Five Layered Model for identification of software Performance Requirements

Identification of performance requirements is important for successful development and deployment of the software product. The acceptance of the software product by the customer depends on the performance requirements which are incorporated in the software. For this, we need to identify all the performance requirements required by all stakeholders. In the literature not many approaches are available for this purpose. Hence, we have proposed a five layered model for identification of performance requirements. The proposed layered model has many advantages over non-layered approaches. As part of this model some rules are also proposed to be used in performance requirements identification process. The layered model is applied successfully on two case studies. The identified performance requirements are validated using a check list and in addition the completeness of the identified performance requirements is computed using a metric.
