Accordingly the information can be categorized as: strategic information, managerial information and operational information.Strategic information is the information needed by top most management for decision making. For example the trends in revenues earned by the organization are required by the top management for setting the policies of the organization. This information is not required by the lower levels in the organization. The information systems that provide these kinds of information are known as Decision Support Systems.

Gather Information: Collect relevant data and insights to understand the context and implications. Evaluate Alternatives: Consider various options and weigh their pros and cons. Make the Decision: Choose the best alternative based on the evaluation. Implement and Review: Execute the decision and assess its outcomes to inform future decisions.

This involves identifying the potential scenarios that could result from different choices and estimating the likelihood of each scenario occurring. Additionally, understanding the costs and benefits linked to each outcome will help in calculating the expected value for each option, allowing for informed decision-making. Finally, any uncertainties or risks associated with the outcomes should also be considered.
