A sample answer to question 1

How do you map a current-state process, and which tools and notations do you use?

I never map from a desk. I start by agreeing scope with the process owner using a SIPOC, which shows suppliers, inputs, process, outputs and customers at a high level, so we know where the process starts and ends. Then I walk the process with the people who actually do it, watching real work rather than relying on procedures, and I record steps, handovers, systems used, wait times and rework loops. For the detailed map I use swimlane diagrams in Visio or Lucidchart, often in BPMN notation if the organisation uses it, and for short workshops I use sticky notes on a wall or Miro, which gets people talking. I then validate the draft with the team and a couple of different operators, because people frequently describe the ideal process rather than what happens. Finally I add data to the map, such as time per step and volumes, so we can find where the real delay and waste sit before designing improvements.

Common mistake to avoid: Mapping the documented process rather than the actual one; skipping validation with staff
