Issue analysis aids strategic intelligence efforts by helping companies anticipate changes in their external environments and shape public policy. It involves identifying issues, analyzing them based on factors like impact and probability, and selecting issues for action. Key steps are issue identification through methods like media scanning, assessment using matrices to evaluate impact and probability, and selecting a response strategy like altering behavior, contesting the issue, or ignoring it. Issue analysis supports decision-making by prioritizing issues and recommending where to focus resources.
