Plural of changeover; switches from one system, method, or person to another.
From 'change' (Old French 'changier') plus 'over' (Old English 'ofer'). The compound 'changeover' emerged in the early 20th century to describe transitions in manufacturing and broadcasting.
The word 'changeover' became crucial during World War II when factories had to rapidly switch from civilian to military production—entire industries would coordinate massive changeovers in days. Today it's everywhere from sports broadcasts to software updates.
