1. Scope and quality objectives

This plan governs quality for Bottling Line 2, which fills, caps, and labels 500 ml glass bottles of sparkling beverages. The objectives are to hold the line's defect rate below 0.5%, achieve a first-pass yield of at least 98%, and keep customer-reported quality complaints under 5 per million bottles shipped.

2. Standards and acceptance criteria

Standard	Source (external / customer / internal)	Acceptance criteria
ISO 22000 food-safety clauses	External	Documented hazard controls verified at audit, no major findings
Fill volume 500 ml +/- 5 ml	Customer / regulatory	Net content within tolerance on sampled bottles
Cap torque 12–18 in-lb	Internal	Torque reading within range; no leakers in seal test
Label placement +/- 1.5 mm	Internal	Label square and within position tolerance on inspection

3. QA activities and checkpoints

Stage / checkpoint	What is checked	Acceptance criteria	QA or QC	Owner	If it fails
Incoming bottles	Glass free of cracks, correct dimensions	Sample passes visual + gauge check	QC	Goods-in inspector	Quarantine pallet, return to supplier
Fill volume (in-process)	Net content of filled bottles	5-bottle sample every 30 min within tolerance	QC	Line operator	Stop line, recalibrate filler
Cap seal (in-process)	Torque and leak test	Torque in range; zero leakers in sample	QC	Line operator	Hold batch, adjust capper
Process audit	Line follows the SOP and records are kept	No major non-conformance against checklist	QA	Quality Manager	Raise corrective action
Final inspection	Label, fill level, cap, coding correct	Sample passes full visual standard	QC	End-of-line inspector	Reject batch to quarantine
Post-delivery review	Customer complaints and returns	Complaint rate under target	QA	Quality Manager	Open investigation, root-cause

4. Roles and responsibilities

Role	Person	Responsibility
Quality Manager	Amara Bello	Owns this plan, sets standards, runs audits, reports to plant leadership
Production Lead	R. Singh	Ensures the line follows the SOP and meets acceptance criteria
Line operators	Shift teams A/B	First-line checks (fill, cap, seal); flag and hold defects
End-of-line inspector	QC roster	Performs final inspection and records results
Plant Manager	T. Okafor	Provides resources and authority; receives monthly quality report

5. Tools and methods

• Inspection / test tools: Checkweigher on net content, torque tester, vision system for label placement, manual visual checklist.
• Tracking system: Plant quality log (non-conformances and audit findings) reviewed at the monthly meeting.
• Sampling approach: In-process sampling every 30 minutes; 100% automated checkweigh on fill volume.
• Documentation: Batch records and inspection sheets retained for 24 months.

6. Metrics and reporting

Metric	Target	Source	Review cadence	Reported to
Defect rate	Below 0.5%	End-of-line inspection	Weekly	Production Lead
First-pass yield	At least 98%	Line output vs. rework	Weekly	Production Lead
Customer-reported issues	Under 5 per million	Complaints log	Monthly	Plant Manager
Audit findings (major)	Zero	Internal audits	Quarterly	Plant leadership

Quality results are reviewed at the monthly Bottling Line 2 quality meeting chaired by the Quality Manager.

7. Non-conformance handling

• Logging: Any out-of-tolerance result is recorded in the plant quality log by the operator or inspector.
• Containment: The affected batch is held in quarantine and physically tagged; the line is stopped if the failure is systemic.
• Disposition: Rework where feasible (e.g., re-cap), otherwise scrap; accept-with-concession requires Quality Manager sign-off.
• Root-cause analysis: 5 Whys led by the Quality Manager for any batch quarantine.
• Corrective / preventive action: Process or maintenance change logged, owner assigned, and effectiveness verified at the next audit.

8. Continuous improvement

• Review cadence: Monthly quality meeting (Check), with this plan reviewed quarterly (Plan/Act) on a PDCA basis.
• Inputs to improvement: Defect-rate and yield trends, audit findings, complaint patterns.
• Improvement owner: Quality Manager drives corrective and preventive actions to closure.
• How gains are locked in: Proven fixes are written back into the line SOP and the inspection checklist.
