 had a significant data mining team. OHRA, an insurance company, was just starting to explore the potential use of data mining.

The first version of the methodology was released as CRISP-DM 1.0 in 1999.

CRISP-DM 2.0

In July 2006 the consortium announced that it was going to start the process of working towards a second version of CRISP-DM. On 26 September 2006, the CRISP-DM SIG met to discuss potential enhancements for CRISP-DM 2.0 and the subsequent roadmap. However, these efforts appear to be stalled. The SIG has not met, updated the CRISP website, or communicated anything to members since early 2007. As of June 22, 2011, the website redirects to an IBM page about SPSS.
