A booking must reserve more than a place on a screen
A booking design should account for every resource in its promise before optimising the path to confirmation.
We rehearsed sixty appointments that required a practitioner and an additional room or support resource. Nine looked available in the product without all the necessary resources being reserved. The calendar was not producing a random error. It represented the practitioner, which was the object we had originally asked it to represent. The product's confirmation then implied something larger:that the appointment could proceed within the provider's agreed administrative arrangements. The gap was between the model and the promise made through it.
