An Architecting Book of Knowledge (BoK) to Improve Architectural Decision-Making

Abstract

To advance architecting from its current heuristics-based mode to a principles-based mode, this paper presents a systematic approach to architectural decision-making within the framework of a Book of Knowledge (BoK) and highlights how such decisions can shape complex systems over time. It emphasizes the need for a community-driven database of architectural knowledge, where best practices, patterns, and insights from past decisions can inform future work. Using a structured approach, the document outlines the Comprehensive Architecture Strategy (CAS), which aids architects in documenting and analyzing key elements such as patterns, ilities, and rules that govern architectural decisions. By breaking down architectural processes into well-defined components, CAS provides a standardized way to assess the impact of design choices on system ilities, supporting informed decision-making and enabling consistency across architectural projects.
