Paper details:In approximately 10-12 double-spaced pages discuss the planning steps, possible recovery options, and recommended testing requirements needed to support a successful business contingency/continuity of operations environment. Finally, the paper should include your recommendation for a proposed 24-month cycle business contingency testing plan — what should be tested and how the test should be conducted. Perhaps ranking possible critical corporate assets with the type of testing (i.e., plan reviews, table-top exercises, or perhaps up to and including full blown backup and recovery tests) You should take into consideration costs associated with the recommended testing process — not only personnel and equipment but also production costs.

Prepare your paper in Word. Include a minimum of 5 sources. The citations and the reference list in the paper should be formatted in accordance with APA 6th edition guidelines. Note: Also include a cover page, a one-paragraph abstract, a table of contents and any appendix (if necessary), which do not count toward the regular length of the paper.
