CELEMI PartnerStock™


Are you struggling with inventory levels and lead times? Do your colleagues continue cemented behaviors – despite directives, training, and kickoffs? Then Celemi PartnerStock™ might be for you.

Celemi PartnerStock™ is a competitive and interactive simulation. Participants are grouped into teams, and presented with life-like, inventory related dilemmas and challenges. They have to prioritize their limited resources to handle the challenges.  The goal is to optimize inventory levels while managing customer satisfaction and profit. The most successful team wins the competition.

The discussions and decisions within the teams, the competition between the teams, and the debriefs in plenum create a learning environment which is highly engaging, competitive, interactive, and fun. The participants experience a significant peer-to-peer learning, make clear links to their real-life dilemmas, and apply research results and scientific models.
