Resourcing · The resource estimate · Element

The effort

How much work it takes, in people-weeks.

The part

What it is

Working weeks rather than calendar weeks. The two differ by roughly a third once holidays, meetings and other commitments are counted.

Recording confidence alongside the estimate is what distinguishes a considered figure from a guess with a decimal point.

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.
