Develop broad expertise in business and IT, communicate with stakeholders, collaborate in teams, innovate, and apply systems thinking to design enterprise architecture artifacts.
Explore five archetypes of architects in enterprise architecture—solution, domain, business unit, enterprise architects, and architecture managers—covering organizational scopes, domains, and their integration across strategy, technology optimization, and delivery.
Understand the hierarchy of architecture positions from specialists to generalists, detailing solution, domain, business unit, and enterprise architects with their scope, domain expertise, and artifacts such as outlines and designs.
Map organization as a domains-by-units matrix, showing enterprise architects across matrix, domain architects and business unit architects across rows and columns, and solution architects in cells, with architecture managers coordinating.
Map architecture positions to enterprise architecture processes, clarifying roles of enterprise, business unit, domain, and enabling domain architects with solution architects in strategic planning, initiative delivery, and technology optimization.
The architecture function acts as the interface between business leaders and the IT department, translating ideas into designs and artifacts to enable enterprise information systems planning.
Examine how architecture functions scale with organizational size and decentralization, detailing domain, business unit, and solution architects, and outlining centralized and decentralized operating models.
Navigate governance bodies of architecture functions, including strategic, technology, investment, and design committees. See how artifacts gain endorsements, how decisions escalate, and how governance scales with organization size.
Explore modeling languages for enterprise architecture—Archimate, UML, BPM, and Eris—and their roles, limitations, and applicability to visions, landscapes, outlines, and designs, focusing on communication over formalism.
Explore how enterprise architecture tools store, visualize, and analyze the landscape, compare cmdbs and architecture tools, and decide when to use office tools alongside a tool portfolio.
Leverage strawman architecture as informal, lightweight sketches to spark early stakeholder discussions and convert them into formal artifacts through governance, avoiding unfeasible options.
Explore architecture debt in enterprise architecture, distinguishing tactical shortcuts from strategic goals, and learn how debt registers, governance, and technology optimization reveal and repay delayed costs.
Evaluate investment quality and technical deviations in enterprise architecture using quantitative indicators, mapping investments to business capability models, to steer strategic decisions and improve alignment.
Adapt architecture language to business audiences, present simple artefacts with clear value, and introduce artefacts gradually to foster organizational acceptance of the enterprise architecture practice.
Develop a mature enterprise architecture practice by aligning artifacts and processes with organizational needs, fostering business–IT collaboration, and strengthening management quality for sustainable competitive advantage.
internal architecture teams own information systems planning, while external consultants contribute via initiative-based, strategic, and developmental engagements that emphasize knowledge transfer over documents.
Part III of the course The Practice of Enterprise Architecture provides a high-level discussion of other important aspects of enterprise architecture and an EA practice. This part addresses diverse secondary facets of an EA practice omitted in the previous sections including architects, architecture functions, architecture governance, EA tools and modeling languages, EA-related measurements, initiation and maturity of an EA practice as well as the relationship between an internal EA practice and EA consulting.
Part III consists of four consecutive sections:
Section 16 (Architects in Enterprise Architecture Practice) discusses the role and skills of architects, common architecture positions often found in organizations, their differences and relationship
Section 17 (Architecture Functions in Organizations) discusses the general role and structure of architecture functions in organizations as well as the roles and different types of architecture governance bodies
Section 18 (Instruments for Enterprise Architecture) discusses specialized modeling languages and software tools for enterprise architecture, templates for EA artifacts, architecture debt and quantitative measurements for an EA practice
Section 19 (The Lifecycle of Enterprise Architecture Practice) discusses the initiation of an EA practice in organizations, maturity of an EA practice and the role of external consultancies in an EA practice
