Mass customization (Pine, 1993) • Ideal: products meet individual requirements at the price of a mass product à competitive advantage • Key capabilities (Salvador, de Holan, & Piller, 2009) • Understand customer needs and their variability à solution space development à product family: configurable product • A robust process to fulfill differentiated customer needs • Choice navigation capability to support customers in identifying their own solutions Department of Computer Science www.cs.helsinki.fi/juha.tiihonen 3 Juha Tiihonen Configurable products • Pre-designed to meet a given range of different customer requirements ( product family ) • Each delivered product individual is tailored to the individual needs of an individual customer • Each product instance is specified as a combination of pre- designed components or modules. • The product has a pre-designed general structure or architecture or a set of these • There is no need to do creative design as a part of the sales- delivery process (Tiihonen & Soininen, 1997) www.cs.helsinki.fi/juha.tiihonen 4

Configurator • Software system that supports Configuration model efficient and errorless Customer ”rules of the game” specification of individualized of the product products or services requirements • Configurators enable Components (BOM) Configurator representing the variability of Connections? configurable products by Drawings? creation and management of outputs configuration models Configuration • A tool for configuration modeling Produced as specified by • Another tool for the customer or specifies configuration sales person Product individual • Customer receives a product individual according to the specification Department of Computer Science www.cs.helsinki.fi/juha.tiihonen 5 Juha Tiihonen Core concepts and their major relations 6

Research questions • RQ1: What are the concepts central to configuration knowledge? • RQ2: How to construct a practical and computationally well- founded sales configurator? • RQ3: Can users be effectively supported in finding suitable products and services with personalized recommendations? • RQ4: How does service configuration differ from the configuration of physical products? Department of Computer Science www.cs.helsinki.fi/juha.tiihonen 7 Juha Tiihonen Overview • IT tools to support business based on mass customization • Conceptual model for WeCoTin sales configurator representing configuration Service configuration models n • Novel configurator WeCoTin o i t a d n e m m o c e R • How does service configuration differ from the configuration of physical products? • How to apply recommendation technologies that support selection making for/in context Concep- tualization of configurable products? • Sales configurator information systems design theory Department of Computer Science www.cs.helsinki.fi/juha.tiihonen 8 Juha Tiihonen
