sampling to finishing to shipment and documentation then this ratio will be high.
How to calculate Man to Machine ratio?
To measure Man Machine Ratio (MMR) of a factory –
- First, find how many employees are there (including all manpower).
- Second, Count how many sewing machines are there. Consider only operational machines that are being used in a current month (data analysis month)
For example,
- If total manpower is 1000 and the total available machine is 500. Then Man:Machine = 1000:500 = 2:1
- If total manpower is 800 and the total available machine is 500. Then Man:Machine = 800:500 = 1.6:1
How to calculate the department-wise MMR ratio?
Instead of whole factory manpower, one can measure MMR only for the sewing department. In this case, include only those employees who work in the sewing section. Like, operators, helpers, pressmen, feeders, line checkers, table checkers, line supervisors, work-study boys, maintenance personnel, production writer, floor in-charge, etc.
Sum of (D1:D2:D3:D4….:D10) = 2
