Schedule

A schedule is a plan that arranges activities within a defined time frame, indicating when tasks start, how long they take, and when they are expected to finish. Schedules help organize work, coordinate events, allocate resources, and reduce conflicts by providing a reference for timing and sequencing.

Schedules appear in many forms, including daily timetables, weekly rosters, project timelines, production calendars, and transportation itineraries. A master schedule may summarize all activities, while individual schedules tailor to specific roles or functions. Timetables often show sequential tasks and dependencies to clarify how one activity leads to another.

Key components of a schedule include tasks or events, start and finish times, durations, deadlines, dependencies, and assigned resources. Schedules may also incorporate milestones, buffers, and constraints. They are dynamic documents that are revised as conditions change, such as delays, new information, or shifting priorities.

Common methods and tools for creating schedules include calendars, Gantt charts, the critical path method (CPM), and program evaluation and review technique (PERT). In practice, many organizations use software that automates calculations, visualizes timelines, identifies conflicts, and supports resource leveling and schedule updates.

Scheduling is used by individuals for personal productivity as well as by organizations to plan projects, manufacturing, logistics, and services. Its effectiveness depends on accurate estimates, realistic constraints, proactive monitoring, and the ability to adapt to changes while maintaining overall goals.
