Van Wijnen, a prominent construction company in the Netherlands, recognized the need for change to future-proof their business due to the current housing shortage, limited resources, and rising construction costs. To address this, they implemented a CTO strategy and developed a modular housing platform, with a fully digitalized sales process and customer journey. The manufacturing process is file-to-factory based, using a new and highly automated factory, reducing the sales process lead time by 50% and enabling the construction of a house or apartment in just one day. This 100-year-old company's ETO to CTO transition showcases how CTO can strengthen and future-proof a business, with real-life examples of their implementation of CPQ, PDM, Design Automation, Integration platform, Autodesk Inventor, PLM, and changes to processes and ways of working.
