IIBA® was founded in Toronto, Canada in October of 2003 to support the business analysis community by:

  • creating and developing awareness and recognition of the value and contribution of the business analyst,
  • defining the Business Analysis Body of Knowledge® (BABOK® ),
  • providing a forum for knowledge sharing and contribution to the business analysis profession, and
  • publicly recognizing and certifying qualified practitioners through an internationally acknowledged certification program.

The Body of Knowledge Committee was formed in October of 2004 to define and draft a global standard for the practice of business analysis. In January of 2005, IIBA released version 1.0 of A Guide to the Business Analysis Body of Knowledge®  (BABOK® Guide ) for feedback and comment. That version included an outline of the proposed content and some key definitions. Version 1.4 was released in October of 2005, with draft content in some knowledge areas. Version 1.6, which included detailed information regarding most of the knowledge areas, was published in draft form in June of 2006 and updated to incorporate errata in October of 2008.

The Body of Knowledge Committee developed version 2.0 of A Guide to the Business Analysis Body of Knowledge®  (BABOK® Guide ) with the guidance of expert writing teams, and feedback garnered from expert, practitioner, and public reviews. Version 2.0 introduced such concepts as the Requirements Classification Schema and the Input/Output models. Version 2.0 was published in 2009 and became the globally recognized standard for the practice of business analysis.

Following the publication of version 2.0, IIBA sought out a number of recognized experts in business analysis and related fields and solicited their feedback on the content of that edition. The Body of Knowledge Committee used these comments to plan the vision and scope of this revision. The Body of Knowledge Committee worked with teams of expert writers to revise and update the content. The revised draft of A Guide to the Business Analysis Body of Knowledge®  (BABOK® Guide ) was reviewed by teams of both expert and practitioner reviewers. The Body of Knowledge Committee used the feedback provided to further enhance and refine the text and then made the content available to the business analysis community for review in 2014. The thousands of items of feedback from this public review were used to further revise the text to form A Guide to the Business Analysis Body of Knowledge®  (BABOK® Guide ) version 3.0.

The goal of this revision was to:

  • incorporate new concepts and practices in use since the last revision,
  • address the broadening and evolving scope of the profession,
  • incorporate lessons learned from practitioners who have worked with the current version,
  • improve the readability and usability of the guide,
  • improve the consistency and quality of text and illustrations, and
  • improve consistency with other generally accepted standards relating to the practice of business analysis.

The major changes in this release include:

  • the inclusion of the Business Analysis Core Concept Model™ (BACCM™ ),
  • the expanded scope of the role of business analysis in creating better business outcomes,
  • the inclusion of Perspectives which describe specialized ways in which business analysis professionals provide unique value to the enterprise,
  • new and expanded Underlying Competencies to better reflect the diverse skill sets of the business analyst, and
  • new techniques that have emerged in the practice of business analysis.

This publication supersedes A Guide to the Business Analysis Body of Knowledge®  (BABOK® Guide) version 2.0.

The BABOK® Guide  contains a description of generally accepted practices in the field of business analysis. The content included in this release has been verified through reviews by practitioners, surveys of the business analysis community, and consultations with recognized experts in the field. The data available to IIBA demonstrates that the tasks and techniques described in this publication are in use by a majority of business analysis practitioners. As a result, we can have confidence that the tasks and techniques described in the BABOK® Guide  should be applicable in most contexts where business analysis is performed, most of the time.

The BABOK® Guide  should not be construed to mandate that the practices described in this publication should be followed under all circumstances. Any set of practices must be tailored to the specific conditions under which business analysis is being performed. In addition, practices which are not generally accepted by the business analysis community at the time of publication may be equally effective, or more effective, than the practices described in the BABOK® Guide . As such practices become generally accepted, and as data is collected to verify their effectiveness, they will be incorporated into future editions of this publication. IIBA encourages all practitioners of business analysis to be open to new approaches and new ideas, and wishes to encourage innovation in the practice of business analysis.

IIBA would like to extend its thanks and the thanks of the business analysis community to all those who volunteered their time and effort to the development of this revision, as well as those who provided informal feedback to us in other ways.
