BiSL (Business Information Services Library) is a vendor independent public domain library for the implementation of business information management. 

What is BiSL?

The original BiSL publications largely cover operational guidance and will be of particular relevance to those organisations with little or no BIM capability. The processes are largely based on ITIL guidance from versions one and two and will need to be supplemented with strategic guidance which is line with modern day thinking about DEVOPS and agile working. The operational guidance included in these publications is included in new and forthcoming DID publications.

As a result the forthcoming update to the original BiSL guidance (3rd edition, which comprises minor updates and corrections) will be the last.

BiSL aims to professionalize the demand function. Not only within an organization, but also as a unifying factor between different organizations.

The standardized approach of BiSL contributes to the professionalization of the demand organization and facilitates a more efficient and cost effective way of working.

The BiSL Framework

The BiSL framework gives a description of all the processes that enable the control of information systems from a business perspective.

The framework distinguishes seven process clusters, which are positioned at the operational, managing and strategic levels


In 2005, the Business Information Services Library (BiSL) was launched into the public domain as a library for business information management.

The library consists of publications describing the process framework for business information management and a large number of best practices, white papers, articles and presentations. The library is promoted and supported by the ASL BiSL Foundation.

The adoption of BiSL in the market was quite fast, and it was implemented in many organizations, primarily in the Netherlands. In 2012 a revised version of BiSL was published in which some of the terminology was slightly updated.

From BiSL2 to
BiSL 3

BiSL 3rd edition does not deviate essentially from BiSL second edition (2012). This makes the framework “upwards compatible”. Existing BiSL users will not experience any restrictions, but will be provided with additional options and information.

Multiple topics have been added, such as: chains, data, security, the shift of many custom applications to mainly packages and to Cloud and with that the other role of the IT organization.

A new chapter describes the relationships with various other frameworks and models. In addition, the Operational chain coordination process has been added to the BiSL model and some processes have been rearranged.
