Application Maintenance consists of the activities to keep an application and its documentation in conformance to existing business and operational requirements. The Application Maintenance does not change (add, modify, or delete) the business functionality provided by the application to the user.
Adaptive Maintenance is that portion of Application Maintenance to modify an application and its documentation as necessitated by changes (patches, updates, etc) to the technical environment in which the application operates. Modifications are not made for the purpose of changing user functionality. Each Adaptive Maintenance Request for Change will be estimated as a whole and will not be divided into requests of lesser size.
