(CMM). The ASL framework was developed because ITIL proved inadequate for Application Management. At that time, ITIL lacked specific guidance for application design, development, maintenance and support. Newer ITIL versions, particularly V3, have increasingly addressed the Application Development and Application Management domains; the ASL BiSL Foundation has published a white paper comparing ITIL v3 and ASL.

Purpose

The ASL2 is intended to support Application Management by providing tools. Two main categories of aids are defined: *Descriptions of the processes for Application Management. Plus the use of best-practises *Standard terminology, avoiding the pitfall of talking about different topics while using the same words.


Structure of ASL2

ASL2 contains 3 levels, 6 clusters of processes (3 on the operational level, 1 on the tactical level, 2 on the strategic level) and a totality of 26 processes.


Operational level


Application Support cluster

There are 4 processes within the Application Support cluster. The processes in the Service Organisation cluster support the daily use of the information systems. The processes in this cluster are: * Use Support *
Configuration Management Configuration management (CM) is a process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life. The CM proc ...

IT Operation Management It or IT may refer to: * It (pronoun), in English * Information technology Arts and media Film and television * ''It'' (1927 film), a film starring Clara Bow * '' It! The Terror from Beyond Space'', a 1958 science fiction film * ''It!'' (1967 ...
*
Continuity Management Continuity or continuous may refer to: Mathematics * Continuity (mathematics), the opposing concept to discreteness; common examples include ** Continuous probability distribution or random variable in probability and statistics ** Continuous ...
These processes have as well been defined in the ITIL framework. The processes are similar, but are viewed from another point of view, therefore the activities in each of these processes may differ from the activities in an ITIL-environment.


Application Maintenance Application may refer to: Mathematics and computing * Application software, computer software designed to help the user to perform specific tasks ** Application layer, an abstraction layer that specifies protocols and interface methods used in a c ...
and Renewal cluster

There are 5 processes within the Application Maintenance and Renewal cluster. Within this cluster the majority of the work of Application Development is done. A major part of the work of Application Management deals with designing, programming and testing applications and information systems. Processes are: * Impact analysis *
Design A design is a plan or specification for the construction of an object or system or for the implementation of an activity or process or the result of that plan or specification in the form of a prototype, product, or process. The verb ''to design'' ...
*Realization *
Testing An examination (exam or evaluation) or test is an educational assessment intended to measure a test-taker's knowledge, skill, aptitude, physical fitness, or classification in many other topics (e.g., beliefs). A test may be administered verba ...
*
Implementation Implementation is the realization of an application, or execution of a plan, idea, model, design, specification, standard, algorithm, or policy. Industry-specific definitions Computer science In computer science, an implementation is a realiza ...
These processes are not described at all in the ITIL V1 framework, but do have their counterparts in BiSL, the model for Information management / Functional Management.

es Operational Level cluster

There are 2 processes within the Connecting Processes Operational Level cluster. The connecting processes aim at the synchronisation of the activities between Service Organisation/operations (using the applications) and development and maintenance (changing the applications). The two processes included are: *
Change Management Change management (sometimes abbreviated as CM) is a collective term for all approaches to prepare, support, and help individuals, teams, and organizations in making organizational change. It includes methods that redirect or redefine the use of ...
*
Software Control and Distribution Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists ...


Management level


Management Process Management process is a process of setting goals, planning and/or controlling the organising and leading the execution of any type of activity, such as: * a project (project management process) or * a process ( process management process, somet ...
es cluster

There are 5 processes within the Management Processes cluster. The processes in this cluster are used in the management of the activities within the clusters on the operational level. The processes are located on the tactical level, are used for steering the operational processes. The processes included are: *
Contract Management Contract management or contract administration is the management of contracts made with customers, vendors, partners, or employees. Contract management includes negotiating the terms and conditions in contracts and ensuring compliance with the terms ...
* Planning and Control *
Quality Management Quality management ensures that an organization, product or service consistently functions well. It has four main components: quality planning, quality assurance, quality control and quality improvement. Quality management is focused not only ...
*
Financial Management Financial management is the business function concerned with profitability, expenses, cash and credit, so that the "organization may have the means to carry out its objective as satisfactorily as possible;" the latter often defined as maximizin ...
* Supplier Management


Strategic level


Application Strategy cluster

There are 5 processes within the Application Strategy cluster. Applications live for longer than expected. Systems, functionality, concepts and structure of information systems remain 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, the application management strategies, is created within the cluster Application Strategy. The processes in this cluster are: *IT Developments Strategy *Customer Organizations Strategy *Customer Environment Strategy *Application Life Cycle Management *
Application Portfolio Management IT Application Portfolio Management (APM) is a practice that has emerged in mid to large-size information technology (IT) organizations since the mid-1990s. Application Portfolio Management attempts to use the lessons of financial portfolio manag ...


Application Management Organization Strategy cluster

There are 5 processes within the Application Management Organization Strategy cluster. Also the future of the Application Management organisation, with aspects as skills and capabilities, markets and customers, is very important. Creating the organisation management strategies for this is the aim of Application Management Organization Strategy cluster. Processes in this cluster include: *Account and Market Definition *Capabilities Definition *Technology Definition *Supplier Definition *Service Delivery Definition


ASL2 Maturity Model

There is also ASL2 Maturity Model with 5 levels of process maturity: *Level 1 - Initial *Level 2 - Repeatable *Level 3 - Defined and managed *Level 4 - Optimizing *Level 5 - Chain
