Thank you very much David. i have been using these mothods on accasion, depending on the context of the project and the amount and availability of users i can access. i have a question about the number of users or observations to do, especially if the research to distinguish diffrent user archetypes/ personas was not done. i understand we are not looking for statistical relevance and this is mainly qualitative. but if you have different markets/contexts/ user goals; how many users do you think is needed per method type(diary, JTBD, experince journey) ? again thank you alot
My rule of thumb is if the people I want to observe divide into clear types, I start with 5 of each type. If I don't know what different types there are, I start with 10 people. Types will emerge from the patterns in their different experiences. I usually aim for about 20 participants in total.
Hello David, I have a question regarding this topic. So as I ask people to, let's say, keep a diary of their experience, how much detail I should go into while explaining them my project? do I explain the whole project to them and the idea behind it or just give them as little detail as possible so they won't become conscious of their actions. I am a bit confused about that. thanks
If you're running a diary study, you're interested in the meaningful activity that people carry out. For example, if your project idea is a mobile to-do list, then the meaningful activity is around how people create to-dos and reminders -- everything from sticky notes on the fridge to tying a knot in a handkerchief. So you ask people to keep a diary describing how they go about the meaningful activity. You can make this as structured as you like -- there are a lot fo good resources online. Try these two: www.uxmatters.com/mt/archives/2012/07/a-closer-look-at-diary-studies-with-children-and-teenagers.php and www.annualreviews.org/doi/abs/10.1146/annurev.psych.54.101601.145030
@@DavidTravisthank you so much. That was great information. So with regards to the project I have chosen "tomorrow's shopping cart", Can I disclose this to the users that I will be asking for a diary study?
I just started my journey into UX at the UX Design Institute in Ireland and your videos are the perfect addition. Could watch them all day!
Awesome, thank you!
Very useful + explained very clearly + more resources in the description box.
David, you are a great teacher.
Glad it was helpful!
Thanks for the video David! Do field research for product idea validation make sense?
No. You do field research to validate the problem, not the solution.

What are the differences between cognitive and episodic interviewing?
