SPC Chart Reader
Read control charts and tell a real special-cause signal from ordinary random variation, across five scenarios.
Manufacturing QC & Six Sigma Simulator
Learn practical manufacturing quality control by doing it. Read control charts and tell a real signal from ordinary noise, trace a defect back to its true root cause, weigh preventive maintenance against breakdown risk, and compute Six Sigma defect rates.
Small business owners running their own production or service quality checks, and new graduates entering manufacturing, quality, or operations roles who want hands-on reps before the stakes are real.
Read control charts and tell a real special-cause signal from ordinary random variation, across five scenarios.
Categorize a real root cause into the correct Ishikawa category — Man, Machine, Method, Material, or Measurement.
Weigh preventive maintenance cost against breakdown risk to pick the right strategy for each asset.
Compute yield percentage and DPMO correctly — the numbers behind a Six Sigma quality program.
40 quiz questions across QC fundamentals, SPC, root cause analysis, and maintenance/Six Sigma math.
Earn SPC Analyst, Root Cause Investigator, Reliability Engineer, and Six Sigma Analyst badges, then unlock a certificate at 100%.
Completely self-contained sandbox — no internet required when run locally.
Educational simulation only — all production lines, defects, and equipment are fictional and simulated locally. No real manufacturing data is ever used.
Every session pairs with a quick 15–20 min real-world task that turns the simulator into a habit.
Think of a repeated problem you've noticed at work or home, and sort its likely cause into a fishbone category: people, equipment, process, materials, or measurement.
