Executive Decision Support
The Questions Executives Actually Ask
Most EA content explains what frameworks are. Executives want to know what to fund, what to stop, and how to reduce risk without slowing delivery. These answers are written for that moment.
- How much does Enterprise Architecture cost?
- Do we need an Enterprise Architect?
- What EA tool should we buy?
- How do you justify EA ROI?
- Why do EA programs fail?
- How do CIOs use Enterprise Architecture?
Comprehensive Architecture Guides
Long-form guides written from practice: how to structure the work, what artifacts matter, where governance helps (and where it hurts), and how to make trade-offs with executives in the room.
Application Modernization Strategy Guide
Application modernization prioritizes retire, replace, replatform, and refactor based on value and risk. Build factories, patterns, and funding models that scale.
Architecture Governance That Actually Works
Effective architecture governance accelerates decisions, reduces risk, and earns stakeholder trust. Design ARBs, standards enforcement, and metrics that work in practice.
Architecture Principles: Design & Adoption
Architecture principles guide decisions when details are uncertain. Design memorable principles, enforce through funding, and measure adoption—not poster slogans.
Architecture Review Board (ARB) Operating Guide
Run an ARB that decides quickly, enforces standards fairly, and earns respect from delivery teams. Templates, cadence, and metrics included.
Business Architecture: From Strategy to Execution
Business architecture translates strategy into capabilities, value streams, and investments IT can execute. Learn BIZBOK-aligned methods, heatmaps, and operating cadences that engage executives.
Six Architecture Domains
Use domains to assign accountability and produce the minimum set of artifacts that keeps strategy, delivery, and operations aligned.
Business Architecture
Capabilities, value streams, operating models
Application Architecture
Portfolio rationalization and roadmaps
Data Architecture
Domains, governance, and strategy
Technology Architecture
Platforms, standards, and cloud
Security Architecture
Zero trust, controls, and compliance
Solution Architecture
Bridging strategy and delivery
