• Discipline silos create added work– Too many point tools & technologies to learn– Skill/expertise resources critical

• Increasing product demands– More complex multi-discipline analysis – Growing reliance on simulation …

• Non-integrated point tool limitations– Multiple proprietary environments

necessitate iterative translations• CAD to CAE geometry translations

– Limits accuracy and increases inefficiency• Barriers to process efficiency

– Numerous models and data silos– Manually dependent processes– Globalization of engineering/CAE/suppliers

increasing data loss• Era of fixed/declining cost of engineering
