Leaders build systems that build tools.

They sometimes build the tools themselves if communication /finding help would take more effort and time than diy.

Any other deployment indicates waste (e.g. ego / needing to show off your awesomeness, or needing to upskill yourself because you aren't the right skill-shape for the job) or a company starved for capital that is sacrificing the long term for the short in order to survive.
