American organizational theorist and management scholar, a central figure in the punctuated-equilibrium model of organizational change — the theory that firms alternate long "convergence" periods of incremental adaptation with brief, discontinuous "reorientations," often triggered by executive succession or environmental shock. He is the constant co-author across the vault's whole organizational-punctuated-equilibrium research cluster: the 1985 *Research in Organizational Behavior* chapter with Romanelli that first names convergence and reorientation, the 1986 *California Management Review* article with Newman and Romanelli that carries the "3x more likely" frame-breaking-change figure, the 1992 *Organization Science* paper with Virany and Romanelli, and the 1994 *Academy of Management Journal* empirical test with Romanelli (author order reversed).
