Use of a discrete-event simulation in a Kaizen event: A case study in healthcare.

•Reducing patient delays with discrete event simulation (DES) in an oncology clinic.•Participative simulation (PS) use people creativity to improve patient pathways.•PS combined with DES may support participants during the Kaizen to test ideas.•Using DES during the Kaizen event fosters quick implementation.•Quick implementation of changes after the Kaizen is crucial to guaranty its success.
