Robotic Process Automation (RPA) is software-based robotics which automates and offloads unnecessary processes performed by human workers. RPA was introduced by Hospital X primarily to support the operations team in making informed decisions about procurement as well as to notify vendors to bill for the consumed items. Before the implementation, the process was straightforward but tedious. After implementation, the process was considerably shortened. Instead of manually tracking and informing individual vendors, staff could simply submit a report to the RPA bot. However, inefficiencies remained in the procurement process. In this paper, we identify the operational inefficiencies that arise from RPA implementation using lean six sigma methodology. We map the current and to-be process and brainstormed for improvements. Finally, we compare the advantages and disadvantages of manual processes versus RPA to determine which one is more superior and analyzed the time savings from implementing RPA. RPA essentially automates some of the most mundane and repetitive computer-based tasks and processes in the workplace. It promises to boost efficiency by taking over tasks that were previously handled by humans. This paper contributes to the extant literature on RPA implementation and how lean six sigma and DMAIC methodology helped Hospital X to transition from manual to automated process and improve its procurement process.
