Manufacturing Execution Systems Explained: From Planning to Delivery

A Manufacturing Execution System (MES) manages, monitors, and syncs work execution on the factory floor — from raw material to finished product. It tracks work-in-progress, machine performance, and labour to ensure the plan from your scheduling system is executed efficiently. Most importantly, an MES integrates your back office with the shop floor, connecting ERP systems with real-time production data for complete operational visibility. It reveals bottlenecks and process inefficiencies through continuous improvement, expanding capacity and reducing lead times.

Smart Shop Floor's operator interface is distraction-free and purpose-built. Digital job packets deliver work instructions, drawings, and material lists to tablets. Operators update job status, complete digital forms, and message supervisors directly. Automatic time tracking captures labour costs and downtime reasons without manual timesheets. Workers quick-log production events with minimal taps, building a clear picture of operational performance. The Andon light integration changes colour based on operator actions, making it immediately visible when assistance is needed.

Real-time production boards show work status across all machines and operators with colour-coded priority levels. All staff see shop floor operations and daily work plans without walking the floor, keeping everyone informed. Customisable displays show planned work by department, operator, or machine with scheduled run times. Updates throughout the day as staff report completed jobs, with automatic rescheduling of remaining work to accommodate last-minute changes.

Wireless sensors track machine run time via vibration monitoring without manual entry. They work with legacy and modern equipment alike. Optional equipment health alerts flag when servicing is needed, preventing unexpected breakdowns. The sensor data feeds directly into the scheduling algorithm, providing ground-truth information about machine availability and utilisation that no manual reporting system can match.
