Enterprise architecture is like Generation X thing for so many of IT professionals now. Enterprise Architecture was conceptualized and developed to reality by Generation X. They believed in it, they practiced it. Generation Y and Z are not the same people, they grew up with Digital Media, Rule following just because someone said so is not their thing. They need to use it believe it, there is no concept of “x years of planning”, the strategy does not mean anything unless it uses the cool prospect of technology.

Generation Y and Z are growing up with faster than instant. The application is NOT the concept they embrace, they worked with Services and furthermore microservices. The Penn State class taught me the history of Enterprise Architecture, how it has been done so far for large dinosaur sized organizations. I am not sure unless it is re-invented to suit new generation, appeal the growing generation of professionals, I believe the Traditional EA will die and will be responsible for its own demise.
