Ambiguity arises largely due to designers thinking, “I own the design, why is product telling me what to tweak?”, engineers thinking, “I own the technical aspects of the product, why is product asking me to stop working on feature X?”, and product sometimes stepping on either function’s toes. In reality, product management should be viewed as the function in the middle that needs to make holistic trade-offs on all aspects of the product and represents the voice of the user (while making the proper business trade-offs).
