Multivariant product lines

Manufacturers of all business areas are increasingly forced to differentiate their product lines in order to satisfy the customer needs and to successfully compete within their markets. A common example are automotive manufacturers providing the opportunity to configure their cars down to the smallest detail. High customization possibilities usually lead to a wide product variance and therefore high production costs.

Systematic management of variance within product lines is the only profound way to master that complexity. We are convinced that visualizing multivariant product lines with their components and complex constraints in a concise manner plays a vital role in that process.
