Are you wondering what a Gantt chart is and if it is the right tool for your project?
In a nutshell, a Gantt chart is a visual project planning tool that displays tasks as horizontal bars laid out across a timeline. Each bar represents a specific task, showing its start date, end date, duration, and relationship to other tasks.
Gantt charts typically include the following components:
- Task list: A list of all the individual tasks and subtasks required to complete the project.
- Timeline: A horizontal axis representing time, showing days, weeks, or months.
- Task bars: Each task is represented by a bar, with the bar’s position and length indicating its start date, duration, and end date.
- Dependencies: Lines or arrows connecting task bars to show the relationship between tasks, such as which task must be completed before another can begin.
- Milestones: Key project checkpoints or deadlines, often marked with a diamond shape.
- Resource assignment: Assigning a specific person or team to each task to clarify responsibilities and manage workloads.
- Progress tracking: The task bars can be shaded to show the percentage of completion, providing a quick visual of how the project is progressing against the timeline.
Because the entire work plan appears on a single horizontal timeline, Gantt charts make it easier to see how work fits together and how schedule changes ripple through the project.

What is a Gantt chart used for?
Gantt chart in GoodDay
A Gantt chart helps teams plan, organize, and monitor project work by showing tasks, timelines, and responsibilities on a single visual timeline.
Project planning
Teams use a Gantt chart to break a project into clear tasks, assign timeframes, and organize work from start to finish. This makes it easier to understand the full scope, estimate timelines, and set a realistic plan before execution begins.
Timeline visualization
Gantt charts provide a simple visual timeline that shows task order, key milestones, and overall duration. This helps teams and stakeholders understand the project flow without needing detailed explanations.
Tracking progress
By updating task statuses directly in the chart, managers can see whether work is on schedule or falling behind. This visibility helps teams correct issues early and stay aligned with the project timeline.
Workload balancing
Many teams use Gantt charts to check whether workloads are evenly distributed across team members. Seeing workloads in context helps managers adjust assignments before delays occur.
Cross-team coordination
When multiple teams contribute to one project, a Gantt chart shows how their work aligns across the timeline. This reduces communication gaps and helps teams coordinate shared deadlines.
Resource allocation
A Gantt chart shows when specific people or resources are needed, helping managers avoid overloads or conflicts. With a clear view of who is working on what, teams can distribute work more evenly and prevent bottlenecks.
Dependency management
Gantt charts show how tasks relate to each other, including which tasks must finish before others begin. This helps managers identify the critical path, plan parallel work, and maintain a smooth sequence of activities.
Stakeholder reporting
Gantt charts are often used in status meetings because they give a clear snapshot of completed work, current progress, and upcoming tasks. Stakeholders can quickly understand risks, delays, or changes in the schedule.

Gantt chart in GoodDay
With a Gantt chart, a project moves from initial planning to final completion on a single organized timeline. Tasks appear as horizontal bars, allowing you to see their duration, order, and overlap at a glance. Early planning activities are placed at the beginning of the timeline, while later execution and wrap-up tasks appear toward the end, creating a clear flow of work.
GoodDay automatically positions tasks based on their start and end dates, and dependencies can be added with one click to show how tasks relate to each other. Milestones stand out as key checkpoints that help teams understand major transitions or deadlines.
As work progresses, GoodDay updates task bars in real time, making it easy to track whether the project is moving as planned.
Although every project has different steps, the core structure is the same: a clear sequence of tasks, time-based visualization, visible dependencies, and easy progress tracking. This layout helps teams understand the project lifecycle from start to finish with minimal effort.
