Marketing strategists who operate in turbulent markets face a competitive l
andscape marked by volatility and evolving market structures. As customer r
equirements change, an organization that stays in alignment with its market
s will form new business units or alter the market charters of existing bus
iness units. In a longitudinal study, the authors traced the structural rea
lignments that accompanied a Fortune-500 firm's entry into the Internet mar
ket. As the charter moved from a freshly created unit to an established bus
iness unit, the authors found support for the prediction that the former or
ganizational structure will continue to shape the identity, beliefs, and so
cial ties of managers. The study highlights the structural, social, and cog
nitive factors that must be managed as corporate decision makers search for
the best strategy-structure fit for an emerging market opportunity.
