Many times I&#x27;ve relied on new hires, and even specifically asked them to, for improving the documentation and&#x2F;or onboarding guides. Once someone has been in the team for a few months, they&#x27;ll picked up &quot;tribal knowledge&quot; and they&#x27;ll mentally fill in the blanks in any documentation (or obscure code). Those few initial weeks of someone with fresh eyes are precious for that.
