This contribution presents a model for process improvement in the area of performance engineering, which is called performance engineering maturity model. The use of this model allows the evaluation of the level of integration and application of performance engineering. It leans against the well-established capability maturity model from the software engineering institute. The model is based on a questionnaire catalog, which was transferred into a web based evaluation form. The results of this anonymous evaluation are analyzed in this contribution. Keywords Performance Engineering, capability maturity model, performance engineering maturity model, process maturity
