Final answer:
Decisive leadership is not one of the widely recognized concerns with the problem identification process; instead, it is considered beneficial for effectively identifying policy issues.
Step-by-step explanation:
The question is asking about the concerns with the problem identification process, a step in the public policy process. The most widely recognized concerns include stakeholder framing, solution-focused problems, adequate time and resources, and perceptual defense, as these can all interfere with correctly identifying the true nature of the policy issue. Decisive leadership is typically not viewed as a concern, but rather as beneficial for the problem identification process. Therefore, the correct answer is (b) Decisive leadership.
