Management by Exception is actually an old idea and it is used for the Business Process management and even for the Accounting as defined in the following website that I have recently found: http://www.allbusiness.com/glossaries/management-by-exception/4944378-1.html
Wikipedia, referring to the same source, defines Management by Exception as a
"policy by which management devotes its time to investigating only those situations in which actual results differ significantly from planned results. The idea is that management should spend its valuable time concentrating on the more important items (such as shaping the company's future strategic course). Attention is given only to material deviations requiring investigation."
I would say if one applies this definition to IT, it turns to my term "System Management by Exception" where the "management" is Capacity management analysts or Capacity planners and "material deviations" are servers or applications' exceptions.
Speaking about applications' exceptions, currently I am working on applying “Management by Exception” approach not to servers farm capacity management (I think I have already done this successfully) but to a set of applications to produce automatically the list of only those applications that are having some exceptions (unusual but not yet deadly behavior) to help providing proactive application capacity/performance management. Why? Because in some IT environments with large number of applications the centralized capacity management does not exist and application support teams have to play that role and SEDS (System Management by Exception tool) should deliver automatically them what systems need attention within each exceptional application.
