The alternatives

Everything the customer would consider instead.

The part

What it is

Direct competitors, substitutes from other categories, building it internally, and continuing as they are.

Ranked by how often they actually appear rather than by how seriously the organisation takes them.

The smallest level

The attributes it carries

Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
