I work for a tech company that has major assets, A and B. My team develops and looks after A, my colleague Bob's team develops and looks after B. Both the teams work independent of each other.
My team plans for all contingencies, which ensures that we recover from any failures quickly with minimal disruption. Bob's team works hard too but from what I can see their contingency plans are not so good and failures are a bit more troublesome for them. They're very focused on the development end.
I have been noticing potential points of failure that would have B in some serious trouble. When I talk to Bob about contingencies for these, his response is "eh don't worry about it". Bob is also the super senior rockstar in the whole org. I am a level of hierarchy beneath him.
I believe it is only a matter of time until a catastrophic scenario occurs. When it happens, the company will logically pull my team to get B back up and running. We'll be stuck working nights and weekends. I believe this to be inevitable.
To prevent this, I have to get Bob to recognize what I see, and to take it seriously, and do the contingency planning and testing etc. We can't just hire more people.
So how do I communicate this to Bob?
