Architecture Development

Question 1 of 12

GlobalTrust, a mid-sized retail bank, has just had its Architecture Vision and Statement of Architecture Work signed off by the Architecture Board for an omni-channel customer-service model spanning branch, mobile, and contact-centre. You are the Lead Architect opening Phase B (Business Architecture). The contact-centre director, worried her team's processes will be disrupted, is pressing you to publish a concrete roadmap of changes quickly so she can plan. Meanwhile two of your modellers have already begun sketching target-state business-service diagrams straight from the vision deck, without reference to the agreed business drivers or the Architecture Repository. You must set the first activity of Phase B.

Based on the TOGAF standard, which of the following is the best way to begin Phase B?

To de-risk delivery early, first agree the implementation technology stack and physical infrastructure standards the new model will run on, so Business Architecture modelling has a fixed platform to design against.Develop the Target Business Architecture in full detail first, then construct the Baseline only where a gap is later discovered, skipping reference-model selection to save time.Select the Business Architecture reference models, viewpoints, and tools from the Architecture Repository on the basis of the business drivers and stakeholder concerns, then develop Baseline and Target Business Architecture descriptions and perform gap analysis.Jump straight to defining candidate Architecture Roadmap components so Opportunities & Solutions has material to consolidate.
