Emerging professions need to define their role and contributions to business and society. An important part of this is setting policies and definitions of what constitutes a professional and professional practice in their discipline. This information is increasingly being captured and codified using tools such as Bodies of Knowledge, Quality Frameworks and Codes of Practice. The International Institute for Business Analysis defined a Body of Knowledge for Business Analysis (BABOK). This paper reports on a longitudinal survey of 240 SEEK advertisements over a six year period investigating how closely the skills and knowledge required for Business Analysis positions matched those defined within BABOK. This exploratory and qualitative study used secondary sources, so generalizability of results has limitations. Nevertheless, interesting patterns were observed. There was strong evidence that the “Competencies” defined within BABOK are sought by employers. However, surprisingly little reference was made to many of the BABOK Knowledge Areas.
