It is widely recognized that in order to make performance validation an integrated activity along the software lifecycle it is crucial to be supported from automated approaches. Easiness to annotate software models with performance parameters (e.g. the operational profile) and automated translations of the annotated models into "ready-to-validate" models are the key challenges in this direction. Several methodologies have been introduced in the last few years to address these challenges. The tutorial introduces the attendance to the main methodologies for annotating and transforming software models into performance models.
