Final answer:
The manager should use a Decision Support System (DSS) to assess the impact on production schedules if sales were to double in November. This type of system is ideal for simulating scenarios and evaluating their outcomes on production processes.
Step-by-step explanation:
If a manager wants to understand the impact on production schedules if sales doubled in the month of November, the most appropriate information system to use would likely be a Decision Support System (DSS). Decision Support Systems are interactive software-based systems intended to help managers in decision-making by providing data, tools, and models to solve unstructured problems.
In this case, a DSS would be beneficial as it would allow the manager to simulate various scenarios, including one where sales are doubled, and assess the outcomes on production schedules. This involves incorporating various factors like current inventory levels, production capacity, workforce availability, and supplier readiness, among others.
Other information systems like Transaction Processing Systems (TPS), Management Information Systems (MIS), or Enterprise Resource Planning (ERP) systems might also be involved in the process to provide necessary data or integrate various business processes. However, the DSS specifically targets decision-making processes involving complex, non-routine problems, making it the best fit for this question's requirements.
