I think what they mean by “everything is about risk” is that by measuring risk they can decide how to approach an issue, project, or aspect of a project. I think it also relates to the fact that everything has risk. There is risk or hazard involved with every step of a project. There is the risk of starting a new project and with the design aspects of the project. They have to measure the risk to the company as well as the risk to stakeholders, being doctors, patients, etc. Risk is used in the majority of decision making during a project by comparing it to the rewards that the project would bring. Throughout the duration or the project risk comes up in multiple ways, which is when they use the risk matrix to see how severe the risk is and decide which of the four ways they want to handle it.
