> Progress is more like a hill than a straight line. Uphill: figuring things out (uncertainty, unknowns, problem-solving). Downhill: making things happen (certainty, confidence, execution)

This is the first time I've seen a "hill chart" and I found it a little confusing to look at - maybe because the shape looks like a normal distribution, where "the sides" are more uncertain and not less uncertain. If one turned a hill chart inside out, you'd get a chart like a dartboard, where as things are more certain you are closer to a bullseye in the middle, and less certain you are further away. I could see looking at OKRs that way.

I kinda like the hill chart but TBH it shouldn't look like normal distribution, but more like a half-circle. In my experience, most (SW) projects (at all levels of granularity) are S-curves (and not straight lines like in burndown chart). You're slow at beginning, because you're learning the domain and finding good abstractions. You're slow at the end because you're working out the kinks and fixing little details. The fastest progress is in the middle. So if the hill chart is supposed to show the difficulty in progress, it should look kinda like a derivative of inverted S-curve.

Going up is difficult but going down takes a lot longer than expected from the top, usually; so yeah, the hill should be skewed to the left and have a fat right tail.
