Think about relationships between nouns and verbs.
When you combine nouns with appropriate verbs, the resulting sentences can be referred to as requirements for what you’re making.
From the previous example:
- An author can write a post.
- An author can delete a post.
- Any user can share a post.
- Any user can read a post.
This list of requirements defines the ideal solution. Each requirement tells us who should be able to do what in the eventual state.
When you take the time to make requirements concrete and prioritize them, you can better understand what you’re actually making.
If you’re designing an interface that prioritizes reading, it will be fundamentally different than an interface that prioritizes writing, even with the exact same list of requirements.
