You are correct in saying that IBM service can effect ISV software products but I assume you have a process to test the environments before production rollout however. Fix on fail is one method of applying service, its not the one we use but it is a valid method however. The problem with "fix on fail" is that you always run the risk of hitting a problem that has already been fixed and could have been prevented if the service had been applied already. I generally apply the all available RSU's and available HIPERs not yet assigned an RSU identifier on a bi-monthly basis (6 times a year). Yes I sometimes get hit by being too aggressive but I can better defend my decision when that happens than having a system or subsystem outage due to not fixing a known problem.
