A School of Continuous Improvement research poster names five levels of cleaning tick-sheet practice at park toilet blocks, and records the shire's decision to visit blocks at the fourth level and above once a fortnight.
A five-level model called LATCH scores 46 tick-sheets, and a shire's depot lets the fourth level set the round.
From the next cleaning round, a regional shire will read the clipboard on the door of each park toilet block before it decides when to come back. A research poster from the School of Continuous Improvement, published today, introduces LATCH, a five-level hierarchy for the way a block’s tick-sheet is filled in, and sets out how the shire’s works supervisor came to rely on it.
The poster is led by Dr Joost Nwosu, Postdoctoral Fellow, with Dr Solveig Adeyemi, Lecturer, and Dr Ingeborg Nwachukwu, Lecturer and Convenor of Capability Sprints. The team worked with the supervisor across forty-six blocks in eleven parks, scoring each sheet against named levels that run from a clipboard simply being present to a sheet that is countersigned and retained, and then following the shire’s depot through the adoption of the fourth level as the standing threshold for a fortnightly round.
Each level was a habit a supervisor already half had, and naming them gave the depot something it could point to from the road. We are grateful to the shire for letting the ladder be fixed to a door.

Dr Nwachukwu said the School was pleased that a model had travelled so far from the page: “A sheet is a small act of attention, and it is a pleasure to see the depot give that attention a rung of its own.”
The release marks a quiet step in the University’s work on how a record comes to stand in for a visit. The shire has lettered each block’s level on its door, and the School will return for a third audit cycle with a sixth level in mind.
