Robotic Process Automation (RPA) comprises a set of emanating technologies that promise to automate business processes. This is achieved by simulating the way a human performs the target process. Although the time and cost savings advantages of RPA and other related performance metrics have been shown in various contexts, we found no literature review of the quantitative results. This requires an in-depth study to illustrate the quantitative benefits of RPA across multiple industry sectors. This paper presents a structured literature review based on various industry sectors. The aim was to analyze the quantitative benefits of Robotic Process Automation (RPA). We are presenting the potentials of RPA in each industry using case studies and prober RPA processes in each sector. The study concludes that although there are tremendous quantitative benefits of implementing RPA, only a few organizations in each sector reported their quantitative results.
