Determine the Proportion of Manual Wrapping
The time share for manual wrapping can be determined in different ways.
A
Motion-Mining®
As part of a Motion-Mining® project, the time share of the activity can be analyzed.
B
Process Observation and Timing
In a process observation, the proportion of time can be recorded with the help of a stopwatch or a corresponding app.
C
WMS-Analysis
In many cases, the pallet does not need to be wrapped until an order has been completed. In this case, the time to wrap a pallet can be determined by sampling. The first step is to determine the time it takes to wrap a pallet, e.g. by observing the process. The second step is to determine the average number of pallets per person from the WMS. Multiplying these two figures gives the total effort per day.

Evaluation of the Ergonomic Load
Various methods can be used to evaluate ergonomic stress. One of the most common, for example, is the Key Indicator Method (KIM). In this case with the sheet for assessing and designing physical workloads during manual handling operations (KIM-MHO).

RoI Calculation
Replacing manual wrapping can lead to both ergonomic relief and increased efficiency.
A
Ergonomics
The RoI of ergonomic improvements can be calculated, for example, by estimating the average number of sick days that can be saved as a result of the improvement.
B
Efficiency
As far as efficiency is concerned, the ROI comes from the time that can be saved by not having to wrap the pallet manually. This is in contrast to the additional time, for example due to an extra route, and the cost of the operation.
