Relay races are lost in the handoff more than on the track. Passing things on well is a skill.

Most failures happen in the gaps between people rather than inside anyone’s work. The individual parts can each be done well and the whole thing still collapses at the moment of transfer, because nobody thinks of the handover as their job. It belongs to both of you and therefore usually to neither.

When you pass something on, say explicitly what is done, what is not, and what the next person needs to know. When you receive something, repeat back your understanding before you start. Two minutes of overlap prevents most of the confusion that gets blamed on the work itself.
