The premise of human resource management practices is that an organisation's most important resource is its people, and that its performance depends heavily on them. For human resource management to have a meaningful impact on organisational performance, an appropriate range of human resource policies and processes must be developed and effectively implemented. Strategic human resource management is an approach that defines how the organisation's goals are achieved by its employees through human resource policies and practices that are integrated with the human resource strategy. Strategic Human Resource Management's growing popularity is primarily due to its clear commitment to improving organisational performance. However, studies on the linkage between strategic human resource management practices and organisational performance that have been carried out in the African perspective, are very few especially in a public organisation. The purpose of this study was to examine the impact of strategic human resource management practices on organisational performance. The study was conducted at the National Assembly of Zambia which has its presence in all the one hundred and fifty-six (156) Constituencies through Parliamentary Constituency Offices. The study utilised quantitative research method. Data was collected from the study participants using a questionnaire. Collected data was analyzed using descriptive statistics and statistical inference (Pearson Correlation Coefficient and Multiple Regression Analysis). The Pearson Correlation Coefficient was used in order to find out the relationship between the variables and the Multiple Regression Analysis was used in order to find out the impact of independent variables on the dependent variable. The hypothesis test results revealed that there was a relationship between all human resource management practices
