Short pauses paired with caffeine can restore attention and reduce decision fatigue. Measure error rates, rework, or helpdesk escalations around peak slump hours before and after implementation. Encourage intentional breaks, not longer ones, and monitor whether interruptions decrease as people schedule quick refuels instead of ad hoc wanderings.
Spontaneous chats at the machine often bridge silos. Track cross-functional tickets solved faster, introductions made, and follow-up meetings scheduled after informal encounters. Qualitative notes from managers add color, but aim for tangible indicators like shortened approval cycles, shared documents created, or prototypes emerging from conversations sparked over cappuccinos.
