This paper introduces a classification for decisions originating from work performed by architects. With the creation of a new architecture, all observed decisions were documented using an existing taxonomy extended with the introduced classification. In the first four months, 80 decisions were documented. Not all decisions have the same value for the architecture and one needed a classification to reason about importance of decisions. After realization of the first increment of the architecture a sanity check was performed: The architects showed how the six most important design artefacts and the fifteen most important architectural constraints and prerequisites were related. The relationship was via decisions and the classification helps to reduce the work to make and maintain this connection over time. The classification is dynamic and over time decisions can be classified differently. This enables architectural learning by pointing out which decisions were taken too early or had little impact.
