ESTJs communicate in a direct, assertive, and action-oriented manner, focusing on getting things done efficiently. ISTJs communicate more carefully and precisely, preferring to think things through before speaking.
The challenge is that ESTJ may sometimes move too quickly for the more deliberate ISTJ, while ISTJ's need for thoroughness may frustrate ESTJ's desire for quick decisions. Success comes from ESTJ allowing time for ISTJ's input and ISTJ being more willing to voice opinions sooner.
