A company plans to launch a customer management system. The department head says, "Top companies in the industry are all using this system, and it is recommended by a well-known expert, so we should definitely use it too." Which of the following two evaluations are the most accurate?

Answer: AC

• AThe fact that top companies are using it only shows the system is somewhat popular; it does not prove it is suitable for our company's processes, scale, and cost.✓ Correct. An appeal to popularity only shows popularity, not validity; whether it fits requires evaluation based on the company's specific conditions.
• BSince a well-known expert recommends it, the system must have been rigorously verified, so we can adopt it directly without further evaluation.✗ Incorrect. This is a classic appeal to authority, treating the expert's opinion as the end of reasoning; one should check whether the expert is relevant, whether there are conflicts of interest, and consider other evidence.
• CEven if what top companies and the expert say is true, we still need to understand the system's actual cost, staff capability, and migration risks in our company's scenario.✓ Correct. Authority and popular opinion serve only as one piece of evidence; the real decision requires looking at specific applicability, cost, and consequences.
• DTop companies have large scale and high management standards, so their choices must be right; we should just imitate them.✗ Incorrect. This replaces evidence with the status of "top companies," assuming they cannot be wrong; in fact, overall strength does not mean every specific purchase decision is suitable for other companies.
