School of Continuous Improvement researchers built a service that decides whose turn it is to buy the milk, ran it in 46 workplace kitchens, and report that buying outside the roster all but stopped while mornings without milk rose.
A fourteen-month deployment across 46 shared workplace kitchens, and the contribution ledger the Indicator Commons has adopted from it
The milk in a shared workplace kitchen has never been anybody’s job in particular. For fourteen months, researchers from the School of Continuous Improvement made it somebody’s job, and counted what changed.
Deploying a Milk-Rostering Service Across 46 Shared Workplace Kitchens, released today as a research poster, reports on the Shared Kitchen Rostering Service, which nominates the next purchaser, prompts them by message, and posts each rostered purchase to a per-person contribution ledger. Across the participating kitchens, buying outside the roster fell from a pooled 4.1 purchases per site-month to 0.3 and did not recover. Over the same period, mornings on which the fridge held no milk rose from 1.2 to 2.9.
Coordination is one of the oldest things an institution has to offer, and it is not always the thing a kitchen was short of. The School is glad to have a way of asking that question before it offers coordination again.

The deployment paired fortnightly on-site counts with till receipts and service telemetry across four site types, with the study’s outcome definition lodged before the first roster was issued. Postdoctoral Fellow Joost Nwosu said the ledger “gives the University a record where it previously had a habit”, and that the team is now looking at how far the same instrument travels into tea, coffee and biscuits.
The University regards the work as a demonstration of what its measurement capability can offer the ordinary machinery of shared working life. The ledger now stands as the Indicator Commons’ contribution record of record at participating sites.
