Judgment vs. Analysis: A Path to Effective Action

 This post introduces a conceptual model that contrasts intuitive judgment with structured analysis as pathways to effective action. By mapping how factors are interpreted—either through everyday reasoning or MECE-based decomposition—the framework reveals how the quality of insight influences the quality of measures. It invites reflection on how organizations and individuals move from reactive ideas to deliberate, impactful decisions.

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


Entity Name Description
Factor A condition or variable that influences the nature or outcome of a situation.
Common-sense Judgment Interpretation of factors based on everyday experience and intuitive reasoning.
MECE-based Analysis A structured method of decomposing factors into mutually exclusive and collectively exhaustive categories.
Ad-hoc Measure A spontaneous or reactive action derived from intuition or immediate need.
Effective Measure A well-designed action rooted in systematic analysis and aligned with intended outcomes.

By distinguishing between judgment and analysis, this model clarifies how the origin of insight shapes the effectiveness of action. It encourages a shift from reactive improvisation to structured decision-making, especially in contexts where precision and impact matter.
