Abstract This study employed an integrative approach to investigate the influence
of external business environment, strategy formulation, viability of marketing
strategy, and strategy implementation upon firm performance. The findings show
that while technological change and market competition negatively influence
the credibility of the strategy, market attractiveness has a positive influence
upon the viability of strategy employed. Moreover, market competition has a
positive influence upon the involvement of marketing managers in terms of
strategy making and that the presence of an innovative culture is strongly
required in executing a strategic marketing plan. In addition, the study shows
that the involvement of marketing managers in strategy making, which is strongly
supported by an innovative culture, generates their commitment to the strategy,
which positively influences strategy viability.
