The regression is based on the organization's performance and procurement planning process as predictors. The findings demonstrate a positive correlation with R = 0.684 and R2 = 0.573, meaning that changes in each of the predictor categories could account for 57.3% of the variance in the organization’s performance, the variances of the elements not included in this analysis account for the remaining 42.7%.
