The Application Services Library (ASL) is a public domain standard, which describes a standard for processes within Application Management (the discipline of making and maintaining information systems and applications). The public domain comprises the body of all creative works and other knowledge—writing, artwork, music, science, inventions, and others—in which no person or organization has any proprietary interest. ...
The word standard has several meanings: Originally, standard referred to a conspicuous object used as a rallying point in battle. ...
This standard was developed in the Netherlands, and relates to ITIL, BiSL and CMM. It is described in several books and articles, as well as the official website of the ASL Foundation. The Information Technology Infrastructure Library (ITIL) is a customizable framework of best practices that promote quality computing services in the information technology (IT) sector. ...

The ASL is intended to simplify the process of application management by providing tools which fall into two categories:
- Processes for application management and the use of free available best-practises
- Standard terminology for dialogue about application management
The goal of ASL is to enhance and professionalize application management and to provide future-proof information systems and applications.
Structure of ASL
ASL contains six clusters of processes, three on an operational level, one on tactical level and two on a strategical level.
Maintenance Maintenance see repair and maintenance Maintenance is a legal term of art that is used to describe child support and alimony (also called spousal support). ...
There are five processes within the cluster maintenance. Maintenance is the most important cluster, because these processes support the use of the information systems. Processes in this clusters are incident management, continuity management, capacity management, availibilty management and configuration management. The purpose and goals of these processes are similar of these of ITIL, however the way and the subjects are different.
Enhancement an renovation
Within this cluster the majority of the work of application management is done. Most of the work of application management deals with designing, programming and testing applications and information systems. Processes are impact analysis, design, realization, testing and implementation.
The connecting processes synchronise the activities between maintenance (the use of the applications) and the activities changing them. The processes are change management and software control & distribution.
The processes in this cluster manage the activities within the clusters above. Processes are quality management, service level management, cost management and planning & control.
Application Cycle management
Applications exist much longer than expected. Systems, functionality, concepts and structure of information systems remains stable over many years. This knowledge is rarely used. It is important that, while maintaining and enhancing systems, there is a clear view needed what the demands are in the future, and based on that, what and how the future of these applications should look like. This view is created within the cluster application cycle management, with processes like life cycle management, information portfolio management, customer organisation strategy, customer environment strategy and ICT developments strategy.
Organisation Cycle Management
Also the future of the application management organisation, with aspects as skills and capabilities, markets and customers, is very important. Creating a strategy on this future is the aim of Organization Cycle Management, with processes as account definition, market definition, skills definition and service delivery definition
