October 2011. Retrieved 26 March 2013.〕 IBM also aided in the development of the model.〔(''Disaster Recovery Levels.'' ) Robert Kern and Victor Peltz. IBM Systems Magazine. November 2003. Retrieved 26 March 2013.〕 Although the original published concept dates back to the 1990s, specialists in business continuity planning (BCP) and in disaster recovery continue to use the seven tiers to illustrate continuity capabilities and costs at a very high level.〔(''Disaster Recovery Levels.'' ) Robert Kern and Victor Peltz. IBM Systems Magazine. November 2003. Retrieved 26 March 2013.〕 The definitions for the various tiers have been updated as technology has evolved in support of business requirements and their associated Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs).〔 (''Business Continuity: The 7-tiers of Disaster Recovery.'' ) Recovery Specialties. 2007. Retrieved 26 March 2013. 〕 ==Tier levels== When the SHARE Technical Steering Committee, working with IBM, described the levels of service for disaster recovery in the late 1980s, it produced a model that used Tiers 0 through 6. As a result of the introduction by IBM of their Geographically Dispersed Parallel Sysplex (GDPS) system, which allowed for an organization to manage end-to-end application and data availability across multiple geographically separate sites, an additional seventh tier was added to represent the industry's highest possible level of service availability.〔(''Disaster Recovery Levels.'' ) Robert Kern and Victor Peltz. IBM Systems Magazine. November 2003. Retrieved 27 March 2013.〕 The seven tiers of business continuity solutions offer a simple method to define current service levels and associated risks.〔(''Continuous Operations: The Seven Tiers of Disaster Recovery.'' ) Mary Hall. The Storage Community (IBM). 18 July 2011.
