The drift check

Whether the organisation is quietly closing its own trade-offs.

The part

What it is

Every accepted weakness attracts pressure to fix it, and each individual fix looks reasonable. The sum of them is a lost position.

The check is a periodic reading of whether the trade-offs still hold, which is a strategic question rather than a product one.

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.

Checked
When the trade-offs were last reviewed as choices rather than as backlog items.
Date shared type
Still held
Whether the trade-off is intact, eroding or abandoned.
Status shared type
Pressure source
Where the pressure to close it comes from, which is usually a specific customer or deal.
