• Model Based System Engineering Project (MBSE)

• Close collaboration with customers• Facilitated workshops based around

prioritized Use Case Analysis• Issues resolved within days/weeks

• Traditional ( Textual Requirements )• Regular customer design reviews• Design studies main source of issue

resolution• Issues resolved within Weeks/Months• Several Design issues remained at

“Design Chill”

The solution in practice – real world results

Traditional testing methodologies are insufficient80% of development costs are spent identifying and fixing defects

$80/defect * $240/defect* $960/defect* $7,600/defect*

Requirements Phase Development phase Released Product QA/Testing phase*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

Why use Model-Based Simulation and Test?

Model-based specifications areExecutable

– early validation and verification of the designs against requirements

Visual– improved maintainability and communication

Model-driven TestingEnables early and repeated testingBugs are found early; hence easier to fix with less costEasy 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

Summary

Complexity can rapidly increase as you develop products and systems

Finding defects too late in the product lifecycle can be very costly and time-consuming

IBM Rational’s solution for Systems and Software Engineering:

Enables simulation of models and discovery of defects much earlier in the product lifecycle when they are cheapest to fix

Builds in quality from concept to product launch

Ensure designs and products meet market demands and industry requirements
