The baseline
Which plan is being measured against.
The part
What it is
The first committed plan. Measuring against the current plan produces an organisation that is always on schedule and always late.
Where the plan was rebaselined, that is itself worth recording, since frequent rebaselining is a form of slippage.
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.
