The last dilemma relates to bad communication.

As Melvin Conway wrote in How Do Committees Invent? (proposing what is now called Conway's law (http://www.melconway.com/research/committees.html)):

In other words, the product you are building reflects the communication of your organization. A lot of the time, problems don't come from the technology but from the people and organization surrounding the technology. If there is any dysfunction among your developers and operations in the organization, this will show.

In a DevOps culture, developers and operations have a different mindset. They help to break down the silos that surround those teams by sharing responsibilities and adopting similar methodologies to improve productivity. They automate everything and use metrics to measure their success.
