The study considered the dynamics of environmental factors and the extent to which they moderate the influence strategic planning process formality has on performance. Approach to the study was descriptive, ex-post facto survey. A multiple constituency approach was used for performance measurement. Environmental characteristics incorporated a five-item environmental turbulence scale. Relationships between the variables (SPPF, DYNA, PERF) were analyzed with bivariate correlation, binary logistic regression test, and linear regression. Higher degrees of strategic planning process formality enhanced performance in environments where demand and customer tastes could fairly and easily be forecasted. Increased adherence to established standards (higher degrees of strategic planning process formality) is recommended for achieving desired outcomes.
