Idea
Prediction of quality properties on a model base
for systematic design of software systems performance, reliability, …
Derive performance metrics from the models using
simulation analytical techniques

Current Trends
Extension to ernergy prediction (fortiss, FZI) Meta-Model refactoring (KIT) Traceability to requirements and design decisions (KIT) Repository of recurring design decisions (KIT) Stronger linkage between code and architectures (KIT) Analysis of Scaliability, Elasticity and Efficiency (TUC) Detection of scalability anti patterns (TUC) New analysis framework with explicit metrics and typed measurements (TUC) Reuse of architectural knowledge (Architectural Templates) (TUC)
