Evidence pack

An evidence pack is a compiled set of records, documents, and supporting artifacts gathered to show that a process, activity, decision, or requirement was completed as intended. In manufacturing and regulated operations, it commonly refers to an organized collection of objective evidence rather than a single document.

An evidence pack may include items such as approvals, revision-controlled documents, training records, inspection results, test data, electronic signatures, traceability records, deviation records, change history, or system audit trails. What belongs in the pack depends on the process being supported, such as batch review, equipment qualification, supplier oversight, first article inspection, or internal audit preparation.

What it includes and what it does not

An evidence pack usually includes the records needed to support a specific claim or review, for example that a work order followed the approved routing, that personnel were trained on the current instruction, or that a nonconformance was investigated and closed. It does not by itself prove that a process was effective or compliant in every respect. It is the assembled evidence set, not the judgment or approval outcome.

The term can refer to either a digital package assembled from multiple systems or a manually collected file. In more mature environments, the pack is often built from MES, ERP, QMS, document control, and training systems so reviewers can trace source records back to the system of record.

How it appears in operations

Operationally, an evidence pack is often used when someone needs a reviewable, time-bounded record set. Common examples include:

• supporting an internal or customer audit
• assembling records for batch or lot release review
• documenting a supplier or outsourced processing event
• showing completion of corrective action tasks
• supporting first article, inspection, or change control activities

In digital workflows, an evidence pack may be generated automatically from linked records, attachments, and audit trails. In manual workflows, it may be assembled as a PDF bundle or structured folder with indexing and references.

Common confusion

Evidence pack is often confused with an audit trail, but they are not the same. An audit trail is the chronological system record of actions and changes. An evidence pack may include audit trail extracts, but it is a broader collection assembled for a specific purpose.

It is also different from a dossier or device history record, although those can function as evidence packs in some contexts. A dossier is usually a more formal submission-oriented package, and a history record is typically defined around a product, batch, or unit lifecycle rather than a one-time review need.

Why organization matters

The practical value of an evidence pack depends on traceability, completeness, and source clarity. Reviewers generally need to see where each artifact came from, which version applied at the time, and how the records relate to the event or requirement being evaluated.
