Gantt Chart vs Timeline

Gantt Chart vs Timeline starts with a clear outcome, reliable dates and realistic dependencies. This guide presents a practical workflow you can apply immediately in Plan.podziel.pl.

Where to start

Write down the project outcome, final deadline and major phases. Break each phase into tasks with a clear start and finish. Measurable task outcomes make progress easier to assess.

Prepare the data

For every task, define a name, dates, owner, status and predecessors. Keep date formats consistent. When importing from Excel, review column headers and ambiguous date formats before accepting the data.

Dependencies and sequence

Finish-to-Start is the most common relationship: the successor begins after its predecessor finishes. Start-to-Start supports parallel work, while Finish-to-Finish synchronises completion. Start-to-Finish is uncommon and needs careful review.

Check realism

Review weekends, non-working days, resource availability, waiting times and buffers. Shorter bars do not make the real work shorter. Treat the schedule checker as a checklist rather than a deadline guarantee.

Export and update

After reviewing the plan, download JSON as an editable backup and PDF or SVG for presentation. Update progress regularly and create a new baseline whenever the approved project scope changes.

Common mistakes

• oversized tasks without intermediate outcomes,
• no time for acceptance and revisions,
• dependency cycles,
• one person assigned to overlapping work,
• no buffer before the final deadline.

Summary

A useful schedule is readable, maintainable and based on explicit assumptions. Because the tool works locally, download a JSON backup regularly.
