I'm always surprised at the lack of interest in modelling business processes here on HN.<p>This blog post from Uber is a case in point: 19 hours after posting, there are still zero comments.<p>When I started my career 25 years ago, I was a junior management consultant and often had to model the impact of the major corporate changes we proposed to our clients. One example I remember well was figuring out how a bunch of reengineering initiatives would change the work done across a network of 1000 retail bank branches. I built an Excel model that figured out branch-level workloads, proposed changes to the number and function of branches, and then presented the personnel, real estate and operational cost impact...<p>I am sometimes curious how these types of models would be built today. My natural assumption (as a data scientist) would be use Python in a Jupyter notebook to do it all. However, my attempts at web searches for examples of business modelling techniques never return anything relevant.<p>Maybe someone reading this (from BCG/McKinsey/Pwc/etc?) can explain how they model the impacts of large scale business change?
