Nielsen's H7: accelerators — unseen by the novice — speed up interaction for the expert, so the system serves both. Shortcuts, bulk actions, saved templates and personalised defaults let frequent users fly, while the guided path remains for newcomers. Friction multiplied by frequency is where products quietly die.
Where it comes from
A professional kitchen runs on mise en place — every ingredient pre-cut, every tool in reach — because a dinner rush leaves no time for the novice path. The home cook follows the recipe step by step; the chef has compiled it into muscle memory and staged shortcuts. Same kitchen, two speeds. Nielsen's H7 asks software to be that kitchen: recipes on the counter, mise en place for those who cook here every night.

Support tools turn a 90-second answer into a 2-second insert for questions asked 50 times a day.
- UPI favourites
Payment apps pin your frequent payees — the 100th transfer takes two taps, not a search.
