The trajectory
The direction margin is actually moving as the organisation grows.
The part
What it is
The assumption is that margin improves with scale. In service-heavy businesses it frequently deteriorates, because service cost grows faster than the pricing does.
Measuring the actual direction over several periods is the only way to know which case applies.
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.
Margin
Actual margin by period, so the direction is measured rather than assumed.
Percentage shared typePeriod
The period each reading covers, kept consistent so the trend means something.
Period shared typeDirection
Improving, flat or deteriorating — the answer the model exists to produce.
