ASL

The Application Services Library (ASL) is a public domain framework of best practices used to standardize processes within Application Management, the discipline of producing and maintaining information systems and applications.
The term "library" is used because ASL is presented as a set of books describing best practices from the IT industry.

ASL is closely related to the frameworks ITIL (for IT Service Management) and BiSL (for Information Management and Functional Management) and to the Capability Maturity Model (CMM).
