IASA developed a series of EA certification training programs based on the Business Technology Architecture Book of Knowledge (BTABoK) competency model to assist organizations in developing a comprehensive capability and competency development plan to equip people within the organization with the necessary skills, knowledge, attitude, experiences, and qualifications to perform all necessary tasks.

The BTABoK was founded with the goal of creating a world-class architecture practice, and these goals are reflected in its five pillars: Business Technology Strategy, Design, Human Dynamics, Quality Attributes, and Information Technology Environment to map with five specialization areas: business, information, infrastructure, software, and solution to enhance the professional career path in EA. The ultimate goal of the competency model is helping to ensure that individual architects are prepared to do the job at the correct level and are able to grow their competencies. However as each of the pillars has numerous competencies and architects often grow different competencies at different rates, the BTABoK uses a total average for the pillar to determine the individual’s overall professional level.
