Model-based design and V-Cycle-based development processes address the need for managing complexity, and to some extent, efficiency in product development.

Today's automotive, commercial vehicle, and aerospace systems are unparalleled in terms of performance, safety, and feature-rich content. This product evolution over the past decade has been fueled by progress made in the field of mechatronics that enabled the complex management and precise control of these vehicle systems. Complexity has multiplied with every new innovative feature that gets included in these systems, as the competitive pressure to continuously evolve shows little sign of abating.

From an engineering perspective, the development process evolved using model-based design (MBD) to address the complexity issue. The MBD process, described as the V-Cycle, is the classic cascading approach taken to develop these systems. However, as project timelines are getting skewed and complexity grows exponentially, it is becoming more important to evolve the design process in a manner that front-loads development tasks and enables parallel design and implementation. Additionally, by enabling early detection and fixes of potential implementation errors, costs in development can be reduced.
