Practical GDP example — supplementary reading
If a GMP record contains an error, follow the approved site procedure. For a paper entry, a typical controlled correction preserves the original entry legibly (for example, one line through the incorrect value), identifies the correction, and records the responsible person's initials or signature, date and reason where required. Never obscure or erase the original entry, use correction fluid, or invent an activity time.
If an entry was missed, make a clearly identified late entry using the actual entry date/time and an explanation consistent with the applicable procedure; do not backdate. Independent verification or second-person checks apply where required by regulation, approved procedure or risk controls, not automatically to every GDP correction.
Example: An operator discovers that a process step's time was omitted. Preserve the record, promptly inform the responsible supervisor or QA as required, establish what reliable contemporaneous evidence exists, and document a traceable correction or deviation under the approved procedure. Never estimate a time and present it as observed fact.

Readable guide to the video diagrams
Text descriptions of the main slide relationships, in presentation order. Use these with the narration transcript and companion reading. Arrows summarize relationships; they do not replace site procedures or prescribe a universal workflow. The repeated right-hand panels are reminders, not additional mandatory steps.
- Quality system: people, processes and oversight work together.
- Management responsibility: lead, resource and review.
- Risk management: assess, control and review, proportionate to product impact.
- Deviation/CAPA: document, investigate and verify effectiveness.
- Change management: propose, assess and approve before implementation.
- Documentation: instruct, execute and record.
- Data integrity: attribute, preserve and retrieve complete, trustworthy records.
- Expired calibration example: hold, assess and document; evaluate instrument status and product impact.

00:00:00 A pharmaceutical quality system, often called a PQS, brings
00:00:04 together the people, processes and management arrangements used to maintain medicine
00:00:08 quality. Good Manufacturing Practice is a fundamental part of this system.
00:00:14 A strong quality system defines responsibilities,
00:00:17 establishes procedures, monitors performance and
00:00:21 supports continual improvement. It does not rely on final product testing alone.
00:00:26 Senior management is accountable for establishing an effective pharmaceutical quality system
00:00:31 and providing suitable resources. Responsibilities
00:00:35 and authorities should be clearly defined.
00:00:38 Quality units, production teams, engineering and other functions must work together,
00:00:43 while preserving required independent quality
00:00:45 decisions. Management review uses information about
00:00:49 performance, problems and improvement opportunities to guide action.
00:00:54 Quality risk management provides a structured way to assess, control, communicate
00:00:59 and review risks to product quality. The level of formality, effort
00:01:03 and documentation should reflect the risk and available knowledge. Risk assessments
00:01:08 are not a substitute for meeting regulatory requirements. For example, the
00:01:13 criticality of a temperature sensor depends on its intended function and
00:01:18 potential effect on product quality.
00:01:20 When work departs from an approved procedure or expected result, the
00:01:24 event should be documented and evaluated through
00:01:27 applicable quality procedures. Investigation
00:01:30 depth should be proportionate to the potential impact. Corrective and preventive
00:01:34 action, or CAPA, should address identified causes where
00:01:38 appropriate. Effectiveness checks help determine
00:01:41 whether the action achieved its intended
00:01:44 outcome. Not every deviation requires the same investigation or CAPA.
00:01:50 Changes to equipment, processes, software, facilities or documents can affect validated
00:01:55 status and product quality. A formal change management process evaluates proposed
00:02:00 changes before implementation. The assessment considers
00:02:04 technical impact, regulatory implications, validation
00:02:08 needs, training and required approvals. After
00:02:11 implementation, the organization verifies that
00:02:14 the change was completed as intended and that necessary evidence is available.
00:02:19 Good documentation practices help ensure that instructions are clear and records
00:02:24 accurately describe work performed. An approved
00:02:27 standard operating procedure explains how
00:02:30 to perform a defined activity. A completed record provides evidence of
00:02:34 what actually happened. Entries should be accurate, legible, attributable and made
00:02:40 at the time of the activity, according to applicable procedures. Corrections
00:02:44 must preserve the original information and remain traceable.
00:02:49 Data integrity means that information is
00:02:52 complete, consistent and accurate throughout
00:02:54 its lifecycle. The ALCOA principles include attributable,
00:02:59 legible, contemporaneous, original and accurate.
00:03:03 Additional expectations often described as A
00:03:06 L C O A plus include complete, consistent, enduring and available.
00:03:11 These concepts apply to both paper and electronic records. Access controls,
00:03:17 audit trails and record retention should be appropriate to the system and its risks.
00:03:22 Consider a manufacturing vessel whose critical instrument has an expired calibration
00:03:27 status. The operator should not simply ignore the finding. The equipment
00:03:32 suitability and potential product quality impact must be assessed under approved
00:03:37 site procedures. The decision, rationale and any necessary corrective action should
00:03:43 be documented. This example connects the
00:03:46 pharmaceutical quality system, risk management
00:03:49 and good documentation practices to a real operational decision.
