Does anybody know for long run successful aviation business without effective SMS ?
good question, what is the measure of success. Zero crashes ? Zero Deaths?
without a KPI you have no measure of success or failure in SMS terms.
As for the rest i can see your problem, and i really don't want to offend you but you need to look at your approach to change not the recipients.
Your posts tell a clear story that it is everyone else who is the problem, well its all of you as a team that have a problem, not you or them in isolation.
You say you keep telling them why they should change, and they don't like it it, have you considered that maybe they are right and you are wrong. ( a very alien concept on PPRUNE ).
Why not go back and ask them to come up with a better SMS for the company with a KPI in place. Effectively throw your toys out the pram and say ok if you can do it better go ahead and do it better.
BUT you must before anything else put some measure of success in place, you really needs some KPI's so you can take the emotion out of the equation and rely on numbers. Systems love Capta so go get some.
come back and tell me how many safety incidents you have had per 1000 operating hours for example, not just i want a better system.
Get the data, make it capta and base a decision on that capta and monitor going forwards. ( sounds a bit pathalogical doesn't it rather than generic ) which is where we came in i fear.
Why not try and convince us of your new system and see how that goes.
