In this episode of Beneficial Intelligence, I discuss knowledge decay. Knowledge decays over time, and skills you don't use become rusty. That's why it's a problem for out-of-work pilots that they're not flying.
Some knowledge decays and becomes less useful because the world moves on. An old-school telephone engineer's knowledge of electro-mechanical switches became irrelevant as phone exchanges became digital. Your knowledge of last month's hot JavaScript framework might be less relevant this month because there is now a newer and hotter toolkit.
But organizational knowledge decays much slower. That's why the knowledge in the heads of your experienced developers is still valuable, and you cannot just replace them with someone with the right tools on their CV.
It is your job as an IT leader to manage the knowledge of the people in your organization. For rapidly decaying technical knowledge, you need to offer constant learning opportunities so you don't lose the valuable long-term knowledge in the heads of your most experienced people.
