ESTJ

ESTJ (Extroverted Sensing Thinking Judging) is one of the sixteen personality types from the Myers-Briggs Type Indicator (MBTI), and the Keirsey Temperament Sorter.

Referring to Keirsey, ESTJs belong to the temperament of the guardians and are called "Supervisors".

Myers-Briggs Characteristics
ESTJs are practical, realistic, and matter-of-fact, with a natural head for business or mechanics. Though they are not interested in subjects they see no use for, they can apply themselves when necessary. They like to organize and run activities. ESTJs make good administrators, especially if they remember to consider others' feelings and points of view, which they often miss.

Keirsey Characteristics
According to Keirsey, ESTJs, or "Supervisor Guardians", are civic-minded individuals who dedicate themselves to maintaining the institutions behind a smooth-running society. They are defenders of the status quo and strong believers in rules and procedures. Outgoing, they don't hesitate to communicate their opinions and expectations to others.

MBTI cognitive functions
The attributes of each personality form a hierarchy. This represents the person's "default" pattern of behavior in their day to day life. The Dominant is the personality type's preferred role, the task they feel most comfortable with. The auxiliary function is the role they feel the next most comfortable with. It serves to support and expand on the dominant function. One of these first two will always be an information gathering function (sensing or intuition) and the other will be a decision making function(thinking or feeling) in some order. The tertiary function is less developed than the Dominant and Auxiliary functions, but develops as the person matures and provides roundness of ability. The inferior function is the personality types Achille's heel. This is the function they are least comfortable with. Like the tertiary function, this function strengthens with maturity.
