Small business development is analysed in terms of transition phases t
hat link phases of comparative stability. Enterprises founded as owner
-operated businesses may evolve into a functionally organized entity;
if so, they move through two distinct transition phases. These transit
ional phases lie between the owner-operated and an owner-managed organ
ization, and between the owner-managed and a more complex organization
guided by functional managers. Each of the five phases is marked by p
articular characteristics, and calls for a phase-specific blend of ent
repreneurial and management activities. The framework recognizes that
not all small enterprises pass through all five phases; there are firm
s that start in a more evolved phase, and there are many that remain w
ithin a particular phase, either by design or by virtue of barriers to
further development.
