National and Regional SMS Data Management Challenges
We saw the enterprise-level data management nightmares that are plaguing most airports around the world as they comply with ICAO's mandate. (see ICAO Compliance Problem link) There are many competent, highly skilled safety managers working in these positions; however, they are not SMS data management professionals. This causes systemic troubles in the entire "national airport SMS organism."
Regional Challenges Continue From Enterprise Level...
Any attempt to get accurate, current reports from airports' SMS systems at the national level leads to suspicious and immediately outdated results. Coordinating data retrieval and data aggregation processes costs exorbitant amounts of money EACH time national or regional reports are required.
How can one perform a valid trend analysis on suspect and outdated data? Reports at the national and regional level are incredibly expensive to collate and impossible to create with any degree of accuracy. Months or even years may be required to compile reports identifying trends. By this time, new trends may be developing.
