21. Several Design issues remained at “Design Chill”The solution in practice – real world results
22. 6 $7,600/defect* $960/defect* $240/defect* $80/defect * Requirements Phase Development phase Released Product QA/Testing phase Traditional testing methodologies are insufficient80% of development costs are spent identifying and fixing defects Repair Cost Induced Errors DefectsIntroduced DefectsFound HW/SW integration Test Development Operation Integration *Source: 2008 GBS Industry standard study Defect cost derived in assuming it takes 8 hrs to find, fix and repair a defect when found in code and unit test. Defect FFR cost for other phases calculated by using the multiplier on a blended rate of $80/hr
23. 7 Why use Model-Based Simulation and Test? Model-based specifications are Executable early validation and verification of the designs against requirements Visual improved maintainability and communication Model-driven Testing Enables early and repeated testing Bugs are found early; hence easier to fix with less cost Easy to cross-link requirements, model, code and test data and to synchronize this continuously Required for safety standards, like ISO DIS 26262, DO-178B/C, etc. High degree of automation possible Enables parallel development and test of embedded software
24. 8 Rational Solutions for Systems and Software Engineering Visually refine requirements into a robust system using Rational Rhapsody Model Based Systems Engineering (MBSE): A standards-based practice for the development of complex systems across the mechanical, electronic and software disciplines
25. 9 Key Enabling Technologies of the Rational Rhapsody Solution Model Execution Software- Centric Workflow Requirements Visualization Standards-Based MDD Model-Based Testing Team Collaboration
26. 10 Model Execution Simulate & Animate Validate requirements and design early with continual simulation and testing Analyze system functionality for correctness and to determine next steps Visually demonstrate and communicate intended behavior to customer and stakeholders Execute on the target and animate on the host to verify the application is correct
27. 11 Graphical Execution of State Machines and Activity Diagrams Model Execution Visual highlights of system or software state machines and activity diagrams as model executes. Easily answers questions such as, “What state is the system in? What path was taken to reach that state?” Active State Active State Active State
