By using historical average flight times, adjusted periodically, and a standard turn time (time allowed to offload, clean, and re-board passengers and baggage), they maintain a planned schedule. It does create seemingly random departure times, but it's the math of scheduled arrival times plus the planned turn time.
Why do planes sometimes leave early?
Planes sometimes leave early if the pilot makes the call, but generally, flights that depart ahead of schedule are just a few minutes early. This shouldn't cause a problem as passengers are expected to be at the gate 15-30 minutes before and should have boarded the plane at least 15 minutes ahead of the departure time.

In air travel, as delays are both common and potentially expensive, the scheduled flight time is usually increased to about 110% of the expected flight time, however some airlines are reportedly now padding by as much as 50%.
Do planes leave exactly on time?
The published departure and arrival times for flights are based on the times the aircraft is at the gate. The actual flight time is generally less than the published flight time because the airlines “add” extra time for anticipated and unanticipated times such as taxi times; enroute weather delays, headwinds; etc.
