Bob Hablutzel: Enterprise Archiecture practitioners view a solid EA as critical to setting a three-to-five year strategic plan for the company. I don't see that view as frequently at the business leadership level. As EA practitioners, we need to be able to articulate how and why EA is important. Any kind of long-range planning follows a basic pattern: Purpose, Vision, Strategy, Objective, Plan. The Purpose is why the company exists. In the US, that's frequently "to maximize shareholder value". The Vision is how the company intends to get there - this defines the scope of the business activies that the company will engage it. Purpose and Vision don't change much on a year-to-year basis.
