• Determine the Architecture Capability desired by the organization:

  • Überprüfung des organisatorischen Kontextes für die Durchführung der Unternehmensarchitektur

  • Identifizierung und Abgrenzung der Elemente der Unternehmensorganisation, die von der Architekturfähigkeit betroffen sind

  • Identifizierung der etablierten Frameworks, Methoden und Prozesse, die sich mit der Architekturfähigkeit überschneiden

  • Festlegen des Reifegradziels für die Fähigkeit

• Establish the Architecture Capability:

  • Define and establish

    • the Organizational Model

    • process and resources

  • Select and implement supporting tools

  • Define the architecture principles

• All architecture development needs to start with Phase A

• Not starting with Phase A, practitioners can slide off-course and not deliver useful architecture

1. Define the scope

2. Identify stakeholders, concerns, and associated requirements

3. Assess the capability of the EA team

• Sufficient documentation get permission to proceed

• Permission to proceed to develop a Target Architecture

• The scope of the problem being addressed.

• Those who have interests that are fundamental to the problem being addressed. (Stakeholders & Concerns)

• What summary answer to the problem is acceptable to the stakeholders? (Architecture Vision)

• Stakeholder priority and preference

• What value does the summary answer provide?

• Develop a high-level aspirational vision of the capabilities and business value to be delivered as a result of the proposed enterprise architecture

• Obtain approval for a Statement of Architecture Work that defines a program of works to develop and deploy the architecture outlined in the Architecture Vision

Einholung der Genehmigung für ein Statement of Architecture Work, das ein Arbeitsprogramm zur Entwicklung und Bereitstellung der in der Architekturvision skizzierten Architektur definiert

output:

• A set of domain architectures approved by the stakeholders for the problem being addressed, with a set of gaps, and work to clear the gaps understood by the stakeholders

Essential Knowledge

• How does the current Enterprise fail

• What must be change

• Which Workpaked

• How stakeholder priority and preference adjust in response to value, effort, and risk of change. (Stakeholder Requirements)

• Target Business Architecture

• —> Achive business goals, strateic Drives Architecuter Vision

• Basline between Baseline and Taget Business Architure —> Rodemap

• Target Information Systems

• Target Data Architecture

• Target Application Architecture

• Baseline and Target Information Systems —> Roadmap

• Target Technology Architecture

—> the Architecture Vision, target business, data, and application building blocks

• Baseline and Target Technology Architectures —> Roadmap

Output

• A set of work packages that address the set of gaps, with an indication of value produced and effort required, and dependencies between the work packages to reach the adjusted target

Eine Reihe von Arbeitspaketen, die die Lücken schließen, mit einer Angabe des produzierten Werts und des erforderlichen Aufwands sowie der Abhängigkeiten zwischen den Arbeitspaketen, um das angepasste Ziel zu erreichen

Essential Knowledge

• Dependency between the set of changes

• Value, effort, and risk associated

• stakeholder priority and preference adjust in response to value, effort, and risk of change

• Consolidate the gaps from Phases B to D —> Complete Raodmap

• Transition Architectures to deliver continuous business value

Output & Outcome

• An approved set of projects, containing the objective and any necessary constraints, resources required, and start and finish dates

Essential Knowledge

• Resources available to undertake the change

• How stakeholder priority and preference adjust in response to value, effort, and risk of change. (Stakeholder Requirements)

• FInal Raodmap

• ensure Implementation and Migration Plan is coordinated with the enterprise’s approach

Sicherstellen, dass der Implementierungs- und Migrationsplan mit dem Ansatz des Unternehmens zur Verwaltung und Implementierung von Änderungen im gesamten Änderungsportfolio des Unternehmens koordiniert wird

Anweisung, mit der Entwicklung einer Zielarchitektur zu beginnen, die wahrgenommene, tatsächliche oder erwartete Defizite im Unternehmen in Bezug auf die Präferenzen der Interessengruppen behebt

Essential Knowledge

• Gaps between approved target, or preference, and realization from prior work. (Value Realization)

• Changes in preference or priority. (Stakeholder Requirements)

• architecture development cycle is maintained

• Architecture Governance Framework is executed

• Enterprise Architecture Capability meets current requirements

• Ensure that the Requirements Management process is sustained and operates for all relevant ADM phases

• Manage architecture requirements identified during any execution of the ADM cycle or a phase

• Ensure that relevant architecture requirements are available for use by each phase as the phase is executed

Sicherstellen, dass der Anforderungsmanagementprozess für alle relevanten ADM-Phasen aufrechterhalten wird und funktioniert

Verwaltung der Architekturanforderungen, die während einer beliebigen Ausführung des ADM-Zyklus oder einer Phase ermittelt wurden

• Accourding preferences and priorities of stakeholders

• architecture and the value preference and priority the architecture is expected

Good practitioners:

• Engage in the future of their organisation

• Participate in defining and realising the target state

• Act as Subject Matter Experts (SMEs) – Source of expert advice

• Act as Agents for their stakeholders in developing architecture – may speak on behalf of stakeholder

• Understand when there are acting in a different role and behave appropriately

Build understanding for alter

Identify trade-offs bettwes alter

1. Use the vision priciole and requierments

2. Define alternatives based on the criteria

3. Select one if the alternatives or combine

• Breadth: What is the full extent of the enterprise

• Depth: To what level of detail should the architecting effort go?

• Time Period: What is the time period that needs to be articulated for the Architecture Vision

• Architecture Domains: A complete enterprise architecture description should contain all four architecture domains

• Organizational authority

• Objectives and stakeholder concerns to be addressed

• Availability of people, finance, and other resources
