# Total Airport Management TAM is the next evolutionary step beyond [[Airport Collaborative Decision Making]]. Where A-CDM focuses on the turnaround process and departure sequencing (primarily airside), TAM extends coordination across all three airport domains: airside (runways, taxiways, stands), terminal (check-in, security, gates, baggage), and landside (ground transport, parking, curbside). The core shift: A-CDM optimizes aircraft flow. TAM optimizes the entire passenger journey plus aircraft flow plus resource allocation plus commercial performance. This means connecting data and decisions that historically lived in completely separate systems run by different departments. SITA's Total Optimizer represents one commercial implementation. It lets airport operations teams dynamically weight competing objectives: operational performance, capacity provision, revenue generation, cost efficiency, passenger experience, and sustainability. The key word is "dynamically." Static weighting is easy. Adjusting weights in real time based on changing conditions is the hard part. ICAO's Global Air Navigation Plan frames TAM through the Aviation System Block Upgrades (ASBU): B0-ACDM establishes data sharing; B1-ACDM integrates airport operations fully into ATM. TAM sits at the B1 level and beyond. The practical challenge: TAM requires organizational integration that most airports lack. The airside team, terminal team, and commercial team typically report to different directors with different KPIs. Getting them to optimize jointly requires governance changes that are harder than technology changes. Same pattern as [[Bespoke Engineering in Industrial AI]]: the technology is 30% of the problem, the organizational change management is 70%.
