Variety attenuation

Summary

Attenuation protects a regulator from being overwhelmed. It can simplify, buffer, aggregate or redesign demand. It can also erase inconvenient people and conditions if the boundary and purpose are wrong.

Implications for practice

Forms, triage, standards, thresholds and dashboards are attenuation devices. Their value depends on whether they preserve the differences needed for responsible action.

Key distinctions

• attenuation vs denial
• filtering vs distortion
• standardisation vs loss of requisite detail
• environmental redesign vs internal processing

Historical development

• Ashby's variety engineering
• communication channels
• management cybernetics
• service and process design

Ideas it depends on

• variety
• observer and purpose
• channel capacity
• regulatory task

Further developments

• triage
• standardisation
• aggregation
• buffering
• exception handling

Connections to practice

• state what variety is removed
• preserve routes for exceptions
• test who bears the discarded complexity
• redesign demand rather than merely hiding it

Common confusions

• less variety is always efficient
• standardisation is neutral
• what is not measured does not matter
• aggregation preserves all relevant meaning

Further checks

• Ashby primary passages
• Beer variety engineering
• forms and failure demand
• ethical attenuation
