Risk response, where it is implemented
As per PMBOK section 4.3 Direct and Manage Project Execution also lists - the manage risks and implement risk responses activities. (page 83 PMBOK guide)
But the same activity (risk response implementation) is part of the Monitor and Control Risks process.
So, where exactly is the implementation takes place?
If there is a question which describes the situation on risk implementation and asks with process / process group does this belong; what can be the answer since PMBOK lists the same activity in both these processes.
Thanks in advance.
