How is demand calculated?
1) Gooroo Planner starts by measuring demand in the past period, using one of two methods:
a) (default) activity plus growth in waiting list over the past period, with an adjustment for short-notice removals, if any, or
b) additions minus removals;
you can choose which method you want to use either service-by-service (in your dataset) or generally (via the dataset settings), and your choice should depend on which data quality you trust the most. A full explanation of the maths can be found in the Publications section of our website, in the Planner documentation.
2) Planner projects past demand into future demand either:
a) taking account of trend demand growth, the different lengths of the past and future periods, and seasonality; or
b) if this is an elective service and driven by outpatient knock-ons, then past demand is inflated to future demand by the same proportion as past outpatient activity increases to future outpatient activity;
3) it adds any extra demand you specify in your dataset (using the field FutExtraDem).Return
