Business Process Modelling (BPM) is a method of visualizing, analyzing, and improving business processes. It is a systematic approach to understanding and improving the flow of work within an organization. BPM involves the use of graphical models to represent business processes, such as flowcharts, data flow diagrams, and process maps. These models can be used to identify inefficiencies, identify areas for improvement, and develop new processes that are more efficient and effective. BPM is a powerful tool for understanding and improving the way an organization operates, and can be used to improve customer service, reduce costs, and increase efficiency. By using BPM, organizations can gain a better understanding of their processes and how they can be improved, and can make better decisions about how to use their resources.
