An inductive study of improvisation in new product development activities i
n two firms uncovered a variety of improvisational forms and the factors th
at shaped them. Embedded in the observations were two important linkages be
tween organizational improvisation and learning. First, site observations l
ed us to refine prior definitions of improvisation and view it as a distinc
t type of real-time, short-term learning. Second, observation reveal,ed lin
ks between improvisation and long-term organizational learning. Improvisati
on interfered with some learning processes; it also sometimes played a role
in long-term trial-and-error learning, and the firms displayed improvisati
onal competencies. Our findings extend prior research on organizational imp
rovisation and learning and provide a lens for research on entrepreneurship
, technological innovation, and the fusion of unplanned change and order.
