Some lessons learnt for successful technology infusion
• Have a common data gathering interface– MUST allows (remote) multi-mission data acquisition– APSI will be the P&S experimental platform
• Listen for needs & avoid forced technology push– Operations community requires new operation concept– Iterative design process with users involvement– Show results and improvements
• Plan for an extended validation campaign– Continuous support is required for fine-tuning– Critical phase for accepting the “new”
