Foundation review
Different evaluation axes
Security, Reliability, Performance Efficiency, Cost Optimization, Operational Excellence, and Sustainability address different primary questions, even when one change affects several pillars.
Use the requirement
Map the stated outcome—protection, recovery, efficient resources, lower spending, effective operations, or lower environmental impact—to the corresponding pillar.
