Simulation models were not presented upfront. It is important
to highlight that, for the two first workshops involving both product A and B, the researchers decided not to present the simulation model. The discussions were based only on the presented simulation results and statistical analysis of data. Only at the third workshop, the researchers presented the simulation model and outputs from the experiments involving the different scenarios. At first, stakeholders appeared a little confused on how to read the model, maybe because of the system dynamics notation. Later, some stakeholders apparently changed their opinion with the simulation tool and its possibility of
anticipating scenarios.
