Event Engineering — Part VI: Institutional Memory and Event Engineering — From Distributed Experience to Carried Structural Knowledge

Abstract

Part III of Event Engineering showed that structure can be extracted from repeated experience through comparison, but left unexamined a question its own central illustration — the unfolding model of voluntary employee turnover, built from interviews with many different departing nurses — makes unavoidable: repetition need not belong to a single continuous actor. When the experiences that reveal a structural relation are distributed across different individuals, no one person carries the sequence of experiences from which the structure was extracted. Part VI addresses the resulting problem directly: where does extracted structure reside once the individuals who lived the originating experiences are no longer present, and once the act of comparing and extracting that structure may itself have been performed by yet another actor? The paper develops a three-role distinction — experiencer, extractor, and carrier — that may coincide in a single actor or separate across several, and argues that what survives this separation is never the original experience, and not necessarily the extractor's full reasoning, but a structural representation: a condensed account of what recurred across otherwise dissimilar experiences. The central discipline this requires is kept sharply bounded: extraction introduces a selection of representation, but this is not, by itself, appropriation in the sense developed in Part V; appropriation begins only if that representation is later treated as a determination of a future execution that belongs to a different actor. A case study drawn from clinical practice guidelines — evidence gathered from distributed patients, synthesized by guideline committees, and carried by clinicians who treat future patients they had no part in studying — makes this separation of roles, and the risk of its collapse into rigid prescription long documented in the medical literature as "cookbook medicine," concretely visible. Part VI closes by stating the discipline that institutional memory must observe if it is to feed Event Engineering without pre-empting it: institutional memory preserves extracted structure; it does not prescribe future execution. The central theses are therefore: "If no single actor carries the sequence of experiences from which a structure was extracted, where does that structure reside between one event and the next?" "Structural representation is not future execution." "Institutional memory preserves extracted structure without prescribing future execution."
