Systems and methods for assessing application usage
View Patent ↗Various of the disclosed embodiments disclose systems and methods for assessing usage of a resource, such as hardware, software, or firmware, in a computer system. For example, some embodiments contemplate a model in which an enterprise application derives its license cost based upon the actual business value provided by the licensed resource to the enterprise. If an enterprise has purchased software that it uses very heavily, then the license cost may increase. Conversely, if the enterprise uses the software rarely, then the license cost may decrease. This usage granularity may allow an enterprise executive to purchase a software license without fear that the software will be inefficiently utilized. A licensor may similarly use the system to charge more accurate fees.
