The coreana fleet solution is very easy for us, as our team has little technical experience in this area of aviation software development (we are more focused on product management). It was not too difficult getting used with their system or learning how it works compared to other products we have worked before using. They did an excellent job from start-to-finish! This included working closely together after launch when there were issues being resolved quickly by them. We had some minor customization requested during implementation but they responded immediately once realized what needed done/changed versus just waiting until post go live which would've been worse case scenario if something went wrong then anyway. I think overall everything turned out great though so no complaints here. Our business needs changed over time requiring new modules added into existing systems such as flight ops & maintenance operations.
