Architectural Failure
! Results of Architectural Failure
! Implementation and Operation too expensive
! Implementation too heavyweight, needs to much expensive resources
! Implementation not scalable, scaling becomes expensive
! Implementation not flexible, implementing new features becomes expensive
! System Components do not fit, integration becomes expensive
