ASL (Application Services Library) is defined as a public domain framework for the management, maintenance and enhancements for business applications.
The ASL framework defines 26 processes, which are categorized across Operations, Management and Strategic platforms. There is a further breakdown for a large number of the processes into sub-categories.
The sub-categories for ASL are (a) organizational cycle management, (b) applications cycle management, (c) maintenance & control & (d) enhancement & renovation.
The number 26 is coincidentally the number of processes that are defined in ITIL v3. Many of the process names from ASL are identical to ITIL v3.
