About processes:
You add a process when you want repeatable results.
Adding blocking, synchronous steps involving people slows things down. Adding non-blocking, asynchronous, tool assisted steps are less intrusive in people's work.
About hierarchies:
You add hierarchies in your organization when your quorum involves too many people and things slow down. Hierarchies exist to make consensus building simpler at the cost of representing fewer people and all the associated consequences. Hierarchy must not be abused. People need to be respectful towards others regardless of hierarchy. Each contributor is important.
About quality and technical debt:
If you are always reacting to defects, you lost control of your product. You can no longer plan because you are too busy reacting to ad-hoc unplanned work. This is unprefessional and unnecessary. Keep things under control by being preventive, proactive and professional.
If someone tries to convince you that non-functional requirements cannot be sold, remember that person that person to focus on functional requirements and leave the non-functional requirements to the engineers.
