Max Holder GmbH faced the following challenges

Max Holder GmbH manufactures and sells multifunctional vehicles for the most diverse and demanding tasks worldwide. This includes power and maneuverability in the smallest of spaces, such as sweepers, mowers, or snow ploughs for snow removal services in municipal applications. The Reutlingen-based company, which has been part of the Kärcher Group since 2019, also manufactures sophisticated vehicles for fruit and wine cultivation.

Holder manufactures a large and diverse number of vehicle models for many different areas of application. This posed a challenge for Holder when it came to daily staff planning and optimal assembly line balancing.

Using extensive Excel tables and PowerPoint slides, personnel scheduling was elaborately planned by hand. Resource planning was based on average values from the past and data for more precise calculations and better productivity of employees was not available.

The result: Personnel scheduling was tedious, employees were not being optimally utilized and assembly processes were not being ideally planned.
