7. Things to consider for LTSD  National vs International  Needs for harmonization and interoperability  Users and their requirements – need to learn their decision-making trees  Study existing services  WMO position and instrumentarium  Business case and who’s paying  Science and technology  Possible methodology – define “use cases”
