> So show me a methodology that mere mortals can implement successfully. There's an impedance between "Bob can do task of type A really quickly" and "we need to make sure that people other than Bob can do the task or else we have bus factor = 1 and this poses systemic risk". Clearly these goals are not really in conflict. In general, assign the work to Bob, but understand the effect on timeline in case Bob is unavailable. How long would it take if Bob isn't available? Is it worth the inefficiency from cross-training Mike? Is Mike even interested? Modern militaries are not majority staffed by combat soldiers. Less than 10%. The rest are support of one kind or another. Smart engineering leadership in large companies, if they care about shipping on-time, eventually realize that roles like PMs are less effective if they understand themselves to be bosses and more effective if they understand themselves to be support staff.
