A high-risk, high reward tool for law departments is the so-called Johari window. The Johari window has four quadrants (panes): personal characteristics known by the person or not known by them are in two panes matched against those characteristic known by others (blind spots) and not known by others (hidden agendas). Hence the 2-by-2 window has 4 panes.

Johari sessions can also unleash negative output (blind spots and hidden agendas and emotional confrontations.
