QuestionQ53

VerifiedIntroduction to Applying the ADM

You have been appointed as Chief Enterprise Architect (CEA), reporting to the Chief Technical Officer (CTO), of a company that has been established as a separate operating entity by a major automotive manufacturer. The company’s mission is to build a new, industry-leading unified technology and software platform for electric vehicles.

The company uses the TOGAF Standard as the foundation for its Enterprise Architecture (EA) framework, and architecture development follows the purpose-based EA Capability model as described in the TOGAF Series Guide: A Practitioners’ Approach to Developing Enterprise Architecture Following the TOGAF® ADM.

An end-to-end Target Architecture has already been completed, along with a roadmap for change over a five-year period. The new platform will be a cross-functional effort between hardware and software teams, with significant changes compared with the old platform. It is expected to be developed in several stages over three years. The EA team has inherited the architecture for the previous generation hardware and software automotive platform, some of which can be carried forward to the new unified platform. The EA team has begun defining the new platform, including determining which parts of the architecture to carry forward.

Enough of the Business Architecture has been defined so that work can begin on the Information Systems and Technology Architectures. These need to be defined to support the core business services that the company plans to provide. The core services will include an innovative approach with swarm data generated by vehicles, paving the way for autonomous driving in the future.

The presentation and access to different variations of data that the company plans to offer through its platform create an architecture challenge. The application portfolio and supporting infrastructure need to interact with various existing cloud services and data lakes in many countries in order to manage the data at scale.

You have been asked which approach should be used to determine and organize the work required to deliver the requested architectures?

Based on the TOGAF standard, which of the following is the best answer?

Explanation

With an end-to-end Target Architecture and roadmap already in place, the delivery-oriented architecture work should be guided by that superior architecture. It should identify and prioritize projects, dependencies, and synergies; elaborate high-level architecture descriptions; assess reusable reference architectures and candidate building blocks; estimate effort and resource needs against cost and value; and document options, risks, and controls to support stakeholder viability and trade-off analysis.
