A School of Continuous Improvement poster codes 214 verge-mowing exemption applications into six categories and finds a shire compliance unit has adopted the coding as its own differentiated waiting-period schedule.
Six categories coded from 214 mowing-exemption applications now set how long each one waits
Two boxes on a shire’s exemption form — heritage garden, safety hazard — were meant to hold every reason a verge goes unmowed. A poster published today by the School of Continuous Improvement reports that applicants write in categories the form was never built for, and that the compliance unit issuing the form has started sorting its queue by them.
Dr Torun Ezeigwe, Senior Lecturer and Director of the Master of Applied Measurement, led the work with Dr Anouk Mensah and Dr Sten Okwuosa, Senior Research Fellow and Convenor of the Impact Pathway Atlas. Two coders read 214 free-text justifications lodged with a single shire compliance unit over two years and reached a six-category scheme by consensus, agreeing on the assignment often enough to call it reliable. The unit has since begun issuing a different processing wait for each category, even though the scheme was built to describe what applicants wrote, not to decide who waits.
A form has two boxes because two boxes were once enough. Ours found six, and the unit is already using them.

“This is exactly the kind of drift the Impact Pathway Atlas exists to catch,” said Dr Sten Okwuosa, “a scheme built to read the file ending up inside the decision it was only meant to describe.”
The release reflects the School’s growing comfort treating its own coding schemes as findings in their own right, worth publishing before anyone downstream mistakes them for policy.
