All solid advice. I would add: If this mistake happens in the business context, commit to a root cause analysis, perform such with all involved parties and stakeholders, use a methodology such as Toyota’s Five Whys, identify areas for improvement, share your report, and resolve issues in a timely manner. The above will not only improve your processes so failures are less likely, it will also demonstrate a commitment to quality and improvement to all observers.
