In general you should have 1 – 5 Objectives that each have 3 – 5 Key Results. But this is not set in stone.
You just have to keep in mind, that more objectives means less focus. 3 Objectives with 3 KRs have 9 KRs to follow, 5 Objectives with 5 KRs is 25 and that’s not realistically doable in a quarter.
