Still Green After You've Paid

A Season Embedded with a Petrol Station Forecourt as Staff Stop Trusting the Bay Sign

A research poster from the School of Continuous Improvement embeds with the forecourt staff of a suburban petrol station for a nine-week case study, finding the site's bay-availability sign's green read holds steady across the season while staff's willingness to act on it alone falls from 92% to 29%, with no change to the sign's software or refresh cadence.
