Classical project risk management

I've spent some time recently going over the PMBOK Sixth Guide, Sixth Edition PMP training materials created and published by Velociteach. At the same time, I'm using Mike Bissonette's book Project Risk Management: A Practical Implementation Approach to gain a deeper understanding of risk management. How can the PMBOK processes, including the tools, be leveraged to improve on project risk management?
The current PMBOK Guide, Sixth Edition, has this Risk Management process structure:
Planning

• Plan Risk Management
  Bissonette: "It is considered good practice...to conduct project risk management processes intentionally for projects that are inherently risky." Earlier the this book/guide, the author describes the increasing risks when projects are planned and executed in increasingly competitive industries and spaces. 
• Identify Risks
  Bissonette:  "Identifying project risks is considered by many to be the most difficult aspect of the project risk management process." The author then devotes three chapters of his book to this process. 
• Perform Qualitative Risk Analysis
  Here, the author makes the distinction between "individually identified risks" (relevant to this process) and "overall project costs and schedule risks" (relevant to the quantitative risk analysis process). 
• Perform Quantitative Risk Analysis
  Again, Bissonette, on why this separate process exists: "In most circumstances, the overall project cost and schedule risk assessment cannot be effectively determined by aggregating the individual risks." 
• Plan Risk Responses
  Here, responses are developed for the identified and analyzed risks. Bisonette notes: "Each response typically requires resources (time, people, and budget) to implement. If too few resources are available to cover all response strategies, priorities and trade-off decisions are necessary...."
  
  

Executing

• ​Implement Risk Responses*
  Velociteach's Andy Crowe provides an introduction to this new Sixth Edition process, which is in the Executing process group. This process implements the plans outlined in the five planning processes for this knowledge area.  It's performed after the planning processes, including Plan Risk Responses, are completed. 

Monitoring and Controlling

• Monitor Risks
  Bissonette puts this process in the context of the other PMBOK Monitoring and Controlling processes across the knowledge areas (that is, the similarities between Monitor Risks and other Monitoring and Controlling processes). He then describes drivers between planned and actual risks, including the emergence of unknown unknowns.
