The dawn market perch, service by service

Perch Listing Desk

The Perch Listing Desk is the first workstation of the trading day. Before the gates open, stall holders and floor supervisors enter produce lines, quantities, prices and stall identities into one controlled register. We design this desk around the reality of a cold, busy entrance: large fields, short labels, forgiving validation and a visible confirmation for every committed line.

The build includes a duplicate entry guard, a time stamped edit history and a reconciliation view that compares the morning register against the previous close. When a stall changes hands overnight, the desk flags the mismatch before it becomes a queue problem. Handover notes are generated automatically so the night crew leaves facts behind rather than verbal assumptions.

Carol Queue Rounds

Carol Queue Rounds turn a crowded aisle into a readable line. We define timed call points along each branch, place simple visual cues that traders can follow without instruction, and give supervisors a short record of every round. The aim is not to police the queue but to make its rhythm obvious to everyone standing in it.

Each round carries a start mark, a set of zone observations and a close mark. If a zone stalls for longer than its band allows, the round raises a visible exception on the supervisor terminal rather than waiting for someone to notice. Over several weeks the round data becomes the raw material for the Plume Band Weeks review, which is why the two services are designed to share one register.

Plume Band Weeks

A Plume Band Week is a seven-day review cycle. At the end of each week we examine the band of indicators that describe how the market actually behaved: arrival spread across branches, queue duration by zone, stall turnover and the number of exceptions raised at the close. The analysis is compiled into a short written band report that reads as plainly as a weather note.

Each report names what moved outside its normal band, proposes one change for the following week and records what was tried last week. We deliberately keep the report short enough to be read in a single sitting at the market office, because a document that nobody reads cannot improve a morning. Reports are archived so that a season can be compared without opening a spreadsheet.

Dawn Drop Days

A Dawn Drop Day is a live rehearsal of the entire system on a real trading morning, with engineers present on the floor. It is scheduled deliberately before the busiest dates of the season, when a festival or a harvest peak will push arrivals and queues beyond their usual range.

On the day we run the full sequence: listing desk, queue rounds, band observation, branch walk and roost check. Engineers watch the integrations in place rather than remotely, note every hesitation and publish a short debrief before the afternoon. The debrief lists what held, what wobbled and what will be changed before the next rehearsal. No trading time is lost, because the rehearsal uses the ordinary morning rather than a simulated one.

Branch Walk Sessions

Branch Walk Sessions pair the physical market with its digital twin. A supervisor walks a named branch route, checking that stalls, signage, pricing boards and queue cues match what the register says should be there. Each session is short, repeated on a fixed cadence and deliberately unglamorous, because its value comes from repetition rather than from ceremony.

Discrepancies are recorded on the spot with a single observation entry, which then flows into the evening close. We build the walk route into the interface so that the same zones appear in the same order each time, and we keep the entry form small enough to use with gloves. Over a season, the walk record reveals drift before it turns into a dispute.

Roost Check Evenings

Every trading day ends with a Roost Check Evening. The close reviews outstanding entries, records exceptions, confirms the reconciliation between the morning register and the final floor state, and prepares the opening page for the next morning. We design the close so that it fits inside the final half hour of the shift without rushing the crew.

The evening check produces a single signed summary that the night crew inherits, and it flags anything that needs a decision before the gates open again. When something cannot be resolved, the check captures the facts, the person responsible and the time, so that the next shift starts with a question rather than with a hunt. A clean roost check is the quietest measure of a well designed morning.
