Start with the everyday
The most useful software often starts with an ordinary frustration: a document waiting for a signature, a merchant switching between tools, or a landlord trying to find the right information. Before a feature list comes a question: what would make this moment easier?
The best feature is the one that helps someone finish what they came to do.
Make the next step clear
A good interface helps people understand where they are and what they can do next. Clear language, thoughtful defaults, and predictable behavior can matter more than a long list of options. Each screen should earn its place by helping someone move forward.
Build around the whole journey
A task rarely begins and ends inside one screen. Think about what happens before someone arrives, the information they need along the way, and what happens after they finish. Better software respects the whole journey.
