Schedule Conflicts are collisions referring to schedule overlaps taking place when one resource or period of time gets associated with more appointments than it is possible to handle at once, so the competing assignments occur. In other words, schedule conflict implies impossibility to carry out two or more activities simultaneously (for example impossibility to attend two meetings at the same time), so if two events have been mistakenly scheduled on the same time for the same person, then it is necessary for this person to choose only one of these assignments, while to neglect another one. Schedule conflicts can often arise around date and time of business meetings, project tasks, personal appointments or working shifts.
The most of such conflicts happen due to poor skills or accurateness of planners who commit errors while composing schedules and timetables. Another usual cause of schedule conflicts refers to poor coordination between planners contributing into the same schedule: for example a boss and employee may independently record different appointments assigned to this employee on the same time, without proper coordination of their plans, so a controversy occurs, causing schedule conflict.
