Disaster recovery plan, disaster readiness, contingency planning, continuity planning, continuous processing plan. These terms are extremely confusing and, although there are subtle differences in the meaning, they are often used interchangeably when referencing the planning process for mitigating the impact of catastrophic events. It’s like the terms statistical process control and statistical quality control. I contend the only real difference in these two terms has to do with the age of the person utilizing them. The so-called DR function is a prime example of a process that has undergone a major evolution with the passage of time (the classic paradigm shift). Only a few short years ago, the vast majority of disastrous events were driven by nature, i.e.: Tornadoes Earthquakes Floods Forest and brush fires Etc.
