The cost

What each tool costs, including the parts that are not the subscription.

The part

What it is

Licence cost is visible; administration, integration and the time spent working around limitations are not, and they frequently exceed it.

Cost per active user is the figure that reveals the tools worth attention, and it requires the utilisation data to compute.

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.

Annual cost
Licence and subscription cost per year.
Money shared type
Active users
Actual users rather than seats, which is a different number.
Number shared type
Administration time
Time spent maintaining it, which is real cost that appears nowhere.
Duration shared type
