URS to IQ/OQ/PQ Binding

SAGA-DEMO-0418 · Rev 02 · Approved 2026-03-28

URS-EQ-014 Temperature stability ± 0.3 K — IQ verified
URS-EQ-018 Airflow uniformity — OQ verified
URS-EQ-022 Fill accuracy per batch — PQ pending
URS-EQ-027 Cleaning residue threshold — PQ verified
URS-EQ-031 Spare-parts commonality — IQ waived
URS → IQ → OQ → PQ → Re-qualification Trigger

URS, IQ, OQ, PQ — and the re-qualification question

Equipment validation reads as a chain: a User Requirements Specification sets what the equipment must do, Installation Qualification evidences that it arrived and was set up correctly, Operation Qualification proves it behaves inside its specified envelope, and Performance Qualification shows it delivers the process outcome under real production conditions.

SAGA carries that chain as a single traceable thread. Each URS item binds to its qualifying phase and the acceptance criteria that close it; each IQ, OQ, and PQ protocol carries the URS references it answers; the signature trail reads cleanly from requirement to evidence without a cross-file reconciliation pass.

The harder question is not the initial qualification — it is the re-qualification trigger. A process change, a spare-parts swap, a cleaning-procedure revision: each might re-open IQ, OQ, or PQ, or none of them. SAGA records the change rationale against the original qualification so the risk-based decision is auditable, not reconstructed from memory.

The four phases, read in order

Each phase answers a distinct question, and each phase has its own acceptance shape. The discipline is keeping them separate on the way up and connected on the way down.

  1. User Requirements Specification. What the equipment must do, in process terms. Not "supports 200 L batch" — "delivers fill accuracy within tolerance at the 200 L process rate". The URS is the load-bearing document; every phase below binds back to its items.
  2. Installation Qualification. Evidence that the equipment arrived intact and was installed against specification. Serial numbers, utilities verification, calibration certificates, spare-parts inventory. IQ is a factual record: either every checklist line is closed or it is not.
  3. Operation Qualification. Evidence that the equipment behaves inside its specified envelope — temperature, pressure, flow rate, dwell time. OQ exercises the range, not the point; a qualified envelope is the equipment's operating charter for every batch that follows.
  4. Performance Qualification. Evidence that the equipment delivers the process outcome under real production conditions — batch-realistic loads, real materials, real operators, real cleaning cycles. PQ is where URS items close; once PQ passes, the equipment is in production service and every re-qualification trigger tracks back here.

Our regulatory posture

Adoption looks the same, whatever the equipment state

Whether you are qualifying new equipment at site acceptance, retrofitting in-production equipment whose dossier has drifted, or bringing SAGA into a qualification already in flight, the URS-to-PQ shape stays consistent and the work already done keeps counting.

Greenfield

New validation projects start in SAGA from kickoff — the dossier shape is set the first day, and every artefact lands in the framework as it's authored.

Retrofit

In-production equipment and existing systems can be retrofitted into the framework so ongoing validation work joins SAGA without pausing operations.

In-flight

Mid-engagement validation projects load existing material into SAGA and continue in parallel — switching over fully when the dossier shape is ready.

See SAGA against your hardest qualification

Bring the qualification you are least sure of — a PQ whose URS binding has drifted, an OQ envelope whose re-qualification trigger fires every quarter, a legacy IQ whose signature trail never closed. A focused session, your artefacts in front of us, clear outputs.
