Second, he needed to translate these forecasts into staffing levels that would make an adequate trade‐off between teller idleness and customer waiting. Third, he needed to translate these staffing levels into individual teller work assignments‐who should come to work when. The last two parts of the problem require analysis tools that we have not covered. However, you can help James with the first part‐forecasting.
