This is what we call it when two teammates, usually engineers, join forces (pair) to solve a problem, and usually it’s pairing to code. One engineer “drives” another watches “over their shoulder” to give input. (This is often done remotely, such as over Zoom instead of side-by-side.)
Typically, the teammate who is learning something will “drive” while the more senior engineer gives guidance. At the cost of about a 15% increase in development time, pairing produces code with fewer errors, and even makes us happier at work.
