Principlev1
Preserve the ability to perform delegated work at acceptable
Preserve the ability to perform delegated work at acceptable levels yourself—if the delegate's disappearance would leave you unable to function, delegation has become dependency.
Why This Is a Principle
Derives from Automation degrades the very human skills needed to handle (automation degrades human skills needed when automation fails), Expertise Through Deliberate Practice (expertise develops through deliberate practice), and Expert performance in complex domains requires deliberate (expert performance requires practice targeting weaknesses). This prescribes maintaining skill through periodic practice, which is derived from axioms about skill atrophy and automation paradox.
