The effort cost

What places that cannot be bought require instead.

The part

What it is

Participation, contribution, relationship building and time. These places are frequently the most valuable and the least budgeted.

The effort is real and should be costed, or it will be assigned to someone who already has a full week.

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.

Duration shared type
Whose time
Who has to do it, since it is rarely delegable.
