You trust your manufacturer. But trust is not enough. I have seen brands trust their factory for years. Then a shipment arrives. The quality is terrible. The fit is wrong. The brand asks, "What happened?" The factory says, "We don't know." The brand had never audited the sample process. They assumed it was good. It was not. I learned this lesson early in my career. A client assumed we were following their process. We were not. They audited us. We improved. The brand’s quality became consistent.
Based on our experience working with hundreds of brands, auditing your manufacturer's sample process is essential for quality control. An audit examines the sample room, the pattern making, the fit approval, and the documentation. For example, last year we worked with a brand from London. They were having quality issues. We conducted an audit of their manufacturer's sample process. We found that the pattern maker was not using the approved spec sheet. The fit notes were not being documented. The factory corrected these issues. The brand's quality improved immediately. That is the power of a sample process audit.
So, how can you audit your clothing manufacturer's sample process? Let me break it down. I will give you a step-by-step framework. I will show you what to check. I will give you a scorecard. And I will tell you what to do with the results.
How Do You Audit the Sample Room and Equipment?
The sample room is the heart of development. I remember a client from New York. They never visited the sample room. They did not know that the factory was using old, broken machines. The samples were poor.
Start your audit by visiting the sample room. Is it clean and organized? Are the machines in good condition? Are there enough sample makers? For the New York client, we found that the sample room had 3 broken machines. The sample makers were sharing 2 machines. Samples were delayed. For woven shirts, check that they have specialized machines for collars and plackets. For knits, check that they have machines for coverstitch and flatlock. For denim, check that they have chainstitch machines for hems. A well-equipped sample room produces accurate samples.
What Equipment Should a Sample Room Have?
A sample room should have:
- Lockstitch machines
- Overlock machines
- Coverstitch machines (for knits)
- Buttonhole machines
- Button attachment machines
- Iron and pressing equipment
- Cutting table and tools
For a sportswear client, they checked that the sample room had a flatlock machine. The factory did. They passed.
How Do You Assess Sample Maker Skill?
Assess skill by:
- Asking about their experience (years)
- Reviewing their portfolio of past samples
- Watching them sew a sample
- Checking the stitch quality on recent samples
For a denim client, they asked to see a sample of a complex wash. The sample maker had 10 years of experience. The sample was excellent.
How Do You Audit the Pattern Making Process?
Pattern making is where the fit is determined. I remember a client from Chicago. They had consistent fit issues. We audited the pattern making process. The pattern maker was not using the spec sheet. He was guessing.
Audit the pattern making process. Does the pattern maker use the approved spec sheet? Are the grade rules documented? For the Chicago client, we found that the pattern maker was using his own measurements. He ignored the client's spec sheet. We corrected this. For woven shirts, check that the pattern includes seam allowance. For knits, check that the pattern accounts for stretch. For denim, check that the pattern includes the correct rise and thigh measurements. Ask to see the pattern files. Are they organized by style number? Are they backed up?
What Should You Check in Pattern Files?
Check that pattern files include:
- All pattern pieces (front, back, sleeves, collar, etc.)
- Grain lines
- Notches for alignment
- Seam allowance
- Size labels
- Date of last revision
For a sportswear client, they checked that the pattern files were backed up on a server. The factory had a backup system. They passed.
How Do You Verify Grade Rules?
Verify grade rules by:
- Asking for the grade rule document
- Measuring the pattern for XS, M, and XL
- Checking that the increments are consistent
- Ensuring the increments match the spec sheet
For a denim client, they measured the rise on patterns for sizes 28, 32, and 36. The rise increased by 0.25 inches per size. The grading was correct.
How Do You Audit the Sample Approval and Documentation Process?
Without documentation, you have no proof. I remember a client from Boston. They approved a sample verbally. Later, they said they did not. The factory had no record. There was a dispute.
Audit the sample approval process. Does the factory document every approval? Are fit notes written clearly? Are photos taken? For the Boston client, we now require a signed approval form for every sample. The form includes the style name, sample round, date, and signature. For woven shirts, the fit notes include collar, placket, and cuff details. For knits, they include neckband and hem details. For denim, they include rise, thigh, and wash details. Ask to see the approval forms for past samples. Are they organized? Can they find a specific style quickly? A good factory has a filing system.
What Should a Sample Approval Form Include?
An approval form should include:
- Style name and number
- Sample round (e.g., "Fit Sample Round 2")
- Date of approval
- List of fit notes (location, issue, change, amount)
- Photos of the sample
- Signature of approver
For a sportswear client, the approval form also included the trim card. The client signed off on the zipper and buttons.
How Are Reference Samples Stored?
Reference samples should be stored:
- In a clean, dry area
- Away from sunlight (to prevent fading)
- In labeled bags or on hangers
- With a tag indicating style, size, and date
For a denim client, the reference sample was stored in a dark closet. The wash did not fade.
How Do You Audit the Sample Timeline and Communication?
Slow samples mean slow production. I remember a client from Seattle. Their factory was always late. They never knew why. We audited the timeline. The factory was not tracking sample start dates.
Audit the sample timeline. Does the factory have a sample calendar? Do they track start and end dates? For the Seattle client, we created a sample tracking system. The factory recorded the date the tech pack was received, the date pattern making started, the date sewing started, and the date the sample was shipped. For woven shirts, a typical timeline is 10 to 14 days. For knits, 7 to 10 days. For denim, 14 to 21 days for wash samples. Ask to see their sample calendar. Are they meeting their own deadlines? If not, ask why. Communication is also part of the audit. Does the factory update you on status? Do they tell you about delays before you ask?
What Should a Sample Calendar Show?
A sample calendar should show:
- Date tech pack received
- Date pattern making started
- Date pattern making completed
- Date sample sewing started
- Date sample completed
- Date sample shipped
- Expected delivery date
For a sportswear client, the sample calendar was shared online. The client could see the status at any time.
How Do You Assess Communication?
Assess communication by:
- Sending an email. How fast do they respond?
- Asking for a status update. Do they provide it?
- Checking if they have a sample coordinator.
- Seeing if they proactively tell you about delays.
For a denim client, they emailed the factory. They received a response in 2 hours. The communication was good.
How Do You Score the Audit and Take Action?
An audit without a score is just an opinion. I remember a client from New York. They did an audit. They did not score it. They did not know if the factory was good or bad.
Create a scorecard for your audit. Score each area: Sample Room (1-10), Pattern Making (1-10), Documentation (1-10), Timeline (1-10), Communication (1-10). A total score of 45-50 is excellent. 35-44 is good. 25-34 is needs improvement. Below 25 is unacceptable. For the New York client, the factory scored 30. They needed improvement. We created a corrective action plan. The factory fixed the issues. The next audit score was 42. For woven shirts, a score below 25 means find a new factory. For knits, the same. For denim, a low score indicates high risk of wash variation. After the audit, share the results with the factory. Create a corrective action plan. Set a date for a follow-up audit.
What Is a Sample Audit Scorecard?
A sample audit scorecard includes:
- Sample Room & Equipment: /10
- Pattern Making & Grading: /10
- Sample Approval & Documentation: /10
- Timeline & Scheduling: /10
- Communication & Responsiveness: /10
- Total: /50
For a sportswear client, their factory scored 48/50. They were very reliable.
What Do You Do with a Low Score?
If the score is low:
- Share the results with the factory manager
- Create a corrective action plan with deadlines
- Schedule a follow-up audit in 30 to 60 days
- If no improvement, start looking for a new factory
For a denim client, their factory scored 22. They switched to a new factory. The new factory scored 45.
