Conclusion

Therefore, Solution Architects:

• Assist in the refinement of business requirements
• Respond to business requirements with feasible technical solutions
• Provide an architectural design for the selected solution that:

• Helps the customer verify that they're satisfied with what they're getting
• Provides a blueprint for the project manager to plan with
• Informs the constructors so that they can estimate cost & effort

• Liaise with:

• The customer to ensure alignment with requirements
• The project manager to identify appropriate constructor engagement
• Constructors to validate feasibility & provide support throughout construction

• Write & present eloquently with the appropriate audience perspective in mind
• Build & maintain excellent relations with key stakeholders
• Apply their creative skills & talents in devising effective designs (a.k.a. thought leadership)
• Continuously expand their knowledge & specialisation of technology & design patterns

I hope that this will generate some interesting discussions either here, as comments, or in the Discussion Forum.
