The Parking Lot tool, created by David P. Langford, is available as a laminated 32" x 24" poster. People can "park" notes suggesting positive comments, needs for improvement, general questions or insights for review at a later time. The Parking Lot poster is used as a tool to anonymously communicate feedback to teachers, administrators, facilitators, managers, teams or group leaders. It is also used when ideas, questions or comments emerge at times when they cannot be explored as it allows feedback to be collected and acted upon later. The Parking Lot is commonly used in steps 1, 2, 6 and 9 of the PDSA (Plan-Do-Study-Act process). It can also be used as a method to provide ongoing continual improvement feedback processes in classrooms, staff rooms, and building entrances.
