title: Time to open is highly correlated to code cycle time.

Time to open is highly correlated to code cycle time.

According to a study of 180,000 merge requests from 500 teams, time to open (first commit to merge request open) has an 87% correlation with code cycle time. This suggests that code ships faster when the decisions are smaller and brought to the team for input sooner. Indirectly, this may suggest that strong pairing practices make code ship faster.rD13
