The options

Each route costed and timed honestly, including the one nobody favours.

The part

What it is

The favoured route is usually costed carefully and the alternatives sketched, which guarantees the comparison confirms the preference.

Acquisition costs in particular are consistently understated, because integration cost sits outside the purchase price and outside the business case.

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.
