In this research work a design framework model for real time environment applications driven by novel design metrics has been proposed. Objective is to use these design metrics for measuring the design of real time environment applications. Measurement at the design level can save effort and cost. The existing design methodologies for real time systems are lacking with this measurement aspect. In this research work measurement has been introduced in the form of metrics for the design methodology of the real time system. The metrics are validated and the results are satisfactory. The case study has shown that using these metrics at the design level can reduce design errors for the real time applications. The further research can be carried out for development and implementation of real time application using the proposed real time application design framework model and the design metrics.
