Publication number: 20240144144Abstract: Process transformation can include mapping, by a first machine learning model, predetermined key performance indicators (KPIs) to a discovered process model. For each of the KPIs, a KPI gap and a KPI impact score can be determined. For each of the KPIs, a KPI-level enhancement potential value based on the KPI gap and KPI impact score of each KPI can be determined. Based on the KPI-level enhancement potential value of each of the KPIs, a process value debt (PVD) can be generated. Responsive to the PVD exceeding a predetermined threshold, a process transformation recommendation generated by a second machine learning model can be outputted to identify at least one modification to the process that is likely to reduce the PVD.Type: ApplicationFiled: October 27, 2022Publication date: May 2, 2024Inventors: Radha Mohan De, Soumya Nandy, Amitabha Mitra
