What factors might need to be considered when forecasting?
Organisations face particular problems in forecasting their income flow. Voluntary donations depend upon support for the mission, but public concern about an issue may wane. Other intangible factors, such as changes in legislation, can compound the difficulty of making projections. The forecaster first studies current income and spending, asking if they can be sustained at present levels and then works through forecasts for each type of future income and expenditure.
