Systematic vs. systemic

The adjective systematic means (1) carried out using step-by-step procedures, or (2) of, characterized, or constituting a system. It typically describes carefully planned processes that unfold gradually. Systemic, which is narrower in definition, means systemwide or deeply engrained in the system. It usually describes habits or processes that are difficult to reverse because they are built into a system.

There is some gray area between the words. When there is doubt, it’s usually safer to go with systematic, which is older and more broadly defined.
