Gantt Charts

The Gantt remains a great tool — when it's done right.

Why the Gantt Chart Still Matters

The Gantt chart, developed over a century ago, remains one of the most powerful visualizations for project schedules. At a glance, it shows:

  • Time layout: When work starts, how long it takes, when it ends
  • Parallelism: What work happens concurrently
  • Progress: How much of each task is complete
  • Milestones: Key dates and deliverables

The Problem with Dependency Lines

Lost in Vertical Scroll

Traditional Gantt tools draw lines between tasks to show dependencies. This looks elegant in demos with 10-15 tasks. In real projects with 100+ tasks, those lines become an unreadable web — and worse, they disappear off-screen as you scroll.

When a task bar is on screen but its predecessor is 50 rows up, the dependency line provides no useful information. You can't see where it leads. You lose context instantly.

How Consequent Does It Better

Instead of relying on fragile dependency lines, Consequent is evolving richly annotated Gantt charts with modern interaction patterns:

Clickable Constraint Navigation

Click on a constraint or predecessor indicator to jump directly to the driving task. No searching, no scrolling through tangled lines.

Localized Cross-Referential Data

Each task bar shows relevant constraint information inline — predecessor codes, SNET/FNLT flags, completion percentage. The data you need is where you're looking.

"Explain This Date" Tooltips

Hover over a calculated date to see what's driving it — which predecessor, which constraint, what calculation. No more mystery dates.

Why this works this way

Gantt charts are only useful if they explain the schedule. Dense dependency lines hide information at scale.

Consequent focuses on explainable, interactive details so planners can navigate cause and effect without losing context.

Using the Gantt Effectively

For high-level views

Collapse task groups to see the overall project shape. Summary bars show the aggregate duration of their children.

For detailed analysis

Expand specific phases and use the inline predecessor information to trace dependencies. Click through to understand the critical path.

For communication

The Gantt remains excellent for stakeholder communication. A visual timeline conveys complexity that spreadsheets can't. Export views for presentations.

The Bottom Line

Don't abandon the Gantt — it's been a great tool for over a century. But demand better from your tools. Graphical dependency lines were a fine idea in the 1980s. Modern project management deserves interactive, annotated, clickable interfaces that work at scale.
