“Sufficiently” is doing deliberate work in this definition: a shared reference is not uniformity. Two managers can disagree about a decision and still share a reference — as long as they agree on what the decision is about, what would count as success, and who may take it. The reference fails earlier and more quietly: when the disagreement itself becomes invisible, because each side is answering a different question without knowing it.
Shared references are maintained, not built once. They are renewed in slow moments — joint reviews, repeated questions, conversations that look redundant — and those are the first moments cut when an organization optimizes for speed. What follows is reference drift.
Where this comes from. This term is defined in the glossary of The Hidden Cost of Speed by Christoph Svoboda. About the book.
