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).
The ASL framework was developed because ITIL proved inadequate for Application Management.[ citation needed ] 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. [1]
ASL was developed in the late nineties in the Netherlands, originally as the proprietary R2C model, which evolved into ASL in 2000. In 2001 it was donated by the IT Service Provider PinkRoccade to the ASL Foundation, now the ASL BiSL Foundation. The version ASL2 was published in 2009.
The ASL2 is intended to support Application Management by providing tools. Two main categories of aids are defined:
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.
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:
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.
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:
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.
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:
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:
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:
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:
There is also ASL2 Maturity Model with 5 levels of process maturity:
Configuration management (CM) is a systems engineering 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 process is widely used by military engineering organizations to manage changes throughout the system lifecycle of complex systems, such as weapon systems, military vehicles, and information systems. Outside the military, the CM process is also used with IT service management as defined by ITIL, and with other domain models in the civil engineering and other industrial engineering segments such as roads, bridges, canals, dams, and buildings.
A value chain is a set of activities that a firm operating in a specific industry performs in order to deliver a valuable product to the end customer. The concept comes through business management and was first described by Michael Porter in his 1985 best-seller, Competitive Advantage: Creating and Sustaining Superior Performance.
The idea of the value chain is based on the process view of organizations, the idea of seeing a manufacturing organization as a system, made up of subsystems each with inputs, transformation processes and outputs. Inputs, transformation processes, and outputs involve the acquisition and consumption of resources – money, labour, materials, equipment, buildings, land, administration and management. How value chain activities are carried out determines costs and affects profits.
In systems engineering, information systems and software engineering, the systems development life cycle (SDLC), also referred to as the application development life-cycle, is a process for planning, creating, testing, and deploying an information system. The systems development life cycle concept applies to a range of hardware and software configurations, as a system can be composed of hardware only, software only, or a combination of both. There are usually six stages in this cycle: requirement analysis, design, development and testing, implementation, documentation, and evaluation.
Information technology (IT) governance is a subset discipline of corporate governance, focused on information technology (IT) and its performance and risk management. The interest in IT governance is due to the ongoing need within organizations to focus value creation efforts on an organization's strategic objectives and to better manage the performance of those responsible for creating this value in the best interest of all stakeholders. It has evolved from The Principles of Scientific Management, Total Quality Management and ISO 9001 Quality management system.
Information technology service management (ITSM) are the activities that are performed by an organization to design, build, deliver, operate and control information technology (IT) services offered to customers.
The Information Services Procurement Library (ISPL) is a best practice library for the management of Information Technology related acquisition processes. It helps both the customer and supplier organization to achieve the desired quality using the corresponded amount of time and money by providing methods and best practices for risk management, contract management, and planning. ISPL focuses on the relationship between the customer and supplier organization: It helps constructing the request for proposal, it helps constructing the contract and delivery plan according to the project situation and risks, and it helps monitoring the delivery phase. ISPL is a unique Information Technology method because where most other Information Technology methods and frameworks focus on development, ISPL focuses purely on the procurement of information services. The target audience for ISPL consists of procurement managers, acquisition managers, programme managers, contract managers, facilities managers, service level managers, and project managers in the IT area. Because of ISPL's focus on procurement it is very suitable to be used with ITIL and PRINCE2.
COBIT is a framework created by ISACA for information technology (IT) management and IT governance.
ITIL security management describes the structured fitting of security into an organization. ITIL security management is based on the ISO 27001 standard. "ISO/IEC 27001:2005 covers all types of organizations. ISO/IEC 27001:2005 specifies the requirements for establishing, implementing, operating, monitoring, reviewing, maintaining and improving a documented Information Security Management System within the context of the organization's overall business risks. It specifies requirements for the implementation of security controls customized to the needs of individual organizations or parts thereof. ISO/IEC 27001:2005 is designed to ensure the selection of adequate and proportionate security controls that protect information assets and give confidence to interested parties."
IT portfolio management is the application of systematic management to the investments, projects and activities of enterprise Information Technology (IT) departments. Examples of IT portfolios would be planned initiatives, projects, and ongoing IT services. The promise of IT portfolio management is the quantification of previously informal IT efforts, enabling measurement and objective evaluation of investment scenarios.
Financial Management for IT Services is a Service Strategy element of the ITIL best practice framework. The aim of this ITIL process area is to give accurate and cost effective stewardship of IT assets and resources used in providing IT Services. It is used to plan, control and recover costs expended in providing the IT Services negotiated and agreed to in a service-level agreement (SLA).
Performance engineering encompasses the techniques applied during a systems development life cycle to ensure the non-functional requirements for performance will be met. It may be alternatively referred to as systems performance engineering within systems engineering, and software performance engineering or application performance engineering within software engineering.
Frameworx is an enterprise architecture framework geared towards communications service providers.
An operating model is both an abstract and visual representation (model) of how an organization delivers value to its customers or beneficiaries as well as how an organization actually runs itself.
Business Information Services Library (BiSL), previously known as Business Information Service Management Library, is a framework used for information management.
Lean IT is the extension of lean manufacturing and lean services principles to the development and management of information technology (IT) products and services. Its central concern, applied in the context of IT, is the elimination of waste, where waste is work that adds no value to a product or service.
GQM+Strategies is a method that provides concepts and actionable steps for creating the link between goals and strategies across an organization and allows for measurement-based decision-making. It was developed by Victor Basili, Jens Heidrich, Mikael Lindvall, Jürgen Münch, Myrna Regardie, Carolyn B. Seaman, and Adam Trendowicz. The method was originally developed for organizations having a strong focus on IT and the development of software systems, but the method's popularity has grown to other domains and can be applied to any organization. The book Aligning Organizations through Measurement gives a comprehensive overview of the method, provides actionable guidance, case studies, and practical applications.
Tudor IT Process Assessment (TIPA®) is a methodological framework for process assessment. Its first version was published in 2003 by the Public Research Centre Henri Tudor based in Luxembourg. TIPA is now a registered trademark of the Luxembourg Institute of Science and Technology (LIST). TIPA offers a structured approach to determine process capability compared to recognized best practices. TIPA also supports process improvement by providing a gap analysis and proposing improvement recommendations.
The Service Design Package (SDP) contains the core documentation of a service and is attached to its entry in the ITIL Service Portfolio.
The Service Portfolio is described in the ITIL books Service Strategy and Service Design. The Service Portfolio is the core repository for all information for all services in an organization. Each service is listed along with its current status and history. The main descriptor in the Service Portfolio is the Service Design Package (SDP).
The Information Technology Infrastructure Library (ITIL) is a set of detailed practices for IT activities such as IT service management (ITSM) and IT asset management (ITAM) that focus on aligning IT services with the needs of business.
