Harmonogram

Harmonogram is a timetable or schedule that lists tasks, their estimated durations, planned start and finish dates, and dependencies in order to coordinate activities within a project, program, or production process. It serves as a planning and control tool to align human resources, equipment, and materials with intended timelines.

The term is used in several languages, notably Polish, where harmonogram is the common word for a project or production schedule, and in German, where harmonogram (often as a loanword) appears in technical planning contexts. In English, the closest equivalents are schedule or timetable, while a harmonogram can also be presented in a tabular form or as a chart akin to a Gantt chart.

A typical harmonogram includes elements such as tasks or work packages, planned and actual start and end dates, durations, dependencies or precedence constraints, assigned resources, milestones, and constraints or baselines. It may be presented as a simple table, a narrative plan, or a graphical representation.

Creation and use involve defining activities, sequencing them, estimating durations, and assigning resources. The harmonogram is commonly updated to reflect actual progress, enabling monitoring, scheduling adjustments, and performance analysis. It supports decision making in fields like construction, manufacturing, software development, logistics, and public administration by highlighting critical paths, bottlenecks, and deadline risks. Related concepts include project schedules, network diagrams, and Gantt charts.
