Craft an architectural vision in phase A by applying business scenarios to define business requirements and value outcomes for the baseline and target architecture, with smart, time-bound outcomes.

Identify stakeholders and extract business requirements, document them in the architecture requirements specification and repository, and define measurable success criteria, constraints, assumptions, and service contracts across ADM phases.

Clarify business principles, goals, and drivers to provide context for your architecture work. Use the TOGAF template to capture these elements and guide phase A architecture vision and later phases.

Evaluate capabilities across enterprise, IT function, and architecture function to assess baseline and target maturity, gaps, and readiness for business transformation readiness assessment, using TOGAF phase A guidance and templates.

Evaluate readiness factors for business transformation during phase A architecture vision using the TOGAF ADM, presenting them with maturity models and outlining risks and mitigation actions.

Define the architecture vision in phase A as a high-level, aspirational view of capabilities and business value, guiding stakeholders and shaping target architectures across business, data, application, and technology.

Define the statement of architecture work in TOGAF 10 during phase A architectural vision to document findings, scope, and approach for the architecture project.

Define the architecture vision from the architecture work request, scope the project, and build consensus with sponsors using the statement of architecture work to proceed.

Develop the target business architecture to support an agreed architecture vision, align data, application, and technology architectures, manage value and risk, and address gaps with work packages.

Perform a gap analysis between baseline and target business architectures, develop the as-is and target architectures with selected reference models and tools, and validate with stakeholders to define the roadmap.

Apply gap analysis within TOGAF ADM to identify gaps between baseline and target architectures across business, data, application, and technology using ABS-SBS matrix and mark included, eliminated, or new.

Identify and validate the business architecture as the first activity. Demonstrate value and ROI to stakeholders and enable data and technology architecture.

Develop the target data and application architectures to support the business architecture and architecture vision, and identify candidate roadmap components to close gaps, generating data models and interface diagrams.

Understand that the steps in phase c information systems architectures mirror those in phases b and d, and revisit phase b for a refresher.

Learn to describe baseline and target application architecture using TOGAF artifacts such as the application portfolio catalog, organization matrix, and communication diagram, balancing logical and physical components for stakeholders.

Explore data architecture artifacts, including the data entity business function matrix and the logical data diagram, to define data ownership and the relationships among entities for developers and designers.

Conclude phase C by applying approaches for application and data architectures using models and reference models; emphasize data management, migration, governance, and data at rest, in motion, or in use.

Develop the target technology architecture to enable the architecture vision and the data and application building blocks, and identify roadmap components from gaps between baseline and target architectures.
