Production monitoring in Excel — free OEE, takt & Pareto; Pro adds logs, downtime analysis
Lean Operations Monitor helps manufacturing and continuous-improvement teams record production activity, capture planned and unplanned downtime, and turn operational data into practical performance insights — directly inside Excel.
Free tools (no account required)
- OEE Calculator — calculate Availability, Performance, Quality and Overall Equipment Effectiveness.
- Takt Time — compare production pace with customer demand and required output.
- Pareto Analysis — identify the vital few causes behind defects and operational losses.
Lean Ops Pro (optional subscription)
Pro adds a structured, workbook-based production monitoring system for plants, work centers and machines:
- Production Logs — record production activity and output by shift, machine, product and work center.
- Downtime Logs — capture planned and unplanned stops with structured loss categories.
- Reference Data — maintain work centers, machines, products, production rates and operators.
- Shift & Plant Setup — configure shifts, calendars, planned maintenance and operational exclusions.
- Loss Analysis — understand where production time and capacity are being lost.
- OEE Analytics — analyze equipment effectiveness from production and downtime records.
- MTTR & MTBF — monitor equipment reliability and maintenance performance.
- Operational Analytics — review production and downtime across machines, products, shifts and time periods.
The system is designed for manufacturing teams that want practical production monitoring in Excel without moving immediately to a dedicated MES.
