Gantt chart

delivery & projectsreviewed by the Forge team · 8 June 2026

A visual timeline that shows a project's tasks, their durations and how they overlap or depend on each other.

For example, an agency maps a campaign on a Gantt chart - research, then concepts, then production, with the client review built in - so everyone sees what happens when and where the squeeze points are.

Why it matters to agencies: a Gantt chart turns a project plan into something everyone can see and reason about, exposing dependencies and bottlenecks before they bite. It helps agencies plan capacity, set realistic milestones, and show clients a credible timeline rather than a vague promise.

common mistakes
  • A beautiful chart no one updates.
  • Over-detailing tasks no one tracks.
  • Ignoring dependencies, so slippage cascades unseen.
common questions
What is a Gantt chart?

A visual timeline that shows a project's tasks, their durations and how they overlap or depend on each other.

What does a Gantt chart show?

Tasks as horizontal bars along a timeline, with their durations, overlaps and dependencies - a visual map of who does what, when.

Why do agencies use Gantt charts?

To plan and communicate timelines, spot dependencies and bottlenecks, and align capacity with realistic milestones.

What is the difference between a Gantt chart and a milestone?

A Gantt chart is the whole timeline of tasks; a milestone is a single key checkpoint marked on it.
