“Companies will no longer buy software. They will buy results.”

Software-as-a-Service becomes Service-as-Software.
In many companies, people have become the interface between programs: they copy data from one system to the next and hold together processes the software should carry. Every new problem gets a new tool, and every tool becomes another island.
The book describes what is changing now: software no longer just gets operated, it delivers the work itself, while people check, decide and take responsibility for the result. Marcel Karas shows what this means for a company’s process chain, roles and business model, and how to get there step by step.
