Yeah, even having learned to explain this shit in the IT Consultancy language of “supply contracts” and “mission critical”, it’s still not guaranteed that I’ll convince a manager to avoid or at least account for the higher exposure to outside risks when subcontracting certain things.
Nowadays, with 3 decades of experience in the Industry, I honestly think that the majority of managers, no matter how high in a company, are either incompetent as fuck or simply manage with as priority maximizing their next bonus in the full knowledge that they’re leaving traps for the next one to solve and if they do blow up during their own time, they’ll still personally end up better off by going for bonus-today-problem-tomorrow than refraining from doing so.
