b. identifying capacity gaps.
c. developing alternative strategies for addressing gaps.
d. selecting the strategy which minimizes the associated costs.
e. choosing appropriate alternatives.
3. Qualitative forecasting methods are used when:
a. no quantitative data are available.
b. historical data is available.
