Implementation pervades strategic performance. It is a critical link betwee
n the formulation of marketing strategies and the achievement of superior o
rganizational performance. Research conducted in this area generally has su
ffered from a lack of conceptual and empirical grounding. Furthermore, impl
ementation research often ignores the mid-level managers, who are intricate
ly involved in most implementation activities. The authors integrate a broa
d literature review and a grounded theory-building process to develop a mod
el of important factors that influence the implementation of marketing stra
tegies from a managerial perspective. They test this model in a study of mi
d-level marketing managers in two different organizations. The results prov
ide insights into the nature of implementation in marketing and suggest fut
ure research opportunities.
