Which of the following is NOT one of the basic steps in problem-solving?

The process of problem-solving generally involves a structured approach, typically encompassing steps like identifying the problem, analyzing the root causes, and confirming the results after implementing a solution.

Investigating the market, while still an important activity in certain contexts such as business strategy or product development, does not fit into the traditional, core steps of problem-solving. The essence of problem-solving is focused on defining and resolving specific issues rather than exploring external factors like market conditions. Thus, including investigation of the market would be seen as a broader research activity rather than a fundamental step dedicated to solving a specific problem.

In contrast, identifying the problem ensures that the focus is clear, analyzing the problem involves understanding the factors contributing to the issue, and confirming the results is necessary to verify that the solution has worked effectively. All these steps are integral to developing effective solutions, while market investigation is more about understanding the environment surrounding a product or service rather than directly addressing an organization's specific internal challenges.
