Design of real time environment application is the most exigent task for the designers comparing to non real time application design. The stringent timing requirement for task completion is the problem to handle at design time. The design complexity is increased manifolds when object oriented design methods are used and task deadlines are introduced at design stage. There are many design methodologies available for the real time systems but as far as the researcher is concerned none addresses all the problems of real time system design specially the issues of deadline inheritance and dynamic behavior of system if deadlines are introduced at early stages of the design. Most of the methodologies leave the task of handling the timing constraints for the implementation phase at the programming language level. In this paper we have proposed a design approach incorporated with our novel design metrics verification for measuring the design of real time environment applications. The metrics are measured for design of a real time weapon delivery system and it is illustrated that how design quality can be assessed before implementation.
