installed software inventory

If too many applications are assigned to installed software inventory, the Mission-Critical Data class will dampen, and possibly even negate, the value of having a separate class (from Transactional Data). For example, if 10 applications are assigned as Transactional Data (because of their interactive, foreground networking characteristics) and all 10 are determined to be classified as Mission-Critical Data, the whole point of a separate class for these applications becomes moot. However, if only one or two of the Transactional Data applications are assigned to the Mission-Critical Data class, the class will prove highly effective

Related to this point, it is recommended always to seek executive endorsement of the QoS objectives before design and deployment. By its very nature, QoS is a system of managed unfairness and, as such, almost always creates political and organizational repercussions when implemented. To minimize the effects of such nontechnical obstacles to deployment, which could prevent the QoS implementation altogether, it is recommended to address these political and organizational issues as early as possible and to solicit executive installed software inventory endorsement whenever possible
