A short reliable window beats a long unreliable one
Sites frequently offer a two-hour window that in practice is interrupted by a late truck, an unfinished pick or a delayed load-out. A crew planning around it spends much of the time waiting or working around movements, and the result is inconsistent. A twenty-minute changeover that actually happens every day is a more solid foundation, provided the task list respects its length. A schedule built on the unreliable window quietly becomes a schedule nobody trusts.
The discipline is in sizing the work. Two or three tasks that can genuinely be completed, done properly and finished before movement resumes, are worth more than a longer list attempted at speed. The site sees a consistent result at a predictable time, and the crew is never in the position of being caught mid-task when forklifts start moving. It also makes the attendance easy for a supervisor to check.
