用户模型及用例

Translated from Rich fulcher by google UX designer

"Hi, I'm Rich. Master's studies in computer science and computer program vision, but then I chose to be a designer, and now I am the design leader of the Google Android team. "

“I think it's tempting to start doing what you want most early on in the project.

If you are a designer, you want to start drawing;

If you're a developer, you want to build interfaces or start typing code.

Or go live as soon as you can.

But

What annoys you is that you do it with enthusiasm and confidence, but you have a hard time choosing the right direction for your product, and the only way to do that is to get to know your users. ”

“So, you need to start thinking, 'Who's the audience for my project, that's definitely not you, that's a bigger group.But how do I get to know them?How do I determine which features excite them, the use cases I want to sort through to give them goals, what those users need ”

“So the only way you need to think about the user is through the user to build your user model, such as their various goals and their usage scenarios.”

“When you have a user model, your next step is really to think about how they are using your product, and the only way to get that is by asking the user to complete a task that fits your use case, and theyEach step in completing a task can be broken down into a special sub-goal. "

“So you have user models and use cases, how does that affect your project?Well, generally I will do my best to give names to these models.Then I'll talk about special use cases, and if I talk about my own point of view, I'll do what I can to differentiate between repetitive words, assuming I'm a user. ”
