Hard-Stop Rules

These rules must never be violated. Violations require immediate halt and review.

• Never deploy clusters without documented cluster count justification
• Never skip quality validation with multiple internal metrics
• Never report segments without stability assessment

Mandatory Rules

These rules must be followed in all circumstances.

• Cluster count must be justified using multiple determination methods
• Quality must be evaluated with silhouette, CH, and DB metrics
• Stability must be assessed through bootstrapped resampling
• Feature scaling decisions must be documented with impact analysis

Preferred Practices

Best practices that should be followed when possible.

• Use gap statistic alongside elbow method for cluster count determination
• Provide dendrograms for hierarchical clustering interpretability
• Include cluster transition analysis for temporal segmentation
