The document discusses concepts and processes related to operating a Customize-to-Order (CTO) Virtual Organization. It defines key terms like product platform, parameter, module, and product variant. It outlines the main phases of CTO operation: forming the virtual organization, designing the product platform, configuring custom variants, and executing production. Variant configuration generates a bill of materials and routing automatically based on customer selections. Any "white spots" or unspecified components trigger further engineering before manufacturing the variant using an Engineer-to-Order process. Successful new components may then be added back to the product platform.
