Question: Which patterns and rules are derived?
Answer: A request for information act should be issued early in a conversation, followed by an answer, informative statement, or apology towards the end of the conversation,  offering extra help at the end of a conversation, or thanking the customer yields more satisfied customers, and more resolved problems , asking yes-no questions early-on in a conversation is highly associated with problem resolution (ratio 3:1), but asking them at the end of a conversation has as similarly strong association with unsatisfied customers, Giving elaborate answers that are not a simple affirmative, negative, or response acknowledgement (i.e. Answer (Other)) towards the middle of a conversation leads to satisfied customers that are not frustrated, requesting information towards the end of a conversation (implying that more information is still necessary at the termination of the dialogue) leads to unsatisfied and unresolved customers
