Multiple development models of software applications utilizing different service environments may be annotated with additional information and transformed within a transformation chain into a resulting unified performance analysis model that may be used to evaluate the development models, for example, for simulations and/or analytical sensitivity analysis by utilizing different performance analysis environments. By relating elements of the development models through the transformation chain to elements of resulting unified models, the evaluation may be performed with respect to the resulting/transformed model, but provided to a user in terms of the original development models. In this way, a user of the development models may work with the more-familiar development models, utilizing multiple different performance analysis tools, without having to alter the development models directly in order to obtain the evaluation.
