This is the quintessential dependable, responsible, task-driven team—dutifully oriented around accountability, productivity and the bottom line.  ISTJ teams see their tasks and goals in terms of facts and tangible realities, which they prefer to deal with objectively. Their interactions tend to be structured, scheduled, and ordered and the collective preference for Introversion can make the team appear somewhat cool and detached.  ISTJ teams tend to be focused, no-frill affairs—often seen as compulsive, hard-charging, capable and true to their word. ISTJ teams tend to be slow to change until they see the practical value in making course corrections.
