Overview

(Chapter 1 of Solutions Architecture Best Practices and Framework)

Executive Summary: Chapter Overview

IF4IT

The Bottom Line

This document establishes Solutions Architecture as a repeatable, governed professional discipline: a documented framework (the Solutions Architecture Framework) for arriving at comprehensive, well-documented answers to specific problems (a Solutions Architecture, or Solution Set), and a governed artifact (the Solutions Architecture Reference Book) for capturing how that answer was reached.

Core Concepts

Concept	Definition & Strategic Role
Solutions Architecture	Two related senses covered throughout this document: the professional practice that reliably produces answers to problems, and the Solution Set — the actual answer itself — that practice produces for a given problem, one specific engagement at a time.
The Solutions Architecture Framework (SAF)	The five-phase, repeatable methodology this document standardizes for practicing Solutions Architecture, scaling to problems of any size and drawing on already-proven consulting and engineering practice rather than inventing something new.
The Solutions Architecture Reference Book (SARB)	The governed, per-engagement artifact that documents how a Solutions Architecture was reached — the problem, the options considered, and every decision made, delivered to the Customer and stored for future engagements to draw on.

Quick Q&A

Question: Who should read this document?

Answer: Solutions Architects, Application and Technology Architects, Enterprise Architects, and the IT and Business leaders who sponsor, govern, or depend on Solutions Architecture engagements, as well as the Engineers and Developers who build against the Solution Sets those engagements ultimately produce and deliver.

Question: How is this document organized?

Answer: Four subsections: what Solutions Architecture is and how it relates to other architecture practices and to Enterprise Architecture; the Solutions Architecture Framework itself, including the SARB used to document it; how Solutions Architecture correlates with other IT Management disciplines; and closing guidance that ties the whole document together.

Who This Document Is For

This document is written for Solutions Architects and the specialized architecture practices they draw on — Business Architects, Data & Information Architects, Technical/Technology Architects (including Application Architects), and Security Architects — as well as for the IT and Business leaders who sponsor Solutions Architecture engagements, the Engineers and Developers who build against the Solution Sets those engagements produce, and the Enterprise Architects whose Enterprise Architecture practice both feeds and is fed by Solutions Architecture work.

What This Document Covers

This document is organized into four subsections. “Understanding What Solutions Architecture Is” defines Solutions Architecture itself, distinguishes it from the other specialized architecture practices it draws on, and establishes its relationship to Enterprise Architecture. “The IF4IT Solutions Architecture Framework” presents the repeatable, five-phase methodology this document standardizes, the SA Dimensions a comprehensive solution must account for, and the Solutions Architecture Reference Book used to document the work. “Correlating Solutions Architecture With Other Disciplines” correlates Solutions Architecture with adjacent IF4IT disciplines. “Closing and Additional Resources” closes out the document.

How to Use This Document

Readers new to Solutions Architecture should read the first two subsections in order: they establish the terminology and the framework that the rest of the document depends on. Practicing Solutions Architects can use later subsections as a standing reference during an actual engagement, returning to the SAF phase chapters and the SARB chapter as each phase of a real engagement is underway.
