Why This Matters
OEE combines Availability, Performance, and Quality into a single measure. Traditional OEE reporting is reactive and lagging—by the time insights are available, the opportunity to act has passed.
Litmus Enables
  • Real-time OEE calculation by line/asset/shift with standardized loss tree
  • Automated downtime and microstop capture with reason-code assistance
  • Performance loss detection (speed loss, starvation/blockage) with operational context
  • Quality loss correlation to events and conditions
  • Close the loop: turn predictions into real-time edge actions
Discovery Questions
Use these to guide client conversations
  • Current OEE: __% with A/P/Q breakdown; what are the biggest loss buckets?
  • How does actual speed compare to ideal? What is the cycle time distribution?
  • Quality losses: FPY __%, scrap __%, PPM; what is the warranty cost per year?
  • How long does it take to detect and respond to a loss event?
  • What is the current process for capturing reason codes and loss classification?
