This study investigates the impact of human resource (HR) system irregularities on the effectiveness of job scope allocation in small organizations, focusing specifically on performance management and talent acquisition. Using a qualitative approach, data were collected from a small organization providing adolescent mental health services. The findings reveal that role ambiguity, uneven workload distribution, lack of structured feedback, and undefined recruitment processes are key challenges affecting job scope effectiveness. The study underscores the importance of implementing structured HR practices to improve operational efficiency and employee satisfaction in small organizations. These improvements can enhance short-term performance and support long-term sustainability and growth.
