IASSC Certified Lean Six Sigma Yellow Belt (ICYB) — Question 8
The length of wooden beams being sawed is measured by a line operator. Which is least likely to be influenced by the instrument?
Answer options
- A. Calibration of the instrument
- B. Actual temperature of the liquid
- C. Recording the measurement
- D. Reading of the instrument
Correct answer: C
Explanation
The recording of the measurement is a process that occurs after the reading has been taken, and is therefore less likely to be influenced by the instrument itself. In contrast, the calibration, actual temperature of the liquid, and the reading of the instrument are all directly affected by the measurement process and the instrument's performance.
