Information technologies (IT), in the context of this paper, include all computer systems and networks, plant automation systems such as distributed control systems and programmable logic controllers, design drawing databases, procedures databases, and diagnostic monitoring systems. The role of information technology is critical for maintenance optimization because it relies on the ability of the plant personnel to bring all data together in a coherent fashion for optimum analysis and decision-making.

Many smaller companies feel maintenance management software is overkill for their organizations. Nothing could be further from the truth. In reality, even a one-person maintenance department can reap the benefits of maintenance management software. The same benefits realized by the maintenance crew in larger companies are there for smaller maintenance departments also.
