Stonehaven Transit identifies that 80% of light rail delays are due to 'Sensor Misalignment.' A control chart of the alignment process shows that while all measurements are within the ± 3σ control limits, the last seven points have all been above the mean.

What does this 'Rule of Seven' tell the project manager?

  1. The project manager must immediately halt all rail operations.
  2. The specification limits are too tight for this process.
  3. The process is in control because no points are outside the limits.
  4. The process is out of statistical control due to an assignable cause.
