Lean Operations Monitor

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.

Works inside Excel

Your operational workbook remains the working data source. The add-in provides structured tools for setup, logging and analysis. Workbook analysis runs locally in Excel.

Free features do not require an account. Pro requires sign-in (Microsoft, Google, or email) and an active subscription processed by Paddle (Merchant of Record). Cancel anytime via Manage billing in the add-in.
