It is important to maintain and improve quality to earn customer satisfaction.
We should maintain Focus, knowledge, skills, response, and handling at high level and in a balanced manner.
If one of them is weaker than others, it lowers the whole.
So if you have excellent response but poor knowledge, you cannot achieve high quality.
Likewise, if you have good knowledge but poor response, you have no quality.
You need to take the balance of the whole by raising the weaker (or lower) element.
If you can deal with you customers at the high level, it leads to higher customer satisfaction.
