What term refers to the action or process in solving a problem?

The term that refers to the action or process in solving a problem is "solution." A solution specifically denotes the answer or the means of solving a problem after the process of analysis, brainstorming, or deliberation has taken place. It embodies the outcome arrived at through various methods of examination and thought—a culmination of a problem-solving process.

While resolution, decision-making, and implementation are all vital components of problem-solving, they represent different aspects of the overall process. Resolution often denotes the final outcome or agreement reached, while decision-making refers to the cognitive process of making a choice among various options. Implementation, on the other hand, involves executing the decided solution. Therefore, the term "solution" aptly captures the essence of arriving at an answer to a problem, emphasizing not only the end result but also the various strategies that contribute to finding that answer.
