Quality & operations
Practical calculators and quick checks for quality, manufacturing and process work.
Quality & operations
Free quality and operations calculators for Cp/Cpk, Pp/Ppk, OEE, takt time, PPM/DPMO, yield, FMEA RPN and risk matrices.
Cp & Cpk Calculator
Calculate process capability in seconds and see which specification side is limiting your Cpk.
FMEA RPN Calculator
Calculate RPN from Severity, Occurrence and Detection without turning the number into a false universal acceptance limit.
ISO 9001 Readiness Quick Check
A guided, browser-only assessment that turns 18 practical questions into a readiness overview, focus areas and three next actions.
OEE Calculator
Break OEE into Availability, Performance and Quality so you can see which loss is pulling the result down.
Pp & Ppk Calculator
Check long-term process performance against specification limits and see which side is limiting Ppk.
PPM & DPMO Calculator
Separate defective units from individual defects and convert both into comparable per-million quality metrics.
5×5 Risk Matrix
Turn severity and likelihood into a simple 5×5 risk score for quick prioritisation and discussion.
Takt Time Calculator
Turn available production time and demand into the required production rhythm — seconds per unit and units per hour.
Yield & FPY Calculator
See how much output passes first time and how much of the final yield is being recovered through rework or sorting.
