Thesis (Ph.D. (Commerce)) -- University of Limpopo, 2021 / This research aimed to develop a costing model for the African Complementary and Alternative Medicines (ACAM) health practitioners to improve their products and services’ decision-making process. This research aim drew support from fundamental objectives, which includes amongst others, the identification of the current product and service costing approaches used by the ACAM practitioners and how this supports their decision-making, the development, and adoption of a costing model for ACAM practitioners to capture products and services’ cost information for improved health care service delivery. Furthermore, it sought to understand the challenges faced by ACAM practitioners in adopting the proposed costing model. The research applied a qualitative action research method. Data collection was through interview method from twenty-six ACAM health practitioners in six ACAM health care facilities. Data were collected after two research cycles in the field study through action research procedures. The participants were drawn from five South African provinces. The main data was gathered through face-to-face semi-structured interviews, documentation, and direct observation to enhance the research validity and reliability. The data were analysed systematically using thematic analysis The findings reveal that the study succeeded in providing more accurate cost data for each product and assist in the planning, control and decision making for the ACAM practitioners. The research contributes academically and to practice by successfully narrowing the gap between ACAM researchers and cost accounting researchers by providing a practical costing model based on solid practical and academic foundation. The researcher recommends that the South African ACAM facilities need to adopt and implement the ACAM costing model because it will provide them with more accurate cost data for the provision of each service and products and help in making effective and reliable decisions.
