We will introduce a digital app that enables sales employees in the butchery, cheese, and fish departments to analyze their average receipt. Our study’s experimental design consists of a control group (CON) and two randomly assigned treatment groups (MED, DIS). The control group and the treatment groups each receive different reports in the digital app, which are updated every two weeks. The intervention will take place in two phases. In phase one, employees of all groups receive the basic design of the control group over a period of one month (already started in October 2021). In the experimental phase (second phase), treatment groups are informed of the median performance (MED) and performance deciles (DIS) of employees in their department across comparable stores (of similar size) over a period of 3 months. The reports are completely anonymous and do not allow conclusions about individual performance data of peers.
Control Group (CON)
To avoid possible contamination effects due to the implementation of the app and effects that are driven simply by increased attention on the new performance metric employees in the CON group receive a report about their average receipt too. They will be informed about their average receipt of the past two weeks as well the development of their average receipt over the last six weeks. In order to be able to distinguish the effect of the treatments from the effect of the introduction of the app, employees of all groups receive only the design of the CON group in the first phase of the experiment.
Treatment Median (MED)
Employees in the MED treatment group receive a report similar to the control group. In addition, they receive the median of employees from their department from comparable stores over the last two weeks. Below the chart on the median of the comparison group, employees are informed in a sentence whether their average receipt exceeds the median average receipt of the comparison group or not.
Treatment Distribution (DIS)
Employees in the DIS treatment group receive a report similar to the control group. In addition, they receive the average receipt of the performance deciles of employees from their department from comparable stores over the last two weeks. Below the graph on the deciles of the comparison group, employees are informed in a sentence to which decile they belong.
