Quality Assurance (QA)

Quality Assurance (QA) – Oversight & Release Authority

This topic is part of the SG Systems Global regulatory & operations glossary.

Updated October 2025 • Quality Management & Release • QA, Regulatory, Manufacturing, Supply Chain

Quality Assurance (QA) is the independent function that designs and governs the quality system, assures compliant execution, and exercises final authority over product disposition. In regulated environments, QA is the organizational conscience: it defines the rules, proves they work, and withholds release until the evidence shows the product was made, tested, labeled, and distributed under control. QA oversight is anchored in standards like GMP, the ICH Q10 Pharmaceutical Quality System, and—where applicable—ISO 13485 for medical devices. Its authority spans policies and Document Control, SOPs and training, Management of Change, deviations and CAPA, validation (Process Validation, PPQ), and finally batch release/disposition.

“QA is responsible for the system, independent judgement, and the signature that says ‘this product can go to customers.’”

TL;DR: QA designs and enforces the quality system and holds release authority. It governs policies, documents, changes, deviations/NC and CAPA, validation (PV, IQ/OQ/PQ, CPV), data integrity (21 CFR Part 11, Annex 11), labeling/serialization, supplier quality, and distribution quality (GDP). QA’s independent review of eBMR, test results, and deviations culminates in Lot Release/Finished Goods Release.

1) QA’s Mission and Mandate

At its core, QA assures that products are consistently fit for use and compliant with law and registration commitments. It does this by establishing a documented quality management system (QMS), verifying adherence, and acting as an independent approver of critical decisions like release, recalls, and major changes. In pharma and biotech, QA often represents the Marketing Authorization Holder and interfaces with Qualified Persons (where applicable) but remains distinct: QA organizes the system so those legally accountable individuals have reliable evidence to sign. In device, QA ensures the design and production environment meet ISO 13485 requirements and supports the DHR/DHF chain of evidence. In food and cosmetics, QA safeguards consumer safety under HACCP plans or MoCRA expectations.

2) QA vs. QC—Different Roles, Shared Goal

QA builds and governs the system; QC performs testing and measurement. QA writes and approves the procedures, trains the organization, and reviews evidence for release. QC executes validated methods (often in LIMS/ELN), manages standards and instruments (e.g., HPLC), and reports results that QA later evaluates. When results fail or drift (OOS/OOT), QC investigates technically while QA assures unbiased investigation quality and product impact assessment, then approves disposition and CAPA.

3) The QA System—Policies, SOPs, Training, and Audits

QA establishes the governance backbone: a hierarchy of policies, SOPs, work instructions, and forms under formal Document Control. Effective documents are versioned, role‑based, and retrievable. Training plans guarantee personnel are qualified before performing tasks. QA also runs the Internal Audit program to verify execution matches intent, and it orchestrates the Annual Product Review (APR)/Product Quality Review (PQR) process that transforms data into management insights and improvements.

4) Release Authority—Batch Disposition and Product Status

Release is QA’s most visible authority. Before approving lot disposition and finished goods release, QA verifies that manufacturing followed the current, effective MBR/MMR; results meet specification; deviations and changes are closed or risk‑assessed; labels and certificates are correct; and serialization/traceability events (if required) are complete. With eBMR, QA performs review‑by‑exception using system flags, audit trails, and electronic signatures. Product status control (e.g., Quarantine, Hold, Released) must be enforced in WMS so nothing ships early or without authorization.

5) Data Integrity—Trustworthy Records and Decisions

QA owns the integrity of the evidence it reviews. That means establishing and auditing controls for unique users and e‑signatures (Part 11/Annex 11), immutable audit trails, validated systems (CSV and GAMP 5 guidance), and defensible retention/archival. QA also sets rules for handling test data (raw chromatograms, balances, machine vision images), forbids “trial” runs that contaminate production datasets, and ensures data are contemporaneous and attributable—the spirit of Data Integrity and ALCOA‑plus principles.

6) Supplier & Material Quality—Right First Time Starts at the Gate

QA defines qualification and surveillance of suppliers; it sets acceptance criteria and escalation pathways. Upon Goods Receipt, materials enter Quarantine pending Incoming Inspection and CoA verification. Failures are documented with NCR/NCMR, dispositioned by MRB, and chronic issues escalate via SCAR. QA verifies that genealogy connects raw lots to finished goods and that supplier changes trigger NoC review and—if needed—requalification.

7) Manufacturing Execution—From Validated Instructions to Evidence

QA approves the MMR/MBR and ensures execution under the MES. MES should enforce line clearance, role permissions and dual verification, device interfaces (e.g., gravimetric weighing, machine vision), IPC, and SPC control limits. QA steers validation—IQ/OQ/PQ for equipment and PV/PPQ for process—then assures ongoing control via CPV. Where recipes change, QA enforces MOC/Change Control and confirms impact testing before re‑release.

8) Laboratory Controls—Methods, OOS/OOT, and MSA

QA ensures analytical methods are validated or verified, transferred under control, and executed by trained analysts. It defines OOS and OOT pathways, including immediate containment, hypothesis testing, and reportable conclusions. Data are captured in LIMS/ELN with the same data integrity rules applied to manufacturing. When measurement variation matters, QA promotes MSA and gauges R&R to ensure decisions (release vs reject) are statistically sound.

9) Packaging, Labeling & Traceability—Patient Safety at the Interface

Mislabeling is one of the highest risks QA manages. QA controls Labeling Control (artwork ownership and change approval), at‑line label verification, and—where applicable—global identifiers like GS1 GTIN, SSCC, and unit serialization. Serialization and event exchange via EPCIS strengthen genealogy and recall readiness. Country declarations such as COO and COI should be verified during batch documentation review and again at shipment authorization.

10) Distribution Quality—Storage, Handling, and Handover

QA’s remit extends into warehouses and logistics under GDP. It approves storage conditions, validates packaging and shipper qualification where needed, and assures status control is enforced in the WMS, from Quarantine to Released. QA requires FEFO/FIFO, expiration control, and scan‑verified handover at Dock Loading. Shipping documentation must match batch records, and any cold‑chain or hazard controls are monitored via Environmental Monitoring or equivalent data logging programs.

11) Risk Management—From PFMEA to Control Plans

QA embeds risk thinking into the QMS. It facilitates PFMEA and, where appropriate, FMEA, HAZOP, and hazard‑based food safety plans (HACCP). It turns high‑risk steps into a documented Process Control Plan (PCP)—with IPC checks, SPC limits, and label/identity verifications—so risk controls are embedded in execution, not just described on paper. QA also promotes statistical capability (Cp/Cpk) and continuous improvement methods (Lean, Kaizen).

12) Change Control—Managing the Inevitable

QA governs changes to materials, methods, equipment, software, labels, and sites using MOC/Change Control. Each proposal is risk‑assessed (linking back to PFMEA/PCP), impact‑tested, and—if applicable—subject to Notification of Change to customers or regulators. Where labels or serialization are impacted, QA assures re‑OQ and controlled roll‑out so no mixed‑artwork or wrong‑code incidents occur on the shop floor.

13) Deviations, CAPA, and Effectiveness

When the system is stressed, QA leads with clarity. Deviations and NCs are logged quickly; containment is immediate; root cause uses structured methods; CAPA actions are specific, time‑bound, and verified for effectiveness. For materials, QA leverages MRB and SCAR. Lessons learned feed APR/PQR and updates to SOPs and control plans so the same failure mode is less likely, or impossible, to recur.

14) People, Culture, and Right‑First‑Time

QA’s influence is as much cultural as procedural. It champions a “right‑first‑time” mindset, trains on data integrity behaviors, and recognizes operators who prevent errors by calling out risks early. QA fosters visual controls (poka‑yoke, boards), ergonomic safety (HFE), and disciplined changeover (line clearance)—all of which reduce defects. It sets meaningful KPIs and reviews them with operations so quality drives performance, not just compliance.

15) QA Metrics—Proving Control and Performance

  • Release lead time: Batch completion to QA disposition; aim for review‑by‑exception in eBMR.
  • Right‑first‑time (RFT): First‑pass approval rate of batch records and CoAs.
  • Deviation and CAPA cycle time: From detection to verified effectiveness; recurrence rate of the same root cause.
  • OOS/OOT closure: Timeliness and proportion with confirmed assignable cause.
  • Change velocity: On‑time closure of MOC/Change Control.
  • Supplier quality: SCAR count, closure time, and MRB scrap/rework trend.
  • Process capability: Cp/Cpk on critical CTQs; OEE trend for stability.
  • Distribution quality: GDP deviations per 1,000 shipments; dock scan exceptions at handover.

QA should correlate these indicators to customer outcomes (complaint rate, returns) and business health (yield, OTIF, lead time) to demonstrate value beyond compliance.

16) How This Fits with V5 by SG Systems Global

V5 Solution Overview. The V5 platform is built for QA governance. Configuration is versioned, evidence is attributable, and cross‑module interlocks (identity, status, signatures) are testable and reportable—ideal for QA oversight and release readiness.

V5 QMS. In the V5 QMS, QA codifies policy and SOPs with approval workflows, enforces MOC/Change Control, manages deviations/CAPA, supplier issues via SCAR, and assembles APR/PQR evidence—under Document Control with audit trails.

V5 MES. The V5 MES executes effective‑dated MBR/MMR, captures eBMR with audit trails and e‑signatures, and enforces IPC/SPC. QA uses review‑by‑exception dashboards to accelerate yet strengthen release decisions.

V5 WMS. The V5 WMS enforces status discipline (Quarantine → Hold → Released), Directed Picking, label and serialization verification (GTIN, SSCC), and compliant handover at Dock Loading—turning QA rules into barcode‑enforced behaviors.

Bottom line: With V5, QA turns from “after‑the‑fact reviewer” into a real‑time control partner. The same interlocks QA requires are the ones the platform applies at weigh, mix, test, label, store, and ship.

17) FAQ

Q1. What is QA’s legal responsibility for release?
QA is accountable for ensuring that each lot is manufactured, tested, labeled, and documented in accordance with applicable regulations and approved procedures. QA’s release (or withhold) decision is based on independent review of complete, trustworthy records—often an eBMR—plus resolution of deviations and changes, and verification of labeling and traceability events.

Q2. How does QA ensure data integrity without slowing the plant?
By building integrity into the workflow: unique users and meaningful e‑signatures (Part 11), enforced sequences in MES, at‑line barcode label checks, and exception‑based dashboards so QA reviews what matters most—fast and thoroughly.

Q3. Who owns deviations and CAPAs—the area or QA?
The area initiates and investigates; QA assures method quality, approves root cause, risk assessment, and CAPA, and verifies effectiveness. For supplier issues, QA may issue a SCAR and link to MRB dispositions.

Q4. What does “review‑by‑exception” mean for QA?
It means the system flags anomalies—out‑of‑limit IPC results, missing signatures, label mismatches, unclosed deviations—so QA spends time on risk, not on re‑checking every good step. This requires strong MES/eBMR design and validated audit trails.

Q5. How does QA handle label and serialization controls?
QA owns artwork approval (Labeling Control), verifies at‑line label checks, and ensures identifiers such as GTIN, SSCC, and serialization are correct and event data are exchanged (e.g., via EPCIS).

Q6. What triggers re‑validation or re‑qualification from QA’s perspective?
Significant changes to process parameters, equipment/software versions, materials, labeling or site; negative trends in CPV; or critical deviations. QA routes these through MOC/Change Control, defines scope (e.g., partial re‑OQ), and approves plans before resuming routine release.

Q7. How does QA measure its own effectiveness?
By tracking RFT, release lead time, deviation/CAPA cycle time and recurrence, OOS/OOT closure, audit/inspection outcomes, supplier SCAR trends, capability (Cp/Cpk), and business outcomes like OTIF and complaint rate.
