Guidelines for Implementing a Forecast
All managers of an MNC should rely on the same exchange rate forecasts otherwise one manager may be making decisions based on forecasted appreciation of a currency, while another manager may be making decisions based on forecasted depreciation of that currency.
MNCs may complement their forecast by hiring forecasting services to obtain exchange rate forecasts. No guarantee that a forecasting service will generate more accurate forecasts that those the MNCs can generate on their own
