The Guideline

1. Select program or project to start (low risk) supported by
C-Level
2. Establish Virtual Team maintain standard architecture
development method
3. Acquire and Maintain Knowledge of Enterprise
Architecture Development with change and feed back
communication system
4. Create architecture reference based on current
deployments
5. Develop new architecture layered model from current
deployment with business alignment and operation life
cycle consideration
6. Replicate to new program or project development
