� Change of paradigm needed to (further) increase engineering

efficiency

� From software development to process development

� From feature orientation towards product orientation

� Focus must be on methodology development to support simulation driven engineering of product development

Changing the Paradigm


Process driven approach needed to (further) increase efficiencyProcess driven approach needed to (further) increase efficiency



� More efficient use of existing tools

� Know the Do’s and Don’ts of your software

� Coupling and integration of existing tools

� Moving towards a more complete physical representation of products in

terms of parts, subsystems and systems

� First define simulation process needed to support simulation driven

product development

� Then implement that process
