I guess I'm just going strongly disagree on healthcare IT. Some struggle, but many embrace it. Early EHRs were bears, but anything remotely modern (i.e. kept up to date within the past decade) is very good. Implementations vary, obviously, and when organizations half *** it by choosing to use multiple systems, well that's dumb and frustrating. There is only one truly enterprise-level EHR - Epic - but it's expensive. Choosing less expensive alternatives for the hospital itself requires yet other EHRs for ambulatory settings. Do they connect properly? Does data seamlessly flow between them? Maybe... but even then, the EHR itself is fine, it's the interconnectivity that's lacking.
Regarding SAP... yeesh. Look, it's a decent enough application. The problem, in my experience, (one implementation in last career, and my ol lady is going through one now at her company) comes from half-baked planning and the fact that they're often trying to combine many, many, many sources of data that are an absolute mess. SAP requires discrete data fields for almost everything and if your legacy database combined things... well. Good luck!
