I use identity theory to conceptually develop board identities that help us explore and understand board behavior. I develop two specific board identities, which I label board’s organizational identity and board’s contextual identity and develop assertions about board behavior that can be expected based on these identities. A key contention is that each type of identity helps board conceptualize its role holistically and develop appropriate behavior routines, and a lack of a coherent and strong identity leads to poor discharge of board’s duties.
