Gantt Chart

A Gantt chart schedules a project the way a to-do list never can — tasks down the left, time across the top, and each task drawn as a bar spanning the periods it runs. Name the project, then list up to ten tasks as "name | start-end"; give a task a span like 2-4 and its bar fills those periods on a shared ten-column axis. Seeing the bars laid over one another is the whole point: it shows what happens at once, where the crunch weeks stack up, and what's waiting on work that hasn't finished yet. A column is whatever unit you name — a week, a sprint, a day — so the same sheet plans a launch, a build, or a term. Sequence the bars so nothing depends on something that ends after it starts, and a period buried under too many bars is your warning to spread the load. Fill it in to pressure-test a plan, or print it blank and draw the bars by hand on the grid.

A Gantt chart lays your tasks down the left and time across the top, then draws each task as a bar spanning the periods it runs. What a to-do list can't show, the bars can: what happens at once, where the crunch weeks are, and what's waiting on work that hasn't finished. Give a task a span like Design | 2-4 and its bar fills weeks 2 to 4.

How to work it

One task per line, as name | start-end — the numbers are periods on the axis (1–10). A single number like | 5 makes a one-period bar; skip the span and the row still prints, ready to draw by hand.

A column is whatever unit you name — a week, a sprint, a day. Sequence the bars so the plan holds together, then watch for any period stacked with too much at once.
