 methods. I'm jumping right in, so we're talking about user research and what that means, typically upfront, but also done throughout the process. So there are different types of research. Again, depends on what your goals are and where you are in your process, design and development process. Three buckets typically called exploratory research, generative research, and evaluative research. And there's different methods that go in there. But the words themselves kind of explain an exploratory research and methods. You're really exploring the problem space used for probing, understanding, you know, what's happening in the current situation. Generative research, and you'll see participatory design and co design in that bucket. This is a little more hands on you can bring the users in to do different activities to understand how they might solve a problem that's kind of a really interesting way to see how they would think to solve problems and where many people are, you know, considering solutions and then evaluative research is done, typically when you have some solutions in mind, maybe some concepts or you've even built the thing you have designs or you have a system in place and you want to evaluate how that is working if where there are issues where there are places for improvement. So kind of three buckets of user research. And digging in even deeper, depending on the questions you're trying to answer there's a range of methods that you can pick from and combinations of these methods to help you answer your questions so on the right here maybe looking at the two different axes on the bottom quantitative versus quantitative research. So qualitative research is more direct your, you have the opportunity to probe and really dig deep with your participant. quantitative research, obviously, more indirect there's tons of survey methods that you see there. And that usually requires larger numbers and you can help you quantify the different responses that you're getting. So those can often be used in conjunction on the other axis is behavioral to attitudinal so again depending on are you trying to understand what users do. So that's some of those methods up at the top by tracking usability testing is a common one where you're watching people actually interact with a design or product, or attitudinal and again this is, you're asking more specific questions and seeing how people respond to things what their thought process mental models are interviews focus groups, participatory design is in there as well. One thing I want to drive home here is that this is just kind of a menu of research items there's no right or wrong way to answer your question it really depends on what constraints you might have maybe you're on a time crunch maybe you have limited access to potential research participants. So many different factors that go into actually choosing a method. This is just here as a guideline to help you understand, depending on what you're trying to understand, you know, seek to questions you're trying to understand what methods are available to you.
