A modular structure makes circular strategies easier because parts can be repaired, replaced or upgraded without discarding the whole product. When component maintenance is already common, the organisation has a practical base for circular service models.
For manufacturing companies, modularity connects design and business model. It supports spare-part logistics, refurbishment, remanufacturing and longer service contracts. The product becomes easier to keep in use, and the producer can retain more value from knowledge, components and customer relationships over time.
