28 Quality Control Survey Questions for Accurate Feedback

Product Quality Inspection Survey (Internal Audits)

Why & When to Use

For those who live and breathe quality, the internal audit survey is like a trusty checklist. These surveys are built especially for QC inspectors on the factory floor, who want to catch non-conforming products before they slip through the cracks.

Deploy inspection surveys during in-process or final product inspections. Not only do you prevent the accidental shipping of lemons, but you also build a foundation for solid statistical process control (SPC).

With a quality inspection survey, you’ll always know if batches are up to spec (and up to snuff).

On top of that, you get to: * Lock down regulatory compliance * Collect hard data that pushes continuous improvement * Initiate corrective actions with zero fuss

Busy? This approach keeps your team focused on the numbers that matter, like defect rates and critical pass/fail criteria.

5 Sample Questions

1. Were all dimensional tolerances within the specified limits? (Yes/No)

2. How many visual defects were observed per 100 units?

3. Did packaging pass drop-test requirements? (Pass/Fail)

4. Rate the overall production batch quality from 1 (poor) to 5 (excellent).

5. List any corrective actions initiated during this inspection.

Remember, every “yes”—or “fail”—here helps you eliminate non-conforming products before they become very expensive mistakes.

Including at least one open‑ended question in quality control surveys significantly enhances engagement and yields richer insights than relying solely on closed-ended questions (source)

Employee Self-Inspection Checklist Survey

Why & When to Use

Feeling outnumbered by process problems? Grab the self-inspection checklist as your secret weapon. Handing accountability to your operators helps boost morale, reduce those annoying bottlenecks, and send quality issues packing.

This approach is perfect for lean or Six Sigma environments. It's fast, empowering, and requires zero paperwork headaches. Operators fill out these surveys at the end of each shift or before moving their work downstream.

Here's why this rocks: * You foster ownership of quality * Detect issues before they snowball * Build quality at every workstation, every shift

Plus, self-checklists turn each employee into a quality champion, all while freeing up your quality inspectors for the big-picture stuff.

5 Sample Questions

1. Did you verify torque values for all fasteners? (Yes/No)

2. Was the workstation cleaned and organized after the task? (Yes/No)

3. Rate your confidence that this unit meets quality standards (1-5).

4. Were any deviations from SOP detected? (Checkbox: None / Minor / Major)

5. Describe any tools or resources you lacked to complete the job to spec.

As a bonus, people secretly love getting to check off boxes—it makes them feel accomplished (and makes quality management way easier).

Supplier Quality Assurance (SQA) Survey

Why & When to Use

Ready to separate superstar suppliers from the duds? The Supplier Quality Assurance survey is built for you. You need these for both onboarding new suppliers and doing annual or quarterly check-ups on the familiar faces.

Here’s the scoop: SQA surveys keep your multi-tier supply chain in check. You stay on top of requirements for certifications like ISO 9001 or IATF 16949.

If your supplier is up to the challenge, fantastic. If not, you’ll know before you have a big problem on your hands.

With this survey, you’ll: * Measure supplier defect rates and timeliness * Confirm their quality management systems * Surface their commitment to continuous improvement

Plus, it doubles as documentation for your own audits—making you look sharp, organized, and always two steps ahead.

5 Sample Questions

1. What is your current defect rate (PPM) for delivered components?

2. Do you maintain a certified ISO 9001 or IATF 16949 QMS? (Yes/No)

3. How quickly can you implement corrective actions after a non-conformance report? (Days)

4. Rate your on-time delivery performance over the past 12 months (1-5).

5. Provide evidence of continuous improvement initiatives completed in the last year.

Choosing the right supplier often comes down to their answers on this list—and yes, a little playful pressure goes a long way!

A study of a steel pipe manufacturer in India found that supplier evaluation significantly improves process performance, with delivery reliability and relationship management being more influential than quality or cost. source

Post-Implementation Quality Audit Survey (Services & Projects)

Why & When to Use

Launching a killer software, completing a massive installation, or just finished a consulting gig? Don’t walk away yet. A post-implementation quality audit reveals if the delivered solution really matches what's on your contract (and your customer’s dream sheet).

Send these surveys right after the hand-off. You’ll measure if implementation quality matches expectations, surfaces any punch-list items, and captures lessons for next time.

This tool helps you: * Lock down contract compliance * Catch lingering quality problems before they turn to complaints * Fuel your team’s process for continuous learning

Here’s your chance to really check if work meets the highest standards—and show the customer you don’t just meet expectations, you beat them.

5 Sample Questions

1. Did the delivered solution meet all defined acceptance criteria? (Yes/No)

2. Rate the workmanship/professionalism observed during implementation (1-5).

3. Were project milestones achieved without quality-related delays? (Yes/No)

4. Identify any outstanding punch-list items affecting quality.

5. How confident are you that the solution will perform reliably for the next 12 months? (0-10)

Whether it’s a hospital wing or an app rollout, these survey questions help ensure your service or project quality truly delivers.

Return & Defect Analysis Survey

Why & When to Use

Nothing stings like a product comeback. But every return has a story—and your defect analysis survey is how you capture it. Whether filled out by the customer or your service tech, this survey is gold for the engineering, warranty, and design teams.

Pop it right after a return or repair event. The data pinpoints root causes so you can prioritize fixes, reduce warranty costs, and stop defect echoes.

With this smart tool, you’re able to: * Track repeat defects you’d otherwise miss * Collect top-notch evidence for engineering * Prove to your warranty manager that, yes, it is always the gasket

Plus, you’ll find that customers love their chance to vent—and you really want that feedback, warts and all.

5 Sample Questions

1. What was the primary reason for returning the product? (Dropdown list)

2. How long did the product function before the defect occurred? (Days/Weeks)

3. Did the defect pose any safety risk? (Yes/No)

5. Attach photos or descriptions of the defect for engineering review.

Every answer here speeds up quality investigations—and makes your next product launch nearly bulletproof.

Continuous Improvement Feedback Survey (Kaizen Events)

Why & When to Use

Picture this: A bunch of energized employees, sticky notes everywhere, everyone tossing out ideas. That’s a kaizen event in action. But your real continuous improvement magic happens after, with feedback surveys that scoop up all those golden ideas.

You should send these surveys after any blitz or monthly quality roundtable. The goal? Find out what’s working, what’s not, and keep that improvement engine roaring.

You get to: * Pinpoint waste and quality defects at the source * Hunt down fast wins to boost morale * Ask what training (or donuts) would help the team
