Buying and accepting

Vendor lock-in

What it would cost to leave — and it is a design property of the arrangement rather than a personality trait of the supplier.

Also called Supplier lock-in · Залипание на поставщике

01/What it means

It is rarely malicious and almost always structural. Accounts opened in the supplier's name because it was faster on day one. A proprietary layer nobody else has seen. Data in a shape only their tooling reads. No documentation, because it was never a deliverable. Every one of these is a reasonable local decision and the sum of them is a business that cannot change supplier without rebuilding.

The measurement is a single question asked at any point in the relationship: if this supplier disappeared on Friday, what could not be done on Monday? The answer is the lock-in, in units of work, and it is knowable long before anybody wants to leave.

It also compounds quietly with time, which is why it is worth testing while things are going well. A relationship that is working is the cheapest possible moment to establish that the registrar, the repository, the cloud accounts and the analytics are in the company's name — and the moment it is least likely to be raised.

02/What people get wrong

The supplier is competent and pleasant, so the question feels rude and is not asked. Lock-in is not about whether they would behave badly; it is about what happens if they are acquired, lose the person who knows the system, raise their rates, or simply stop replying. Ask it as an operational question and it stops being awkward — and a good supplier answers it without hesitating.

Where it is measured in practice

The term is a reading taken at a point in a sequence that is already running. These are the sequences, with the place each of them jams.

A piece of paid work, travelling from the sentence that started it to the moment the buyer agrees it is finished and can carry it without the supplier. 6 steps, acceptance by demonstration is the arrangement that fails while looking reasonable.
How to test it

Knowing the definition is not the same as being able to check the figure. These are the procedures that do the second thing.

The definitions are the easy part. Whether the figure on your dashboard was computed this way is a different question, and usually the more expensive one.
