I am looking for idiom or a phrase I can use to describe rotational support process. The process explained as follows:
- Week 1: team member A and team member B are in charge of supporting group 1. Team member C and team member D are in charge of supporting group 2
- Week 2: team member D and team member A are in charge of supporting group 1. Team member B and team member C are in charge of supporting group 2
- Week 3: team member C and team member D are in charge of supporting group 1. Team member A and team member B are in charge of supporting group 2
- continue
This reminds me of rolling forcasts in finance and rolling-window in Computer. However, I am looking for an idiom/phrase which I can use for day-to-day work (not field specific). Is there any?
