DESCRIPTION
So, you are an architect. What does this mean? How do you define yourself? Iasa has worked with more than 7,000 architects to create a common definition and understanding of IT Architecture as expressed by five pillars: Business Technology Strategy; Human Dynamics; Quality Attributes; IT Environment; and Design, and to create a common vocabulary to be shared amongst all IT Architects. Iasa has further defined IT Architecture as a profession backed by various levels of certification. This session discussed Iasa's Architectural Foundations material, offering a clear understanding of what IT Architecture is, and who IT Architects are. Watch, learn and validate what 30,000 architects worldwide are now sharing.
