Architectural decisions are sadly lost during architectural construction processes.
The present viewpoints of the architecture generally do not include the design decisions explicitly as part of their architectural knowledge (AK).
Design decisions are not shared and/or reused.
It’s hard to recreat decisions when they haven’t been documented before.
To continue with the initial work presented at EWSA05.

MotivationMotivation
Changes on existing teams.
Traceability issues.
Explain the rationale by which the decisions were made.
Lost of Architectural Knowledge.
Lack of specific notation.
