The four models
Flat task lists treat a project as an ordered queue of items. They are the fastest model to start with and the model most to-do and ticket tools are built on.
Gantt / timeline tools bind every task to dates on a calendar and draw dependencies between bars. This is the classic project-management model, at home in date-driven, fixed-scope work.
Whiteboard canvases are freeform: sticky notes, shapes and arrows anywhere. Superb for workshops and early thinking; the "plan" is a drawing, so nothing is structured or trackable by the tool.
Graph-based (DAG) planners — the category Planiq is in — model tasks as nodes and dependencies as edges. Structure is first-class: parallel tracks, convergence points and critical paths are visible properties of the plan, and execution data (deadlines, time, discussion) attaches to the nodes.
Side by side
| Dimension | Flat list | Gantt / timeline | Whiteboard | Graph / DAG (Planiq) |
|---|---|---|---|---|
| Core data model | Ordered rows | Tasks bound to dates | Freeform shapes | Nodes + dependency edges |
| Dependencies | Workarounds (links in titles, subtasks) | Supported, but every change cascades through dates | Drawn arrows — decorative, not computed | First-class; parallel work and blockers are structural |
| Re-planning cost | Low, but structure lives in people's heads | High — timeline shifts ripple everywhere | Low, but nothing else updates with it | Local — moving a branch doesn't touch unrelated work |
| Exploratory / branching work | Poor fit | Poor fit — branches don't have dates | Good for sketching, no follow-through | Natural fit (research trees) |
| Execution tracking | Strong (statuses, assignees) | Strong (dates, baselines) | None — usually paired with a second tool | On the graph: deadlines, time tracking, chat per node |
| Stakeholder communication | Progress percentages | Excellent for date commitments | Good for workshops | Read-only shared boards; AI summary of the graph |
| Best for | Independent tasks, queues, personal work | Fixed-scope, date-driven projects | Ideation and workshops | Dependency-heavy, parallel or exploratory projects |
Where Planiq is not the right fit
If your work is a queue of independent tickets, a list tool is simpler and better. If your deliverable is a date commitment against a fixed scope — a venue booking, a regulatory deadline with known steps — a Gantt chart communicates it more directly than a graph. And if you need freeform drawing (diagrams, wireframes, workshop boards), a whiteboard is the right surface; Planiq's canvas is structured on purpose. Planiq earns its place when dependencies, parallel tracks or branching research are the thing you are actually managing.
Choosing in practice
Look at your last three planning failures. If they were missed handoffs and "I didn't know that was blocking us", the structure was the problem — try a graph. If they were missed dates on known work, a timeline serves you. If plans never survived contact with the team, the model matters less than making the plan the shared, live surface everyone works on — which is the part real-time collaboration fixes regardless of model.
