We are frequently tempted to design our systems' architecture as an expression of the software we think we are going to build. Reality rarely cooperates, though.

Perhaps a better pattern might be to admit to - and enshrine - our ignorance of what we are actually going to build in our architecture, avoiding excessive coupling not only in components, but in our assumptions.

1. Intro - Thesis: instead of pretending certainty, treat ignorance as a first-class design constraint.
2. The Illusion of Certainty (and the cost of premature certainty)
3. Ignorance as a Design Primitive - not incompetence, but *honest admission of what we don’t (and can’t) know yet
4. Patterns of Designing with Ignorance
5. Anti-Patterns
6. Cultural Practices that Support Ignorance
7. Audience Interaction (tell us your story of premature certainty)
8. Closing: Architectures are frameworks for discovery, not monuments to foresight.
