Any book recommendations on lean and systems thinking in SaaS organizations?

• integrating dev/ops into customer support and other way round
• metrics for "customer happiness"
• team boundaries: rights and responsibilities: what to do if conflicting goals? How does the system find out that it might have conflicting goals.
• sustainable business focussing on flow rather than ob short time profit. What are the cultural and technical foundations of a sustainable SaaS business.

I already read "Web Operations", "Kanban", "Agile Management for Software Engineering: Applying the Theory of Constraints for Business Results" but there is too little focus on SaaS IMHO.

"Moreover, people with a limited action repertoire often impose old categories to classify what they see and mislabel unfamiliar new problems as familiar old ones so that they can act on them. For example, if firms traditionally decouple authority from responsibility and hold frontline people responsible for outcomes but don’t give them the authority to ensure those outcomes, this limited way of working may well be imposed mindlessly on new fast-moving situations where high performance is possible only when responsibility and authority coincide. There’s more than a grain of truth to the saying that when all you have is a hammer, every problem looks like a nail."
