Mahbub-ul- Alam 4 Abstract The purpose of this study was to investigate Fayol's principles, practices, uses, and application as an effective management tool in public administration; to determine the relationship between Fayol principles and effective management in public administration; to measure or assess the impact of Fayol principles on effective management in public administration; and to make policy recommendations. A quantitative research technique is utilized with a structured questionnaire survey instrument and scale variables to capture all of the study goals. In this study, person correlation using regression analysis is used to assess the research model and assumptions. Finally, factor analysis is used to discover key elements from the 14 Fayol's principles. Three elements are discovered, two of which have a substantial impact on efficient public administration management. Nine independent variables have a positive and substantial impact on good public administration management in the first regression model with 14 principles. Positive and significant (p.000) 22.1 percent and 20.9 percent of total variance explained on successful management in public administration are demonstrated to be code of conduct and harmonious connection. As a result, for successful management components in public administration, policymakers should think about those factors more accurately. In the future, qualitative research techniques may be used to broaden the sample scope.
