During 1980´s simultaneous engineering started to develop. Within framework of this approach
product design, process design and development of all other elements of product success are
understood from the initiation as integrated set of objectives and activities. All activities are
realized simultaneously by the product development team. Very important benefits of this
approach is better meeting of customer needs, shortening time of product design and
development, saving costs, better manufacturability of designed product etc. (Clausing, 1994).
