Capability — content management, personalization, commerce, multi-channel delivery, search, analytics, workflow. Cost Efficiency — TCO (licensing + hosting + implementation + ops) inverted against normalized features. Higher = better value. Build Complexity — bubble size encodes time-to-production, talent availability, learning curve. Maintenance — ring color shows upgrade burden, security patching, vendor-forced migrations, operational overhead. Migration Tax penalizes cost efficiency based on vendor lock-in and exit difficulty. All scores reflect a 104-item framework evaluation.
