Department of Defense, Year 2000 Management Plan, Version 1.0.

Year 2000 (Y2K) is the term used to describe the potential failure of information technology (IT) systems prior to, on or after January 1, 2000. This potential exists because of the widespread practice of using two digits, not four, to represent the year in computer databases, software applications, hardware, and microchips. Difficulties will arise in the Y2K when our systems will be unable to differentiate it from the year 1900. The associated, but unrelated, calendar anomaly that must be included in the Y2K systems repairs is the fact that Y2K is a leap year unlike most other century dates. The DoD inventory of hardware and software consists of more than three decades of IT development. The goal is to have all DoD systems certified ascertified as Y2K compliant and implemented not later than November 1, 1999. This will be accomplished through the elimination, replacement and/or modification of existing systems as they move through the phases. The DoD Year 2000 Management Plan focuses on Y2K resolution efforts throughout the DoD. It provides the overall DoD strategy and guidance for inventorying systems, prioritizing systems, retiring systems, and monitoring progress. The DoD AEs CIO has overall responsibility for overseeing the DoD AEs solution to the Y2K problem. DoD Components are responsible for awareness, assessments, renovations, validations, and implementation actions. The overall goal is to provide a DoD-wide coordinated effort that ensures no system is adversely affected by Y2K problems prior to, on, and after January 1, 2000.
