Overview

A good PSTI checklist proves that the product was scoped correctly, the three mandatory duties were implemented, the statement or equivalent evidence file is complete for the legal route being used, and the post-market response path is ready before OPSS or a distributor asks questions.

Section 1

Scope and role checklist

Start with the scope memo and role matrix. Without those two documents, the rest of the checklist can be assigned to the wrong party.

Keep one checklist per product family or model group.

  • Relevant connectable product analysis approved
  • Exclusion and boundary rationale retained, including any current Schedule 3 category used
  • Manufacturer importer distributor roles documented
  • UK route to market and product identifiers confirmed

Section 2

Control and statement checklist

Check not only whether the three mandatory controls exist, but whether they match the product as shipped and the statement as issued.

Misalignment between customer messaging and the statement is a common weakness.

  • No universal default passwords control verified
  • Public vulnerability reporting information published
  • Minimum security update period published and current
  • Statement of compliance or summary prepared and retained where required, or Schedule 2A evidence file checked where that route is used
Section 3

Post-market readiness checklist

PSTI readiness includes the ability to handle compliance failures after launch. That means investigation logs, contact paths, and supply-stop decisions must be ready before a live issue appears.

Test the evidence retrieval path as well as the control itself.

  • Compliance-failure escalation path documented
  • Importer and distributor notification templates prepared
  • Retention schedule set to 10 years or longer if the support period runs longer where a statement is required
  • Mock OPSS evidence retrieval exercise completed
