Your own suppliers, and what to ask them

Your own suppliers, and what to ask them. What it costs, who decides, and what usually goes wrong.

For an independent reference point, see European Commission AI regulatory framework.

Both ends at once

You are a supplier and you are a customer

The reference section covers the obligation arriving from above. This is the other end: what you have to require of the machine shop, the finishing house, the design contractor and the software vendor who touch the same information.

Suppliers concentrate almost entirely on the first and are surprised when a prime asks what they require of their own chain.

What to ask

Six questions, not two hundred

  • Do you receive or hold our controlled information, and which?
  • Where does it sit, and who can reach it?
  • What is your current status against the requirement?
  • Who is your named contact for a security incident?
  • Will you tell us within a stated time if something happens?
  • Do you pass these requirements to anybody further down?

Six questions get answered. A two-hundred-question spreadsheet arrives at a small shop with no compliance function, gets filled in by somebody guessing, and produces a file rather than information.

The small supplier problem

Your eight-person machine shop cannot do this

They have no compliance owner, no budget and possibly no idea the requirement exists. Demanding certification from them by a date achieves one of two things: they stop working with you, or they tell you what you want to hear.

Neither improves your position, and losing a capable supplier over a form is a real commercial cost.

What works better

Three options that are not a demand

Reduce what they hold. If they can do the work without the controlled file, or with a redacted version, the requirement largely goes away. This is frequently possible and rarely considered.

Do the handling yourself. Keep the data in your environment and give them access under your controls rather than sending it.

Help them. Share what you learned, point at the free sources, introduce them to the assistance programmes that exist. It costs little and it keeps a supplier.

Contract terms

Four clauses, kept short

What they must protect and to what standard. Notification of incidents within a stated period, to a named person. The right to ask for evidence, proportionately. And an obligation to pass equivalent terms further down.

Long security schedules imposed on small suppliers are signed unread. Four clauses in plain language are more likely to be understood and therefore more likely to be followed.

Records

Keep what you asked and what they said

An assessor may ask how you manage your supply chain, and the answer is the questionnaire responses, the contract terms and the review dates. Held somewhere findable, dated, and refreshed on a cycle.

Annual is adequate for most. Refresh sooner when a supplier's circumstances change or when the work they do for you changes.

The map

Know which suppliers touch what

A list of suppliers, what controlled information each receives, and how it reaches them. This is the supply-chain version of the shop-floor inventory and it is missing about as often.

Building it usually finds two or three suppliers who receive things nobody realised they received, generally because a file was attached to an email in 2021 and the practice continued.

Proportion

Match the demand to the exposure

A supplier who receives a full technical data package is a different proposition from one who receives a dimensioned sketch. Tiering your requirements by what each actually holds is defensible, cheaper, and more likely to be complied with than a uniform demand.
