In a relay, races are often lost at the handoff. A lot of teamwork breaks at the handoff too.

The weak point in group work is rarely the individual parts. Everyone does their piece reasonably well and the thing falls apart in the gaps: who was sending it on, when, in what form, whether the next person knew it was coming. Nobody practises the gaps, because they do not feel like anybody’s job.

On the next group project or shift change, name the handoffs out loud before you start. Say who passes what to whom and when. Then practise the awkward moment itself, which is the only part that actually gets dropped.
