The signal set
What each personalisation is based on — stated preference, observed behaviour or inferred attribute.
The deliverable
What it is
Stated preference is accurate and scarce; observed behaviour is abundant and ambiguous; inference is abundant and frequently wrong. Most personalisation runs on the third.
Recording which signal drives which element is what makes an incorrect personalisation diagnosable rather than mysterious.

Personalisation covering a third of customers means the default is the majority experience, and it is usually undesigned.
The other components in the signals
The accuracy
How often each inference is right — because a wrong inference is experienced as being misunderstood.
LearnThe correction
How a customer can fix a wrong inference — because a visible and correctable inference is tolerated and an invisible wrong one is not.
