Post-Market Surveillance Explained: A Test Shows One Day

Post-Market Surveillance Explained: A Test Shows One Day

Business Pill · Keep watching after launch

Post-market surveillance means watching a product after it is on sale, in real use, not only before launch. The video shows a shop that tests a coffee machine for one afternoon, buys it, and finds months later that the coffee tastes bitter.

A short explainer video, under a minute. The shopkeeper and the helper are an illustration of the idea.

At a glance

What Post-Market Surveillance Is

Watching a product after it is on sale has a name: post-market surveillance.

Before and After Launch

The video sets two views side by side. Before launch there is one test, in a controlled place.

Why It Matters

The video turns this into one question: who is watching it after the test?

The Short Answer

A shop tests a new coffee machine for one afternoon. It works perfectly, so the shop buys it.

Months later, the coffee tastes bitter. The shopkeeper protests, but it passed! A helper says the test was one afternoon.

What Post-Market Surveillance Is

Watching a product after it is on sale has a name: post-market surveillance. It means watching the product in real use, not only before launch.

Before and After Launch

The video sets two views side by side. Before launch there is one test, in a controlled place. After launch the checking keeps going, in real use.

The board’s last row says what each shows. The first shows how it can work. The second shows how it does work.

The Honest Limit

A test is a snapshot. Watching only helps if someone reads the signals and acts on them, and it costs effort, every day.

Where This Shows Up in AI Business Today

Our report on the UK government’s response on regulating AI in healthcare says the response describes a “conscious shift towards ongoing assurance rather than overreliance on pre-market assessments and passive adverse event reporting”. The report also says the MHRA’s AI Airlock page names post-market surveillance as its current priority regulatory challenge area.

This is the lesson’s idea in a new setting: a check before launch, and watching afterwards. The report presents all of it as the government’s own statements of intent, and this publication verified none of it independently.

The Question to Ask

  1. Who is watching it after the test?

How This Concept Connects

AI Evaluation as AcceptancRed TeamingKill SwitchThe Notification ClockPost-Market Surveillance
  • AI Evaluation as Acceptance Test contrasts with Post-Market Surveillance. An acceptance test decides before shipping; post-market surveillance keeps checking in real use because a test shows one day.
  • Red Teaming (lesson unlocks soon) contrasts with Post-Market Surveillance. Red teaming attacks before launch and never proves there are no holes; surveillance keeps watching in real use.
  • Kill Switch (lesson unlocks soon) contrasts with Post-Market Surveillance. Surveillance is the alarm that tells you; a kill switch is the owned stop that acts.
  • The Notification Clock (lesson unlocks soon) builds on Post-Market Surveillance. Watching in real use is how a maker spots a flaw after sale, and the notification clock starts the moment it does.
