How to use this document

Copy the template below into your quality system. Replace every <<FILL: ...>> placeholder with your company, system, and process specifics, then route it through your own document control, review, and approval. The filled specimen shows one worked example; adapt the numbers and scope to your operation and verify each cited regulation or standard against the current source before you rely on it.

This is a generic, originally worded starting point. It contains no confidential, proprietary, or employer material, it is drafted with AI assistance and reviewed, it is not legal or compliance advice, and adopting it does not by itself create or prove compliance. See the Disclaimer and Terms.

This is a ready-to-use plan for a person-in-plant (PIP) program covering a specific CDMO relationship or campaign. Replace every <<FILL: ...>> placeholder, confirm the plan’s authority traces to the governing quality or technical agreement, and route it through document control before the campaign starts. A filled specimen follows.

1. Purpose

This plan defines the scope, oversight model, roles, and escalation channel for sponsor person-in-plant presence during <<FILL: campaign / product / unit operation>> manufacturing at <<FILL: CDMO name>>, consistent with the authority granted under the governing agreement referenced above.

3. Oversight model selection

SituationApplicable to this campaign (Y/N)Model selected
First campaign at a new CDMO<<FILL>><<FILL: on-site, full campaign>>
Recent inspection finding or open quality concern relevant to this product<<FILL>><<FILL: on-site until resolved plus one clean campaign>>
Complex or historically failure-prone unit operation<<FILL>><<FILL: on-site for that operation, virtual for the rest>>
Non-recoverable batch (autologous product, short-shelf-life intermediate, high-value single lot)<<FILL>><<FILL: on-site for critical steps regardless of site maturity>>
Mature relationship, clean deviation trend<<FILL>><<FILL: virtual with periodic on-site spot checks>>
Post-event recovery (a 483, a recall, a repeat deviation)<<FILL>><<FILL: on-site, elevated cadence, until CAPA verified effective>>

State the model selected for this specific campaign and the risk basis, referencing the rows above rather than restating the logic each time.

4. Roles and responsibilities

RoleResponsibility
Person-in-plant (sponsor)Observes, verifies against the plan, documents contemporaneously, escalates through the channel in Section 5; never directs operators, touches product or equipment, or signs batch records
CDMO floor quality representativeReceives PIP escalations in real time, decides immediate floor action, opens the deviation
CDMO quality unit (QA/QC)Retains GMP accountability for the batch; disposition authority; owns the CDMO’s CAPA system
Sponsor quality unitReviews PIP reports; owns the sponsor’s own oversight tracker; retains ultimate responsibility for product quality per ICH Q10 Section 2.7
Sponsor technical operations leadApproves this plan and any mid-campaign change to the oversight model

5. Escalation channel

StepActionOwner
1Observation made, documented contemporaneouslyPIP
2Escalated to <<FILL: named role, e.g. CDMO floor quality representative>> within <<FILL: e.g. same shift>>PIP
3CDMO opens a deviation or takes immediate floor actionCDMO floor quality
4Finding logged in <<FILL: CDMO CAPA system / sponsor oversight tracker>> with a named owner and due dateCDMO quality unit or sponsor quality, per Section 4
5Closure verified against the next relevant occurrence, not accepted as claimedSponsor quality unit

6. Reporting

The PIP issues a report per visit or per defined interval using the paired PIP Visit / Trip Report template, distributed to sponsor technical operations and quality leadership and, in a form the CDMO can act on, back to the site.

7. Acceptance criteria for the program

This oversight program is considered functioning as intended when every escalation in Section 5 reaches a named owner and due date in a real tracking system, every report reaches both sponsor leadership and the site, and no verbal commitment from CDMO staff goes untracked past the visit in which it was made.

Filled specimen

Acme Therapeutics, autologous CAR-T fill campaign at Meridian Fill Services, third campaign at this CDMO.

FieldEntry
ScopeBatches 7 through 9, fill and finish operations only
Situation applicableNon-recoverable batch (autologous product); mature relationship with a clean deviation trend across the last two campaigns
Model selectedHybrid: on-site for fill and viral inactivation steps, virtual for formulation and labeling, stepped down from full on-site presence used in the first campaign
Escalation channelPIP escalates to the CDMO’s floor quality representative within the same shift; findings logged in the CDMO’s electronic CAPA system, with a copy in the sponsor’s own oversight tracker for visibility
Acceptance resultAll three batches completed with two escalated observations, both logged with a named owner and due date, one closed and verified against the next batch’s changeover, the other still open and tracked into the next campaign’s plan

Common inspection findings this plan prevents

  • A PIP program with no documented basis in the governing quality or technical agreement.
  • An oversight model applied uniformly regardless of site maturity or product risk, with no recorded rationale for the level chosen.
  • Escalations that happened verbally with no channel or owner defined in advance.

How to adapt this plan

  1. Confirm the governing agreement referenced in the header actually grants the access this plan assumes; add the language if it is missing before the campaign starts.
  2. Select the oversight model in Section 3 from the actual risk situation, not the model used last time by default.
  3. Name real roles, not placeholders, in Sections 4 and 5 before the campaign begins.
