Weekly Reflection #24 - Conceptual integrity
Each week, I share one insight. One piece of wisdom. One question to reflect on. (and a little Lagniappe)
Insight
I have to come clean. I've been putting off one of the most-recommended books in our field for years: The Mythical Man-Month. I can't believe, after co-hosting Book Overflow for almost two years, we hadn't read this yet. Martin Fowler's recent post finally got me to take the plunge, and boy was I missing out!
My favorite idea in the book is conceptual integrity. Conceptual integrity is the property of a system feeling like it was designed by one mind, even when many hands built it. In an era of agentic AI tooling, it's so easy to dial this one in and lose sight of it. It's far too easy for LLMs to be locally capable but globally incoherent. It makes the architect's role, the keeper of conceptual integrity, more important than ever.
Never vibe the conceptual integrity.
Wisdom
Conceptual integrity is the most important consideration in system design.
