INTRODUCTION

English translation pending.

CORE DEFINITION

Return to fundamentals means addressing the origin of a problem rather than repairing its downstream manifestations. The core proposition is that a problem which keeps returning is being handled at the end of the chain, where each fix addresses an instance rather than the mechanism producing the instances. The key qualification is that root causes can be upstream and costly to change, so the search must be justified by the recurrence rate: a one-off failure does not warrant rebuilding the source.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Recurrence check: ask how many times this problem has already been fixed downstream. - Upstream trace: follow the causal chain back until you reach the mechanism producing the instances. - Source fix: correct that mechanism and then verify that downstream incidents stop.

Anchor fast decisions

A mechanism at the source generates instances continuously, so any intervention downstream faces a supply of new cases. Correcting the source removes the supply, which is why a single upstream change can replace an indefinite series of downstream repairs. The difficulty is that the source is usually less visible and involves more people than the symptom.
