Management by Exception

 This post introduces a conceptual model for Management by Exception, reframed through the lens of distribution analysis. By distinguishing between expected and excessive distribution, the framework enables organizations to focus attention and resources on deviations that matter. It supports efficient monitoring, risk mitigation, and adaptive control across operational systems.


Management by Exception
Modeling Based on 後正武 『意思決定の​ための​分析の​技術』

Entity Name Description
Distribution The observed range of variation within a system, encompassing both expected and exceptional cases.
Expected Distribution The normal range of variation that reflects standard operating conditions and acceptable fluctuation.
Excessive Distribution Outliers or deviations that exceed the expected range and may signal anomalies or risks.
Exception Management A targeted response mechanism for handling excessive distribution beyond acceptable thresholds.

By formalizing the boundaries of expected distribution, this model empowers organizations to manage complexity without overreacting to routine fluctuation. Exception management becomes a strategic tool for identifying meaningful deviations and responding with precision.
