【正确答案】{{U}}When{{/U}} falling behind the schedule, {{U}}the first thing we should do{{/U}} is to find out the root cause of falling behind.

At the same time, motivate and encourage them to improve their efficiency, and make concerted efforts to meet the schedule. {{U}}Finally{{/U}}, we have to give up the old plan and design a new one if we fall behind the schedule too much.
