This is exactly the difference between beginners or novices and experts. As you grow in any field, your incisiveness at asking better questions improves.

If you're not asking the right questions, how can you get the right answers, or results? But it's not a right question, wrong question binary thing, it's a big fuzzy area of improvement.

Often people believe they want a certain service. They might be expert in one field, but not in the area they need work done. Some providers simply give them what they ask for and there's nothing inherently really wrong with that, but the best in their field quickly look beyond the request to address the real need. In so doing they'll as often as not actually talk the client out of spending so much money but gently educate the client as well as give a solution that is a better fit and more future proof.

Instead of just giving what's asked for, taking the money and running, it can be far better in the long run, to give genuine insight and value. That's the kind of thing that breeds real loyalty and respect.

Better evaluations tend to lead to better questions which often result in better work.
