In this study, the effect of human resource strategy on business performance is investigated. The study uses a mixed-methods approach and includes interviews with 20 HR managers and a survey of 200 employees from diverse private sector businesses. The results point to a strong positive influence of human resource strategy on organisational performance, including financial performance, worker productivity, and client satisfaction. According to the report, an efficient human resource strategy that incorporates recruitment, training and development, pay and benefits, and employee engagement can boost employee commitment and happiness, which in turn improves organisational performance. Budgetary restrictions, a lack of support from top management, and reluctance to change are just a few of the difficulties that businesses have when implementing human resource initiatives. The study's recommendations for firms include developing and implementing successful human resource strategies that are in line with their corporate objectives and goals, as well as regularly assessing how well these strategies are working.
