The correct answer is: A. control decisions.
Computer information systems are most successful in providing information for control decisions. Control decisions are made on a regular basis to ensure that the organization is operating as planned. They are typically made by lower-level managers and employees. Computer information systems can provide timely and accurate information that helps managers to monitor performance, identify problems, and take corrective action.
Planning decisions are made to set goals and objectives for the organization. They are typically made by middle-level managers. Computer information systems can be used to develop and analyze plans, as well as to track progress towards goals.
Strategic decisions are made to determine the long-term direction of the organization. They are typically made by top-level managers. Computer information systems can be used to analyze the environment, identify opportunities and threats, and develop strategies to achieve the organization’s goals.
Nonprogrammable decisions are made in response to unique or unusual situations. They are typically made by top-level managers. Computer information systems are not well-suited for making nonprogrammable decisions because they require human judgment and creativity.
In conclusion, computer information systems are most successful in providing information for control decisions. They can also be used to support planning and strategic decisions, but they are not well-suited for making nonprogrammable decisions.
