Abstract
Value Stream Mapping (VSM) is a tool used to analyze the workflow across all systems. This concept has been applied in the development of public health services. Objectives: To develop the sub-inventory management system of the pharmacy department for non-communicable diseases (NCDs) using Value Stream Mapping. Materials and methods: This action research collected data on the workflow of the NCD substock system and analyzed the processes using Value Stream Mapping to identify waste. The system was redesigned using the Eliminate, Combine, Rearrange, Simplify (ECRS) framework to reduce unnecessary steps and improve efficiency. After implementing the new system, key performance indicators were gathered to assess the effectiveness, and results were reviewed for further improvement as needed. Results: Analysis of the substock management process using Value Stream Mapping reduced the number of steps in managing NCD inventory from 8 to 6, leading to increased efficiency. The time spent by pharmacy technicians managing the NCD inventory decreased from 357 minutes to 175 minutes, representing a 50% reduction in work time. Conclusion: Value Stream Mapping is a tool that provides a comprehensive view of the entire system, helping to visualize workflow, work time, and identifying valuable, necessary, and wasteful steps. This leads to the development of the most efficient system possible.
