Once software begins mixing dates in both the 19xx and 20xx ranges, errors of varying degrees can result. In some cases, the software may fail immediately without completing its operation. In others, the software may continue to produce erroneous output, which can remain unnoticed. Essence of the Challenge There has been extensive examination of the Y2K challenge and ways to address it. Technical experts tend to talk about what changes are needed in how software handles and stores date data.
Program managers tend to talk about planning, estimation, and inventory.
Higher-level managers tend to talk about the cost and the diversion of resources. Each person struggling with the Y2K challenge tends to focus on that part of the solution uppermost in his or her mind. The first step in addressing the Y2K challenge is to identify the business considerations. In reality, this risk can only be eliminated for a period of time-the longer the period, the greater the cost. Preserve current operations.
