About the teaching case

Dive into the online business game ‘The Blue Connection’ together with your students for a case study on introducing circularity into supply chains. In ‘The Blue Connection’, students take on the role of ‘circular turnaround manager’ and are asked to improve the circularity in the value chain. Accompanied by a Harvard-style Teaching Case, students are faced with a supply chain challenge: an e-bike manufacturer that wants to modify its linear supply chain to become more circular. Eventually, the goal of this game is to come up with possibilities to optimize the circularity in this company.

Students need to brainstorm about circular flows and actions based on known business models. The learning outcome is for students to have an understanding of the principles of circular supply chain management.


This case is designed for Circular Supply Chain modules and suitable for supply chain courses. During the case, students are challenged to learn:

  • Which steps a company could take in order to become circular
  • Which circular flows and activities could be implemented in certain scenarios
  • Which circular flows and activities could be implemented in certain scenarios
  • Which accompanying business models can support a circular supply chain
