Which group would make the decision about which solution is best

The group that would make the decision about which solution is best can vary depending on the context or problem at hand. In general, it can be a collective decision made by a team or committee consisting of relevant stakeholders or subject matter experts. This group may include individuals from different departments or functional areas within an organization, such as managers, executives, engineers, designers, marketers, and consultants. The decision-making process may involve discussion, analysis, evaluations, and consensus-building among the group members before reaching a final decision on the best solution.
