STEP 3: Host a workshop
... for assumption-building with key stakeholders
Given the special case of forecasting for NUMs, it is recommended that a workshop be held with various key stakeholders, including those in the public and private sectors if relevant, to lay out the forecasting assumptions for the particular NUM. Bring to the table information gathered from steps 1-2. Determine the key factors that are expected to influence demand/uptake of the method as a group. Agree on how the forecast will be calculated and document all assumptions that will be made to yield the forecast.
