Step-by-step explanation:
The most important consideration a manager must make when forecasting the number of staff to hire and schedule is the demand for the organization's product or service.
Managers need to analyze the current and future demand for their product or service to determine the appropriate staffing levels. They must consider factors such as market trends, customer demand, and sales projections.
For example, if a company expects a surge in demand for their product, the manager may need to hire additional staff to meet customer needs. On the other hand, if demand is expected to decline, the manager may need to reduce staffing levels to avoid unnecessary costs.
