Accountable
Everything should have an identified purpose and fulfill that purpose in a way that inspires trust.
- Does it fulfill its purpose?
- Can everything be justified?
- Are sources identifiable?
Clear
Empower the user to act with confidence by providing them with accurate, orderly data. Focus on one thing at a time.
- Is it free of unrelated or unnecessary elements?
- Does it perform as expected?
- Is everything consistent?
Efficient
Eliminate redundancy and apply the same solution to the same problem. Make flexible solutions that can be applied to related problems.
- Is it effortless?
- Is the next step obvious?
- Could this be done in fewer steps or said in fewer words?
Democratic
Educate and empower the community by addressing a wide audience. Make terms, concepts, and interface elements accessible for everyone.
- Is it understandable and accessible for a wide audience?
- Does the system support/articulate multiple “mental models” for how a user can interact with the data?
- Is navigating between these mental models easy?
