You do not need to settle the debate about future employment to examine one current workflow. Choose a problem its owner recognizes, inspect the work behind it, and agree what a useful change would have to demonstrate.
We run this on ourselves. We have mapped our own delivery workflows into their tasks and found tasks no job description owned. After a customer reported slow lab access, we added a user-geography question and a provisioning-region review. We do it live with customers: upload a job description, watch it decompose into classified tasks, argue with the classification, and leave with a proposed preparation plan tied to the tasks that change. That argument, by the way, is the best meeting in the whole process. People defend their work task by task, and that is exactly the conversation that rarely happens when the discussion stays at job titles.
The classification conversation produces questions and a proposed plan. Building the change, preparing its users and checking its performance against agreed cases are further work. We scope that work around the enterprise’s systems and responsibilities.
