Process Control and Quality Assurance in Production Training Course

Course overview

A production line rarely fails all at once. It drifts: a bearing warms, a batch of raw material shifts a few microns, an operator changes on the night shift, and the output slowly walks toward the edge of tolerance while every single part still passes the go/no-go check. This course is about catching that drift while the line is still running, using control charts and control plans to separate the normal noise of a stable process from a real signal that something has changed.

The focus is ongoing, in-line control rather than a one-time fix. You work with X-bar and R charts for measured dimensions, p and c charts for defectives and defect counts, in-process inspection points, measurement system analysis, and the corrective and preventive action loop that closes out a non-conformance. Throughout, the aim is a process that stays centered and predictable so first-pass yield holds steady from shift to shift.

Why this matters

Final inspection alone tells you which parts to scrap after you have already paid to make them. Control at the source tells you the process is about to make bad parts before it does, which is why in-process control and a documented control plan sit at the heart of any serious quality management system and of ISO 9001 in a manufacturing setting. The difference between control limits, which describe what the process actually does, and specification limits, which describe what the customer will accept, is the single idea most production teams get wrong, and getting it right changes how a line is run.

There is also a hard cost argument. A process that is capable but not monitored will eventually drift out; a process that is monitored but not capable will keep tripping alarms nobody can act on. Sustained production quality comes from watching capability over time, keeping measurement error small enough to trust the readings, and feeding every non-conformance back through CAPA so the same defect does not return next month. That combination is what protects first-pass yield and keeps scrap and rework off the cost sheet.

What you will be able to do afterwards

By the end of the course, participants will be able to:

• Select control charts and set control limits from process data.
• Interpret X-bar and R chart signals to decide when to act.
• Build control plans linking characteristics to reaction rules.
• Assess gauge reliability using measurement system analysis.
• Apply corrective and preventive action to eliminate root causes.
• Track first-pass yield and process capability trends over time.

Unit 2: Statistical Process Control (SPC)

• X-bar and R charts for continuous measurements.
• p charts and c charts for attribute data.
• Western Electric run rules for shifts and trends.
• Process capability monitoring with Cp and Cpk.

Unit 3: Quality Management Systems (QMS)

• ISO 9001 requirements on the shop floor.
• Control plan linking characteristics to reaction rules.
• Document and record control for traceability.
• Internal review of in-process controls.

Unit 4: Continuous Improvement in Production

• Corrective and preventive action for root-cause closure.
• Five whys and cause-and-effect diagrams for root cause.
• Control-chart history vs ordinary variation.
• Updated control plan and limits after process change.

Unit 5: Advanced Tools for Quality Assurance

• Measurement system analysis and gauge R&R.
• Failure mode and effects analysis for risk ranking.
• Acceptance sampling plans and AQL.
• Design of experiments for process centering.

Unit 6: Monitoring and Performance Measurement

• First-pass yield as a control indicator.
• Capability indices tracked over time.
• Non-conformance and defect-per-unit rate trends.
• Chart signals into clear reaction rules.

Unit 7: Future Trends in Process Control and QA

• Automated data capture for real-time control charts.
• Machine-assisted pattern detection with run rules.
• In-process control data linked across stations.
• Human decision-making in automated monitoring.

How the course is delivered

Each unit proceeds through review of completed inspection records and control plans, illustrative comparison of conforming and non-conforming production runs, and group interpretation of sample SPC output. Because it works from records and worked examples, the course sits alongside broader work on Quality Assurance in Manufacturing and Production without asking participants to operate any live line.

Who should attend

Those who benefit most are production and quality-control engineers, line supervisors, QA technicians, and manufacturing team leaders responsible for keeping output in specification. It suits anyone who already reads inspection data and wants to move from sorting good parts from bad to controlling the process that makes them.

About EuroQuest International Training

EuroQuest International Training began operating in 2015, with its administrative base in Bratislava, Slovakia. It offers 1,000-plus separate courses and has by now trained more than 15,000 people across industry worldwide. Sessions are held at its sites in Istanbul, Dubai, Vienna, Barcelona, and Geneva, so delegates can decide where and when they attend.

Frequently asked questions

Do participants get a completion certificate?

Participants do: everyone who finishes receives the EuroQuest International Training Certificate of Completion, It documents the learning undertaken and does not, by itself, certify a factory's quality management system to any standard. The course is educational and does not certify a quality management system or replace a formal conformity assessment.

Do I need a statistics background to follow the SPC material?

No. The charts are taught from the shop-floor logic first, and the small amount of arithmetic behind control limits is built up step by step from real inspection data, so anyone comfortable with basic measurements can keep up.

Does this cover Six Sigma project work?

Only where it touches day-to-day control. The emphasis is on keeping a running line in specification through SPC, control plans, and CAPA, not on running a separate improvement project or a third-party assessment of a plant.
