Progressive Sharpening
Features start optional, become ergonomic for the curious, then essential to the power user — the progression runs uphill, never the reverse.
Mature software has a shape: new users see a small surface, intermediates see a few keyboard shortcuts, and power users see a command bar. The progression runs uphill, never downhill. A feature that’s essential on day one forces every new user to climb a wall they didn’t know existed.
This pattern is the antidote. The shape of the surface should sharpen with the user, not against them.
When to use it
- Tools with a stable core audience that grows in fluency.
- Anywhere a “simple mode” toggle has been proposed.
When to avoid it
- Consumer products where convenience now is the only metric that matters.
What breaks when you get it wrong
The most common failure mode is the well-meaning onboarding tour. “Here are the seven things you can do with this product.” The new user, presented with seven doors, picks none of them and leaves. A power user, told about seven things they already know, resents the patronising email. Progressive sharpening means: at any given moment, show the user the doors that match their fluency. Don’t show them the ones they haven’t earned yet — they’ll see those doors when they’re ready to walk through them.
