The growing complexity of today’s products—fueled by ever-increasing software content and coupled with shrinking timelines for delivering new products—requires engineers to “turn the tables” on existing workflows. The core principle of agile Model-Based Design centers on the idea of reducing rework. Typical workflows result in on-product validation at the end of the development cycle. Requirement issues found at that point drive rework—often taking the design through the entire development cycle again. Early integration and validation through agile Model-Based Design provides an opportunity to minimize rework through up-front, rapid iteration on architecture and requirements.
