So there are several process mining tools available, and here you see nine most prominent commercial tools. These tools have certain things in common and can be viewed as a Swiss army knife with a few tools. And these commercial tools are actually well-tested, user friendly, and can handle large data files. So they have only a few tools, few features, but what they do, they do well. However, they have limited functionality, so they only support a couple of analysis features, and advanced features are often missing.
