Customization Issues: A Four-Level Customization Model

Implementation of mass customization and product configuration in
companies requires fundamental considerations about how products can fulfil the demand from customers. In order to support such decision-making, a multi-level model for customization is developed. This model identifies four different levels of customization, ranging from the structure level at the bottom, through the performance level and the experience level, to the learning level at the top. The model also has a dual view with customers/demand at one side and product/supplier at the other side. It is a rather general model, which can be applied to many types of products, and typically, product designers must decide how far up in levels the customization should aim. In this paper, the four-level customization model is applied to wheel chairs.
