I always worry when a single number metric is developed that it will serve to create additional problems-- are utilities going to use this single number, or will it simply be seen as the first indicator after which the experts can come in and dig into the specifics for why the metric was what it was and determine best action?

No doubt that utilities can collect information from devices supporting their infrastructure today more so than any time in the past. The information can be quite helpful in understanding how well or not so well equipment is functioning. The challenge is to build up a data model that helps them correlate information and move from reactive to proactive maintenance. The work is challenging but the end result should make it worthwhile.
