How to forecast in times of uncertainty

How can they arrive at a realistic sensible forecast in such times of uncertainty?
Any forecast of the future will be wrong-but we can get an idea of where we are headed. Provided we are clear about our assumptions – track the main variables and adapt our response accordingly.
The approach we have adopted is not complex but is detailed. Recognise that the lockdown will affect all departments differently-so forecast at department level then aggregate the firm.
Start with the budget income for each department for the coming year monthly, then ask a simple question. For that department, for that month, what % of our budget do we expect to bill? Best done to the nearest 10%. A simple spreadsheet with a few calculations can be very powerful.
Then track the accuracy of the forecasts and update them regularly by tracking the % achieved each month against a predetermined standard then assess the impact in each area to make staff and resource decisions accordingly.
