Pragmatic Enterprise ArchitectureUnneccesary EA Steps

If you want to build a new addition to your house or even scrap your house and build a new one on the old foundation, you don’t need a complete blueprint of the existing house.

Exhaustively define “Current State” Architecture
Exhaustively define “Future State” Architecture

Business strategies, vendor products and technologies change, therefore you need to “architect for change” and keep your options open.
Create roadmaps on a “just in time” basis as you launch specific EA initiatives and architect enterprise solutions. Define “just enough” of the current and future states to implement your transformations and solutions.

Exhaustively define Roadmap to “Future State” Architecture

Open Space WorkshopThe Laws of Open Space
Respect for others
Whoever comes is the right people
Whatever happens is the only thing that could have
Whenever it starts is the right time
When it's over it's over
The law of two feet
