“You’re going to screw up. Accept it.”
Kerry Patterson, Joseph Grenny, David Maxfield, Ron McMillan, Al Switzler, from their book, “Influencer: The New Science of Leading Change.”
Production databases can be a scary environment for operators who are taking over the reins of a new OSS that has been implemented by others (eg vendors, integrators, etc). There tends to be a fear of the unknown of how easy mistakes will be to fix, or even whether mistakes can be overcome at all.
You’re going to screw up (or other members of your team will). Accept it! Plan for it.
It’s interesting that most OSS handovers include operational training (albeit usually too short), but rarely includes contingency training.
Contingency training should be set up by the vendor / integrator in a sand-pit environment and based on the major screw ups they’ve seen occur at previous customer sites as well as other major catastrophic situations they can envisage. Your team can also contribute to the syllabus through the knowledge of your local ecosystems and problems you can envisage.
