While process documentation developed late is not as effective, it must be recaptured and transcribed before it's forgotten. With the remaining time, it may be well to improve poor Y2K process documentation. It is said of the Y2K process that there can never be too much testing. No amount of rigor or control will prevent all bugs. But each test that uses different tools, methods and criteria uncovers more remaining bugs.
Preventable loss can cost much more than testing.
The most serious problem is the wish to test only for errors that stop a system. Not testing for logic bugs may impact accuracy or performance of downstream programs or data bases. They may only surface after doing considerable damage. The belief that instant failure is the sole risk must be reversed now to avoid business loss and higher renovation costs later. Emphasis is on date testing.
