Before you start: Distinguish process behaviour from specification requirements.
Try it
Every observation is within the specification limits. Does that prove the process is statistically stable?
Your reasoning, assumptions and units:
Apply it to your work
Describe a comparable situation. What evidence would you need before using this reasoning to make a decision?
Your example and next check:
Answer and reasoning
No. Specifications describe requirements; control limits describe expected process variation. Examine the time-ordered observations for signals and investigate their causes using appropriate process evidence.
