So you’re talking about SaaS / business tooling then? Again though, that’s just one of many segments of software, which was my point.
Also, even in that market it’s just not true to say that there’s no incentive for it to work well. If some new business tool gets deployed and the workforce has problems with it to the point of measurable inefficiency, of course that can lead to a different tool being chosen. It’s even pretty common practice for large companies to reach out to previous users of a given product through consultancy networks or whatever to assess viability before committing to anything.
