Does Yamazo Studio calculate OEE directly?

Yamazo Studio is a video-based time study tool, not a real-time OEE monitoring system. However, its analysis directly supports OEE improvement by identifying the root causes of availability, performance, and quality losses through detailed video analysis.

What is considered world-class OEE?

World-class OEE is generally considered to be 85% or higher (90% Availability x 95% Performance x 99.9% Quality). Most manufacturers operate between 60-75% OEE, meaning significant improvement opportunity exists.

OEE (Overall Equipment Effectiveness) | Manufacturing KPI Guide

OEE (Overall Equipment Effectiveness) is a manufacturing KPI that measures how effectively equipment is utilized. It combines three factors: Availability (actual run time vs. planned production time), Performance (actual throughput vs. maximum throughput), and Quality (good units vs. total units). OEE = Availability x Performance x Quality, expressed as a percentage. World-class OEE is typically 85% or higher.

How to Create

While Yamazo Studio focuses on time study and work analysis rather than real-time OEE monitoring, its video-based analysis directly feeds OEE improvement initiatives. Use Yamazo to identify the root causes of availability losses (changeover time via SMED), performance losses (cycle time variation via time study), and quality losses (process deviations via standard work analysis).

Example

A packaging line had 62% OEE. Video analysis with Yamazo Studio revealed that 23% of downtime came from changeover (addressed via SMED) and 15% from operator wait time due to poor line balance (addressed via yamazumi-based rebalancing). After improvements, OEE rose to 78%.
