A hill chart is a visual tool for tracking tasks and projects, using the metaphor of going up and down hill to communicate the different phases of work.
> Every piece of work has two phases: an uphill phase where you figure out your approach, and a downhill phase focused on execution.[1]
I appreciate hill charts because they embrace the fuzziness of task-based work. Unlike rigid progress metrics like "done/not done," percentage completion, or T-shirt sizes, hill charts offer a more nuanced way to describe progress. If you export the chart each time you update it, you can also detect trends over time.
