Illustration of a collaborative process between modellers and stakeholders/decision makers.
Each group brings something to the table at different time points. The best modelling result with eventual impact is usually only obtained in collaboration. Although the process is depicted as linear, in practise each node may connect back to stakeholders and modellers for continuous dialogue and discussion; policy implementation can also be reevaluated in light of evidence.
