Sample preparation brief, dated 12 May 2025

Scope: fictional Harborview Biologics, sample lot HB-2417 (oral solution), packaging line 2. This is a worked example of how to prepare evidence for a batch review. It is not live readiness, it does not track real batches, and it is not a release decision. Follow your approved batch review procedure for what is required.

Readiness areas

Four things to settle before the review meeting

Preparation is complete when the approved evidence is assembled, every gap is a written question with an owner, each reviewer knows their role, and everyone understands that release is decided elsewhere.

Record completeness

Every page, entry, signature, attachment and referenced log is present and matches the executed batch record.

Open questions

Each gap is written as a specific question with the evidence it concerns, the role who can answer it and the date it is needed.

Review roles

The preparer, the quality reviewer and the laboratory contact each know what they check and what they hand on.

Release authority

The release decision belongs to the authorized role in the governed process. Preparation supplies evidence; it does not approve.

Preparation sequence

Illustrative order of work for sample lot HB-2417

Your approved procedure sets the required steps and timing. Use this order to keep the work coordinated.

  1. 1

    Gather the executed record and its attachments

    Collect the executed batch record and each referenced log, printout and report in one set. Check the page count against the record's own page numbering.

  2. 2

    Check completeness against the matrix

    Work through each evidence category below. Mark each one Complete, Open question, Waiting on owner or Not started.

  3. 3

    Write each gap as a specific question

    Name the record, the step or page, what is missing, and which role can answer. Avoid general notes such as 'logs incomplete'.

  4. 4

    Route questions through the established channel

    Send each question to the named role by your department's usual route. Do not alter a record to close a gap; corrections follow the approved correction practice.

  5. 5

    Hand the set to quality review

    Pass the assembled evidence and the list of questions with their current status to the quality reviewer, who confirms what is ready for the review meeting.

Evidence reference matrix: sample lot HB-2417

Authored sample as of 12 May 2025. It is not a system of record or a live work queue.

Evidence category Preparation check Prepared by Sample status
Executed batch record All pages present; entries signed and dated; each correction shows who, when and why Production Complete
Material records Component lot numbers on the record match the receiving records Production Complete
Equipment and cleaning logs Each piece of equipment used has a log entry covering the run dates Production Open question
Laboratory results Every result cited in the record has a matching reviewed report Quality control laboratory Waiting on owner
Deviations and changes Each referenced deviation has a number and a recorded status Quality assurance Open question
Label and packaging reconciliation Quantities reconcile and any difference is explained on the record Packaging Not started

Open questions: a worked example

The same gap, written two ways

Too vague: 'Cleaning logs incomplete for HB-2417?'

Specific and answerable:

  • Question: The batch record (step 14) lists Mixer 2 as used on 8 May, 14:10-17:40. The Mixer 2 cleaning log has no entry for the second shift on that date.
  • Evidence concerned: Executed batch record, step 14; Mixer 2 equipment log.
  • Needed: The log page for that shift, or the equipment owner's documented explanation.
  • Asked of: The second-shift production lead, through the department's usual route.
  • Needed by: The day before the quality review.

A reviewer can read the specific version and act on it without searching the record. The question closes when the answer is documented through the approved process, not when it is removed from the list.

Handoff order from preparation to release authority

  1. Evidence assembled

    Production gathers the executed record and attached logs and checks page counts.

  2. Completeness check and questions raised

    Contributors mark each evidence category and write each gap as a specific question with a named role.

  3. Questions answered

    Owners respond through the established channel. Answers are documented under the approved practice.

  4. Quality review

    The quality reviewer examines the assembled set and the status of each question.

  5. Handoff to release authority

    The authorized role receives the review outcome through the separately governed release process. That decision is not made on this page.
