I think it makes sense because SAP is focussed on operations management (inherently inside your business) and Qualtrics is focussed on whats happening outside your business. If you marry the two in an integrated way you cover the entire chain from "raw supplies in from this supplier through to customer not happy about quality of material from that supplier". So while on it's own Qualtrics might not be worth 8bn to anyone else it might well be worth 8bn to SAP.
