A School of Continuous Improvement research poster sorts the status lines on a courier's tracking page by the evidence behind each, and sets out which kinds a household notice board and a parcel-pickup counter may act on.
A taxonomy called TRACE tells a front door and a pickup counter which status lines may be acted upon.
A parcel’s tracking page says a good deal before it says anything about the parcel. A research poster from the School of Continuous Improvement, published today, introduces TRACE, a taxonomy that sorts each line a courier displays into one of four kinds according to what the sender can be said to know when the line appears.
Associate Professor Casimir Beng, Lead of the Adaptive Metrics Lab, led the work with Dr Dagny Okafor, Lecturer and Convenor of Evaluation of Evaluation, and Dr Bram Ntuli, Lecturer and Convenor of Improvement Grand Rounds. The team followed 214 parcels across four carrier classes, set each page refresh against a closed list of kinds, and worked alongside thirty-eight households and one strip-mall pickup counter to see what changed when the kinds, rather than the wording, were allowed to decide what happened next.
The page had been telling us the truth all along, in four different tenses. We simply had not yet agreed on the grammar.

The University is pleased to see a quiet corner of everyday life receive the attention of a settled vocabulary. The poster sets out how the notice board by the front door and the shelving at the counter are to be organised around the kinds, and the School regards the arrangement as a sensible, well-scaled step in the care of the everyday signals people rely upon. Dr Okafor said that the households “were generous with their doorsteps, and patient with us while we learned to tell a promise from a parcel.”
