Question

A large software company has multiple teams that keep independently building similar authentication libraries because they cannot easily see or contribute to each other's work. Leadership wants teams to share code internally, discover existing solutions, and accept contributions across team boundaries—while keeping the code private to the company. Which approach best addresses this goal?

Accepted Answer

Adopt InnerSource practices by making internal repositories discoverable within the organization and allowing cross-team contributions using open-source-style workflows

Answer

Publish all authentication libraries as public open-source repositories so every team can find and contribute to them

Answer

Require each team to purchase paid apps from the GitHub Marketplace to standardize authentication

Answer

Instruct teams to email zipped copies of their libraries to each other when duplication is discovered
