I was a king with an unlimited budget
Back in the late 80s I was a regional VP of Sales for a global transportation company. One of our competitors centralized their customer service and only a few days in, their national toll free number went to a dead end.
I mobilized our sales team and we picked off nearly $100M annual revenue that never went back to them.
Years go by, I move back to the USA and take a role with them heading up IT for their customer service and sales. (Long story moving from biz to IT) Six weeks in I meet with the exec committee over IT expenditures. I have a long wish list for redundancy that is breathtaking in $$$.
To their credit, nobody asked if I was sane. I was somewhat infamous in the industry for nothing related to sales or IT, so I had their respect. When questioned about the need for all of this NOW! I pulled out my old sales reports and passed them around. I informed them this was all of the new business that I had stolen from them from their call center outage those years ago. 100% approved, and I never once had to justify any of my budget requests after that.
