Pair & Group Discussion in QA Training
Process Control Basics
Table of Contents
Part 1: Scenario Analysis (The “Why” and “How”)
Instructions:
In your groups, review the following scenario and discuss the questions provided. Note your collective conclusions for a brief presentation to the class.
Scenario:
A UK-based food production facility is experiencing inconsistencies in the weight and temperature of “ready-meals.” Some batches are overfilled (wasting material), while others are under-temperature (failing safety standards). The facility must adhere to the Weights and Measures Act 1985 and UK Food Hygiene Regulations.
Discussion Points:
- Defining Control: How would you define “Process Control” in this specific kitchen environment? Is it about the final product or the steps taken during cooking?
- Identifying Techniques: Discuss which techniques would be most effective here.
- Examples to consider: Statistical Process Control (SPC) charts, automated sensors, or manual “check-and-record” logs.
- Regulatory Impact: How do UK regulations (like the Weights and Measures Act) dictate the “Control Limits” you set for the machinery?
Part 2: The Link to Consistency
Instructions:
Use your collective vocational experience (or placements) to complete the table below. Discuss how a failure in process leads to a failure in consistency.
| Process Variable | Control Method (Manual or Auto) | Impact of “Out of Control” Process |
| Example: Oven Temp | Thermocouple / Digital Readout | Uneven cooking; potential health risk. |
| Example: Cutting Tool Speed | CNC Programming / Operator Check | Rough surface finish; part rejected. |
| Your Choice: |
Part 3: Monitoring and Compliance (UK Standards)
Instructions:
Focus on the “Competency” aspect of monitoring. Discuss the following prompt:
“In a UK workplace, if a process monitor shows a ‘Trend’ moving toward a limit—but it hasn’t broken the limit yet—what is the competent action to take? Why is ‘Correction’ better than ‘Rejection’?”
Key UK Frameworks to Reference:
- BSI (British Standards Institution): Specifically how ISO 9001 principles regarding “Evidence-based decision making” apply to your monitoring logs.
- Health and Safety at Work Act 1974: Discuss how losing control of a process (e.g., pressure in a valve) transitions from a Quality issue to a Safety issue.
