Printable kit and facilitator guide for an in-person workshop

Then they stand in one spot for 15 minutes where the work is done, write what they see, ask one person one open question, and compare the desk sheet with the floor sheet. The kit has an 8-page facilitator guide, four sheets and filled-in examples from an invoice desk and a packing bench.
