Quote by Kaoru Ishikawa
When you see data, doubt [them]! When you see measurements, doubt them!
Comment
quoted in Gemba Kazien by Masaaki Imai. His text after the quote: "He knew that many data are collected in the company to please the boss and that measurements are often made or recorded incorrectly by devices. At best, measurements are only secondary information that does not always reflect the actual conditions."
