Outsourcing firms, it appears. While internal staff are responsible for about three quarters of Y2K remediation, contractors also have a large piece of the project at most companies. Among the six industry segments studied, telecommunications companies are the most reliant on contractors, while noncomputer manufacturers are the least likely to use outsiders. Looked at by industry, those in banking and finance showed the most interest in patching. Those in noncomputer manufacturing and utilities are the most likely to opt for replacing existing systems.
Larger companies do more patching than smaller ones.
The general public thinks Y2K problems occur only when the calendar hits 2000, but the IT industry knows better. Whether or not IT shops have experienced a millennium glitch seems to affect how IT managers go about resolving issues. Among those who've run into problems already, there's no clear preference for patching or replacing existing systems.
