Online Gantt Chart

Turn the schedule into a plan everyone understands.

Map tasks, dates, milestones, and dependencies on a shared canvas. Use a Gantt chart to review what happens next, who owns it, and which work is waiting on something else.

Product release timeline in Mockitt with project phases, task bars, shared comments, and a review note.
Bring tasks, timing, and team feedback together in one visual plan.

What a Gantt chart does

One timeline. Three practical questions.

A Gantt chart places work on a timeline. Horizontal bars show when tasks start and finish; connections explain their order. Use Mockitt Whiteboard to discuss the plan alongside your project notes and diagrams.

01

What needs to happen?

Break a broad goal into trackable tasks. Give each task an owner and a clear definition of done.

Outcome → work items → owner
02

When does it happen?

Show planned start and finish dates. Add milestones for decisions, handoffs, and release dates.

Dates → milestones → buffer
03

What depends on it?

Make the handoffs visible. When a task slips, review which later tasks are affected before moving the dates.

Predecessor → dependent task → risk

Build the first version

From an outcome to a workable plan in four steps.

Start with the next deliverable, then work backward through the decisions and tasks it requires. Keep the first plan small enough for the team to review together.

1. Define the outcomeWrite down what the team will deliver and how it will be accepted.
2. Break down the workAdd tasks, owners, and rough duration estimates.
3. Place the milestonesMark review, handoff, and launch points. Leave room for uncertainty.
4. Check the sequenceWalk through dependencies and resource conflicts before agreeing to dates.

Tasks, milestones, and dependencies

Make “who is waiting for whom” visible.

A timeline becomes useful when it explains the order of the work. Separate tasks that can run in parallel from tasks that need a completed input.

Task bars

Include a specific task name, an owner, planned dates, and an acceptance condition.

Milestones

Mark a decision or completed outcome, such as an approved design or a release candidate. A milestone is not another week-long task.

Dependencies

Record the input a task needs before it can start. Review the chain when a scope change or delay appears.

Review the same plan

Keep the discussion close to the work.

When a plan changes, the team needs more than a new date. Leave the reason, the affected task, and the next decision next to the timeline.

Review the impact first

Discuss the tasks and handoffs affected by a change before updating the schedule.

Write down the decision

Capture the owner, the agreed action, and the next check-in so the review produces an actionable result.

Keep the source of truth clear

Share the current plan and explain what changed. Update the chart from confirmed progress rather than assuming a calendar date means a task is complete.

Example review notes · fictional project

PM
Product · Design review

The approval flow needs one more error state. Does that affect the engineering handoff?

Task: review the checkout prototype
UX
Design · Next action

I’ll add the error and retry path before Thursday’s review. The handoff stays on Friday.

Owner: design lead · check-in: Thursday
QA
QA · Dependency

Add the retry behavior to the test scope so it is included in acceptance.

Dependent task: acceptance testing
A useful review captures the reason, the owner, and the next action. These are sample planning notes.

Release review packet

Ready for the next handoff?

  • Deliverable and acceptance criteria
  • Named owner for each task
  • Review and release milestones
  • Dependencies and known risks
  • Current status and next check-in
  • Links to requirements and design
Use the timeline as an overview; keep the supporting detail attached to the project.

Review and handoff

A plan should be easy to read and possible to act on.

Before sharing, walk through the critical handoffs. Make sure the next team has the information it needs, not just a start date.

Before the review

Highlight decisions, late tasks, and dependencies that need confirmation.

During the review

Record the decision beside the relevant task and assign a follow-up owner.

After the review

Update the schedule, share the current version, and agree on when the team will check progress again.

Connect the plan with your prototype

Three ways to use the timeline

Choose the project. Then replace the sample work.

These examples show different ways to organize a plan. Use them as references, then confirm the real scope, owners, dependencies, and dates.

Start with the next deliverable

Build a project brief you can discuss with the team.

Choose a project type and add a name. Copy the starting brief, then fill in real owners and dates. Nothing here connects to or changes your project data.

Choose a project

Start with the deliverable, then confirm the tasks, owners, and dates with your team.

Questions, answered

Before you start

When is a Gantt chart useful?

It is useful when work has a defined time frame, several tasks, and dependencies. Common examples include a product release, campaign launch, research study, or cross-team implementation.

How is it different from a task list?

A list shows what needs doing. A Gantt chart also shows when the work happens, which tasks overlap, and which tasks depend on earlier work. The task list can be the input to the timeline.

Do I need project-management experience to start?

Begin with one deliverable, list the work it requires, and assign owners. Add the likely order and duration, then review the assumptions with the people doing the work.

Does the chart automatically track live project progress?

Use the whiteboard for visual planning and team review. Keep progress current by updating the plan from the team’s confirmed status; automatic time tracking and repository synchronization are separate from drawing a timeline.

Make the next review count

Start with one task. Make the next step clear.

Map the timeline, discuss the dependencies, and agree on what happens next.
