I initially saw Enterprise Architecture as basically a business practice and therefore this was a bit hard for me to understand. Reading on, I could see that this is more than just business, but business mixed with education and tying into technology. What I quickly learned is that there is a core connection to starting with the end in mind. Basically, in any business and especially being in a school, the mission statement drives the goal setting. Of course, the goals from year to year change as do many other things. I found that EA offered what seemed to be an equation of some sort in aligning goals with the mission statement and the use of technology.
