Introduction:
Purpose of this Document
This playbook is a practical guide for designing, selecting, and presenting architectural diagrams across project engagements. It provides a standardized, repeatable framework to ensure architecture teams deliver consistent, high-impact designs that bridge the gap between complex IT infrastructure and the core business problems they are meant to solve.
The Guiding Principle of Architectural Design
Diagrams are not just technical illustrations; they are targeted communication tools. A diagram is only successful if it speaks the language of its intended audience. An infrastructure blueprint, mapping nested container environments is useless to a financial sponsor, just as a high-level business capability map is useless to a firewall engineer.
This playbook empowers architects to select the right diagram, for the right audience, at the right time. It clearly defines what each diagram illustrates, the primary stakeholders it serves, when it is should be used, and equally importantly when to leave it out to avoid overcomplicating the design.
About the Architecture Examples (Project Horizon)
All architecture diagrams created in this playbook were created using Archi, which is an open-source ArchiMate modeling toolkit.
To demonstrate the full breadth of these architectural frameworks without compromising Operational Security (OpSec) or violating Intellectual Property (IP) agreements, Project Horizon is a completely fictitious scenario. This fictitious scenario allows me to fully illustrate the flow of enterprise design from business capability down to network implementation.
