ECM, defined as a tool, has moved away from being a platform and morphed into a thin layer that supports business outcome rather than the ambition to manage content. This requires a totally different approach and skillset.

By now, we all know that there is no single enterprise-wide platform that supports the business goals related to content and it would be wrong to hold on to that command and control vision, similar like we had in the early days.

That’s the theory and the review of the changes in the last years. The best way to understand it is by trying to build an example. 
For our own organisation, we have the same questions related to content, collaboration and business processes. 
RedTree's founder, Pieter Ardinois is writing a series about 'the Future of ECM' , where he explains and explores the evolution of ECM and definition of content services and the role as an Service Integrator,

"Digital Transformation, the most overused term to date, might be just that. Not revolutionising but transforming formerly dominant applications into supportive and invisible layers, offering services that people take for granted. The obviousness of those services is not because people were trained or forced to use them, it’s because they know these concepts from their non-professional lives. The pitfall for enterprises is to define digital transformation as a practice or project and underestimating the technical complexity of those layers. This can be applied to numerous business domains. For ECM, in that sense Mr. Koehler-Kruener put it right. It has to be technologically focused."
