Being able to make an educated analysis before taking action is a really important skill to have. Tell the hiring manager about the methods you take before implementing change.
"Before I implement change on the job, I will do a full risk vs reward analysis. I would then consult my superiors and look for similar case studies from other facilities. Then, I would put out a facility wide memo, outlining the pending changes just to prepare my staff. Finally, I will then bring in the necessary experts to train my staff on the changes, if required."
