  This paper is interested in e-commerce for complex configurable
products/systems. In e-commerce, satisfying the customer needs is a vital
concern. One particular way to achieve this is to offer customers a panel of
options among which they can select their preferred ones. While solution
exists, they are not adapted for highly complex configurable systems such as
product lines. This paper proposes an approach that combines two complementary
forms of guidance: configuration and recommendation, to help customers define
their own products out of a product line specification. The proposed approach,
called interactive configuration supports the combination by organizing the
configuration process in a series of partial configurations where decisions are
made by the recommendation.
