Bag-dispenser business cases rest on a single 2019 count

School of Continuous Improvement researchers re-run every dog-waste dispenser appraisal in one shire's files and find the paperwork costs more than the asset it argues for.

Sixty-three appraisals lodged under one shire's capital-works threshold share an uptake figure nobody has measured since

A shire spends more preparing the case for a dog-waste bag dispenser than it spends on the dispenser. One Count, Sixty-Three Appraisals, released today by the School of Continuous Improvement, re-runs seven years of those cases in a single economic model and reports what each of them actually turns on.

An appraisal is a way of taking trouble over a decision, and the threshold that requires one is doing something worth doing. What we would say, gently, is that the trouble collects around the parts of a model that are easiest to be careful about.

The team obtained the shire’s appraisal files, officer timesheets and dispenser servicing records in full, harmonised sixty-three separate cases into one twenty-year framework, and varied each parameter across the range a reasonable officer might have chosen. Most of the framework holds steady. One figure does not: the number of bags taken from a dispenser each week, counted over a fortnight at a single park in 2019 and carried forward, unrevisited, into sixty-one of the sixty-three files since.

The School describes the study as characteristic of an agenda it has been building for some time, tracing how a value enters an institutional model and what has to happen before it is ever asked to justify itself again. “The questions this raises about the difference between an estimate and an inheritance are ones we are glad to have on the table,” said Dr Renke Sabel, Senior Lecturer and Convenor of the Indicator Commons.
