(
)
Forretningsforankringen, hvorfor skal vi gjøre dette (arkitektur-prosjektet), hvem er våre sponsorer/interessenter, handler om å finne ut verdien av implementert løsning? Hvis ikke fase A virker, bør du ikke fortsette. Strategi er input her. Outlline business case. Risikoanalyse (bruk gjerne andre). Scoping. Relatert til prosjektveiviserens konseptfase. Objective: * Develop a hith-level aspiration vision of the capabilities and business value to be delivered * Obtain approval for a Statement of Architecture Work that defines a program of work to develop and deploy the architecture outlined in the Architecture Vision Approach * Phase A defines what is in and outside of the archtecture effort, and teh constraints * Constrains (føringer, f.eks. loven om offentlig anskaffelser) are informed by principles, business goals and strategic drivers * Creats the Architecture Vision dokument - clarifying and agreeing the purpose of the architecture - demonstrating how it will be achieved - a first-cut high-level description of teh Baseline (nå-tilstand) and Target (mål-) architecture
