The primary objective of this study was to review the extent of application of Strategic Management Accounting Practices (SMAP) by local Nigerian manufacturing enterprises in the making of effective decisions by business managers and accountants. Using a sample of ten manufacturing enterprises, fifty professional accountants and business managers working in the organizations were used in this study. In addition, questionnaires were used for gathering primary data. The Pearson Product Moment Correlation Coefficient and multiple regression analysis were adopted as the main statistical tools for this analysis. The first hypothesis shows a ranking of -0.58 which is less than 0.5 level of confidence. On the other hand, the second hypothesis shows that the sampled enterprises were hindered by inherent barriers in utilizing the benefits of SMAP resulting in the p value of 0.061 which is greater than 0.05. The results of this study indicated significant disapproval of SMAP among professionals working in indigenous manufacturing enterprises. The findings of the study may have implications on the management staff and accountant of the enterprise. Thus, this is because they revealed the below average knowledge of the workings of SMAP. As a result of this research, one is able to conclude on the need for managers to employ SMAP to enable them identify, accumulate, and manage the costs of their activities to ensure accuracy in their decisions making.
