Quality Control

In This Section, You Will Learn:

• • Why quality control matters
• • Creating Standard Operating Procedures
• • Quality checkpoints
• • Handling defects
• • Consistency systems

Why Quality Control Matters

• Quality = Repeat Business:
• If product quality varies, customers won't return.
• The Trust Factor:
• • Consistent quality builds trust
• • Trust enables higher prices
• • Happy customers refer others
• • Quality issues destroy reputation
• Cost of Quality Issues:
• • Returns and refunds
• • Bad reviews (online and word-of-mouth)
• • Lost repeat customers
• • Damaged brand reputation
• Prevention is Cheaper Than Cure

Standard Operating Procedures (SOPs)

• What is an SOP?
• Step-by-step instructions for consistent production.
• Why You Need SOPs:
• • Same quality every time
• • Can train helpers easily
• • Reduce mistakes
• • Identify problems quickly
• SOP Components:
• 1. Materials list with exact quantities
• 2. Equipment needed
• 3. Step-by-step process
• 4. Time for each step
• 5. Quality checkpoints
• 6. Common problems and solutions
• Example SOP Step:
• 'Step 3: Add 500g of chemical X. Stir clockwise for 3 minutes until fully dissolved. Color should be uniform light blue.'

Quality Checkpoints

• Before Production:
• • Check raw material quality
• • Ensure accurate measurements
• • Clean equipment
• During Production:
• • Follow SOP exactly
• • Check at each major step
• • Note any variations
• After Production:
• • Visual inspection
• • Test product (smell, texture, function)
• • Check packaging integrity
• • Verify labeling
• Create a Checklist:
• ✓ Label straight and bubble-free
• ✓ Cap/lid tight
• ✓ Fill level correct
• ✓ No visible defects
• ✓ Expiry date marked

Handling Defects

• When Defects Happen:
• They will – have a plan.
• Types of Defects:
• • Critical: Unsafe, cannot sell
• • Major: Poor quality, affects experience
• • Minor: Cosmetic, can sell at discount
• Defect Response:
• 1. Remove from saleable stock
• 2. Identify cause
• 3. Fix process to prevent repeat
• 4. Decide: rework, discount, or discard
• Track Defect Rate:
• • Target: Under 5%
• • If higher, review SOP
• Customer Complaints:
• • Respond quickly and professionally
• • Replace or refund
• • Learn from feedback

Consistency Systems

• Ensuring Every Batch is Same:
• • Use exact measurements (digital scale)
• • Same suppliers for materials
• • Same process every time
• • Test samples from each batch
• Batch Tracking:
• • Number each batch
• • Record production date
• • Note any variations
• • Keep samples for reference
• Quality Improvement:
• • Review quality weekly
• • Identify recurring issues
• • Continuously improve SOP
• The Goal:
• Customer can't tell any two products apart
