Which of the following does NOT belong to the problem-solving model?

The problem-solving model typically consists of several key steps that guide individuals or teams in addressing challenges and making informed decisions. The first steps usually involve identifying the problem, generating potential solutions, evaluating those solutions, making a choice, and then implementing the chosen solution. The sequence often culminates in feedback gathering to assess the effectiveness of the solution.

In this context, feedback gathering is often seen as part of the final step following the implementation. It serves to inform whether the implemented solution effectively addressed the problem, thus playing a critical role in revising actions or re-evaluating solutions as necessary. Therefore, while feedback is essential in the problem-solving process, it is not typically classified as a distinct phase within the core model, unlike the other aspects listed in the choices.

On the other hand, problem identification is crucial as it sets the stage for the entire process, implementation becomes critical once a solution is chosen, and solution evaluation and choice are vital for ensuring that the adopted solution is the most suitable for the identified problem. Each of these steps represents an integral part of the structured approach to problem-solving, while feedback gathering is more about assessing outcomes rather than being a core step of the model itself.
