Work out line output per day instantly with clear inputs, formula shown and shareable results.
Line output is available operator minutes times efficiency divided by garment SAM. The gap between that and the 100%-efficiency figure is the improvement headroom, and it is usually large — most sewing lines run at 50-70% efficiency, so output can rise substantially without adding operators.
Line output
Output = operators x working minutes x efficiency / SAM
Line balance, operator skill on the specific operation, style change frequency, machine breakdowns, and quality rework. New styles typically start at 30-40% and climb over one to two weeks.
Only if the line can be re-balanced to use them. Adding operators to an unbalanced line raises WIP and idle time without raising output.
