In this video, we're going to look at how to put together questions specifically to get at the problem hypothesis. Now, I've mentioned it's okay to have a little redundancy here, and what we want to make sure of, as we talk about the problems on here, is that we have a specific view of a example of them doing whatever it is that's of interest to us. So, we might ask them here, can you tell me about your process for heading to a new job? What's the first thing that happens? Question formulation like this helps the idea that you want a sequential narrative of what they're going to do, what happens next. Now, you can see the question from here that there's this alternative thing. If you feel like you've been through a specific example with them, and you feel good about that example, what you can do is play that back to them in brief. Hey, I heard that this is the first thing that happens, then this, then this, then this, and that mega theme to fill in some details for you, which may help get at the details of that problem scenario. Then, we want to look at what's difficult, what's hard, so what's hard about getting to jobs? What's hard about completing jobs? What's hard about making sure the customer is happy? These are things that we might find are relevant in the experience of a VHVAC technician. And then, this is basically just more leading version of these previous questions, which you should feel free to skip, if you feel like you got nice highly quality answers. But, we might ask here, what are the top five hardest things about dispatch? And so forth, you can sort to fill this out for the rest of the items we covered before, and this is something you would want to do if, for example, our subject said to us. Well, we ask them, what's the hardest thing about getting new jobs? Well, I don't know, driving is always tough. Well, you know, basically it's okay, then we might go to our top five version of the question to try and get more of a specific list. And here, we have a very similar formulation, but more directional about where they see themselves going. So, what do you want to do better this year? Is something you'd want to proceed with, and then or do first, and then you could follow up, if you don't get what you think you want or what you think you could get. With something like, what are the top five things to do better this year? And here, this could be a lot of different things, this is kind of a throwaway question. Hey, why isn't this or that on your list, if you're curious why they missed it, and that is about as leading a question as you can ask, but that's okay at this point because we're at the end of the interview. So, we looked at how to finish up an interview guide to get at both the problem scenario as well as the persona stuff that preceded this. Next, you'll go out and talk to real subjects, get answers. It's kind of like skiing, it's going to feel a little bit awkward the first few times you do it, but as you do it more it'll get better and better. Don't expect the first one to go really well, and don't let that discourage you,. Try it a few times, iterate on your interview guide, iterate on the circumstances under which you interview them. You'll definitely want to iterate on the way that you take notes. I like to take notes on the laptop. I can type relatively fast, and I like to have those nice full transcripts that I mentioned are so important, so I would try that out. You can also try recording the interviews. Most subjects will react relatively okay to that, but I think what you'll find is that you have trouble finding time to actually go back and transcribe the whole thing. But, give that a try, and maybe it'll work for you, or maybe you have somebody that can do that transcription for you. If you have a team where someone else can comment, take those notes for you while you lead the interview, that's great and that works really well. Those are few tips, give these a try. There's some supplemental things in the lesson materials, and good luck talking to these real subjects.
