Jason Yip:

When you work in team-based product development, you will need to deal with drift.

By drift, I mean an increasing mismatch in understanding about:

• the problem we’re trying to solve;
• the solution we’re attempting;
• each other and how to relate.
• Drift in shared understanding creates confusion, mistakes, and generally a bad working experience.

Daily standups ensure understanding is integrated across a team at least once a day.
