Infrastructure Redundancy vs Investment Cost

Apply ISO 22317 business impact analysis to rank infrastructure criticality and direct redundancy investment only where service interruption causes greatest societal harm.

Business Context

Urban resilience depends upon redundant power supplies, communication networks, transportation routes, water systems, and emergency facilities that continue operating when primary infrastructure fails. While redundancy significantly improves service continuity, constructing and maintaining duplicate infrastructure requires considerable long-term investment. Municipalities must strengthen resilience without creating unsustainable infrastructure costs.

SmartCityTRIZ Resolution

Rather than duplicating every critical asset, municipalities should identify high-impact infrastructure through risk analysis and selectively introduce redundancy where service interruption would have the greatest societal consequences.

Applicable TRIZ Principles

Principle 3 – Local Quality prioritizes redundancy for the most critical infrastructure.

Principle 1 – Segmentation distributes resilience investments across priority assets.

Principle 15 – Dynamics adjusts redundancy strategies as urban risks evolve.

Expected Outcome

Stronger infrastructure resilience

Better investment efficiency

Improved service continuity

Lower lifecycle costs

Decision Indicators

Early indicators that resilience investments require adjustment include:

Critical infrastructure lacks backup capabilities.

Infrastructure failures affect multiple essential services.

Maintenance costs exceed resilience benefits.

Risk assessments identify single points of failure.

Recovery times continue increasing.

Monitoring these indicators strengthens infrastructure resilience planning.
