### Overview Significant risks to the project can be mitigated by creating an architectural proof of concept. It is important to address risk as early as possible in the project so key strategic and architectural decisions can be made while it is still easy to modify fundamental pieces of the architecture. Creating early proofs of concepts reduces overall project risk and unknowns. Lower project risk and fewer unknowns makes planning and estimating in later iterations more accurate. Proofs of concepts can be temporary, discarded once the issues have been addressed, or built as the foundation of the core architecture. # Entry Criteria Application Diagram Used to implement proof of concept. Deployment Diagram Used to establish logical order of deployment. System Diagram Used to configure proof of concept. Logical Datacenter Diagram Used to configure the environment to test proof of concept. When: Deployment diagram validates against logical datacenter diagram for a system. # Sub-Activities
1 | Examine Risk | Understand the elements that lead to the identification of the risk or architectural decisions. Examine related scenarios and quality of service requirements. Check on any target environment implications.
2 | Plan the Approach | Determine the form of proof of concept needed. Use the application and system diagrams to assist in planning. Solve only the architectural problem identified by the risk. Look for the simplest resolution.
3 | Build and Run the Proof of Concept | Build the proof of concept. You can implement the proof of concept from the application diagram. Maintain focus on the problem to be solved. Deploy the proof of concept to a physical environment congruent to the logical datacenter diagram. The physical environment should match the settings of the logical datacenter diagram as closely as possible. Test the proof of concept against the high-risk issues.
# Exit Criteria
| A proof of concept is built and examined for each architectural approach.
