We back one another up and prevent complacency from creeping into our ship. If you find a better way to do something, change it if you have the authority. If you don't, let your chain of command know about your better way. Supervisors should develop their subordinates through effective delegation. This requires that the supervisors delegate not only the task but also the authority and provide the resources to get the job done.
Safety is an absolutely vital consideration in every evolution - including routine ones.
Safety precautions are written in the blood of our sailors who failed to heed them. You must be intimately familiar with the safety precautions and features associated with the equipment you operate and to ensure they work properly. I am the only person onboard who can authorize the bypassing of any safety feature or standard operating procedure.
