9. Industrial Models

Industrial models quickly followed academic efforts. Several different approaches were undertaken, ranging from models proposed by individuals with extensive industrial experience to models proposed by large industrial consortiums. Two representative industrial models are the five-step model by Cabena et al., with support from IBM and the industrial six-step CRISP-DM model, developed by a large consortium of European companies. The latter has become the leading industrial model, and is described in detail next.

The CRISP-DM (Cross-Industry Standard Process for Data Mining) was first established in the late 1990s by four companies: Integral Solutions Ltd. (a provider of commercial data mining solutions), NCR (a database provider), DaimlerChrysler (an automobile manufacturer), and OHRA(an insurance company). The last two companies served as data and case study sources.

The development of this process model enjoys strong industrial support. It has also been supported by the ESPRIT program funded by the European Commission. The CRISP-DM SpecialInterest Group was created with the goal of supporting the developed process model. Currently, it includes over 300 users and tool and service providers.
