Automotive manufacturers and their suppliers need a high degree of process flexibility to respond quickly and efficiently to the market demand. Picture, however, production, purchasing and supply processes not interacting optimally, causing delays which inevitably pushes costs higher. The search for weak points in the supply chain is a major challenge, because common analysis tools cannot holistically capture the already complex processes. The new process mining technology, however, allows for the analysis and visualization of the entire process chain, a task which classic analysis tools fail to accomplish.
