Determination of the Actual Time and Frequency of Activity
The first step is to determine how long the activity affected by repacking currently takes on average. This could be, for example, a stop in the picking process or the packing of a pre-picked pallet.
A
Motion-Mining®
In Motion-Mining® projects, the time for a process step can be determined in different ways. For the time per stop in order picking, the time per trip and the number of stops per trip can be determined and divided. For other process steps, the time can be determined by the total time in the region and the number of orders per day. Similarly, it can be seen how often the process step occurs.
B
Process Observation and Time Recording
In process monitoring, the time and frequency spent on a process step can be recorded using a stopwatch or app.
C
WMS Data Analysis
In order picking, for example, the time per stop can be determined by the average time per trip and the average number of items per trip. The average number of items then also corresponds to the frequency.

Define the Target Time of the Activity
The repacking effort is usually the difference between the target effort and the actual effort. Therefore, the next step is to determine the target effort.
A
Process Observation and Time Recording
For process monitoring, a stopwatch or app can be used to record the required time.
B
MTM Process Modelling
The MTM lists contain values for various activities.

RoI Calculation
To calculate the RoI, the frequency must be multiplied by the difference between actual and target time and then scaled to the total number of employees and working days. This is set against the cost of the measure.
