It is not just what we train that is at the heart of what we offer, but also who we are. Many of us at Architecting the Enterprise; such as Judith Jones (our CEO-pictured right), Ed Harrington and Serge Thorn- have been key to the development of TOGAF over the years. This is why we take great care to teach and train with quality in mind. It is also why many organisations -including Fortune 500 companies- are loyal, satisfied customers.
Glossary 
Abstraction
The technique of providing summarized or generalized descriptions of detailed and complex content.
Abstraction, as in "level of abstraction", can also mean providing a focus for analysis that is concerned with a consistent and common level of detail or abstraction. Abstraction in this sense is typically used in architecture to allow a consistent level of definition and understanding to be achieved in each area of the architecture in order to support effective communication and decision-making. It is especially useful when dealing with large and complex architectures as it allows relevant issues to be identified before further detail is attempted.
AC
