Establish Key performance indicators (KPI) for each job function and track it using BPM tools. Create an objective within the BPM system and analyze how many employees in a particular department for a specific role were able to accomplish it and if the majority of them are unable to do it then the problem is either with the training or business process.
If a few employees are struggling with it, you can push notifications within the application with guided workflows to ensure that they complete the process the way you intend. You can also measure other indicators too like average session time, task completion rate, and active state within the application.
