This document provides a template for a Transition Architecture for Project XXXX for Client YYYY. The Transition Architecture will define the enterprise architecture at incremental transition states between the baseline and target architectures. It will include an opportunity portfolio with gaps, solutions and dependencies. A work package portfolio will define individual work packages. Milestone transition architectures will define the business, data, application and technology architectures at different transition states. Implementation factors like risks, issues, assumptions and dependencies will be assessed. Architecture gaps and potential solutions will be consolidated.

3. 1 Purpose of this Document
A Transition Architecture shows the enterprise at incremental states reflecting periods of transition that sit
between the Baseline and Target Architectures. Transition Architectures are used to allow for individual
work packages and projects to be grouped into managed portfolios and programs, illustrating the business
value at each stage.
