20x as many fixes to correct 80% of architecturally complex defects touch an Architectural Hotspot—a badly designed component causing problems System Level Measurement Is Critical 6 48% 52% 92 % 8% Architecturally Complex Defects Component- level violations % of total app defects % of total repair effort Architecturally Complex Defect A structural flaw involving interactions among multiple components that reside in different application layers Architectural hotspots provide a roadmap for remediating the worst risk, rework, and cost drivers
