Looking back at recent events lifted performance by about a quarter

The review

1. 01

   Who took part

   2,136 people in 46 samples from 31 studies, in teams or alone, in medical and other settings. About 48% were women, and anyone under 16 was left out.

2. 02

   What they did

   People looked back at a recent event, using input from someone else or from recorded data, and talked about what to change. Some studies compared them with people who had no review, and others checked the same people before and after. A session took about 18 minutes, and studies used about three on average.

3. 03

   What happened

   Overall, performance rose by about a quarter, or about a fifth without the three biggest results. Team reviews that measured team results gave the biggest gains. Many studies did not split people into groups by chance, so cause is uncertain, and video made no clear difference.
