Sample Chest

The Harbour Inn.

Project Overview

We are a 12-room boutique hotel. Our current system for tracking room cleaning and availability relies on staff radio communication and whiteboards, leading to guests waiting longer than necessary for their rooms.

Goal

Our overall goal is instant visibility. We need housekeeping staff to use a simple mobile interface to update a room's status immediately upon cleaning completion. This status change must instantly update the front desk view and, more importantly, a public-facing display showing current estimated check-in times. The system must prevent double-booking or assigning an "occupied" room.

Topics & Scope

Room Status Management

  • The system needs a Staff-only Login for housekeeping and reception.
  • Housekeeping staff need a simple mobile web interface to update a room's status: Occupied, Dirty, Cleaning in Progress, Ready/Available.
  • Reception staff need an interface to quickly mark a room as Occupied (upon check-in) and Dirty (upon check-out).
  • The database must securely associate the Room ID with its current status and cleaning history.

Real-Time Data Flow

  • The system must ensure staff and public displays update instantly when a status changes.
  • The system needs to calculate the "Next Available Room Time" based on scheduled check-outs and typical cleaning duration (e.g., Check-out at 11 AM + 1 hour cleaning = Ready at 12 PM).
  • The system must generate a critical alert if reception attempts to mark a "Dirty" room as "Ready" without housekeeping confirming "Ready."

Public/Private Display

  • Private Display (Reception): A detailed dashboard showing all 12 rooms, their color-coded status, and the assigned cleaner's name (if any).
  • Public Display (Lobby): A large-font web view (full-screen display) showing the total number of Ready/Available Rooms and the Next Guaranteed Check-in Time for a walk-in.
  • The system needs to automatically reset the room status to Dirty based on a pre-set check-out schedule (if available, otherwise rely on reception input).
