The exercise works best when participants receive clear instructions before beginning.

  • Roles: Instruct teams to decide on a tester, timekeeper, and accuracy inspector.
  • Starting Set Up: Each PDSA cycle begins with all of the parts are inside the storage compartment of the Mr. Potato Head body and the compartment door is closed. If the hat or legs do not fit, they may be placed beside the body.
  • Measurement Definitions:
    • Time: Clock starts when the tester touches Mr. Potato Head. Clock stops when tester stops touching Mr. Potato Head AND says, “Time!”
    • Accuracy: Inspectors can assess an accuracy score from one to three. A score of one means one or more of the required pieces are not on Mr. Potato Head. A score of two means all of the pieces are on Mr. Potato Head, but one or more pieces is grossly out of place. A score of three means all of the pieces are on Mr. Potato Head and positioned correctly.
  • Documentation: Each participant is instructed to track their team’s data on their own handouts. This includes the four phases of each PDSA on the PDSA tracker form and plotting the time and accuracy data on the run charts.
  • Pacing: For each cycle, participants will make a “plan” to test a change idea and capture the time and accuracy scores predicted for the test. Tables may “do” their test and complete the “study” and “act” phases including documentation. Teams will wait for the facilitator’s instructions before initiating another test.
  • Optional: Have each team write their time and accuracy scores on a slip of paper at the end of each test and submit to the facilitator. Enter the team data into a spreadsheet to track small multiples of all of the teams’ data for discussion at the end.
