To rejig something is to move the pieces around and set them up in a new way. You might rejig a timetable, a team, a shop window, or a plan that is not working. It is informal, and you will hear it much more in British English than in American English. It often has a practical, slightly rough feel — not a grand redesign, more “let’s shuffle this until it works.” Americans are more likely to say rearrange, shake up, or (even more informal) rejigger. There is also a noun: a rejig of the cabinet means the jobs in government have been handed out again. Though actually, the jig part is an old verb for moving with little jerks, so the picture behind the word is giving something a shake, not drawing a new blueprint.
