Tales of Design & User Experience (ToDUX) #4 ⁂ Dear readers and friends, I hope you’re all doing good. 😊 I have a two new pieces, both of which have been published in the UX Collective. The first one—“Listen to users, but only 85% of the time”—investigates why it’s not in the best interest of… Continue reading There is such a thing as too much data
Semantics *do* matter
Tales of Design & User Experience (ToDUX) #3 ⁂ Dear readers, Greetings from Barcelona! 👋🏻 I have a new piece on the differences between UX, Digital Product Design, and UX that has been published on my blog as well as on uxdesign.cc. UX vs. Product Design vs. UI Why did I write yet another article… Continue reading Semantics *do* matter
UX vs. Product Design vs. UI: The Never-Ending Battle
Digital product design teams are often referred to as “the UX team” or “the UX/UI team,” which are terminologies that can significantly disturb a proper understanding of what UX and digital product design actually are and what a digital product design team does. For one, the user’s experience can’t be designed in the first place, and “doing UX” goes way beyond the scope of digital product design. For another, saying “UX/UI” isn’t meaningful since they’re neither the same nor separable concepts within a process; one can’t “do UI” without also “doing UX.” Generally speaking, digital product design covers design research, interaction design, and visual design, and it’s a much more accurate term for what’s commonly referred to as “UX” or “UX/UI.” We believe a proper understanding of terminology is essential for being able to deliver one’s best possible work as a designer.
“We Need to Get Rid of Significance in A/B Testing, Seriously!” Published in ACM interactions
The way A/B testing is done in many—if not most—companies today, p-values and significance are pretty much meaningless. Still, decision models often only allow treatments to be implemented if they achieved a "significant uplift". One better alternative is to employ a Bayesian approach which allows to report probabilities for minimum uplifts and to calculate ROI on a case-by-case basis.

Tales of Design & User Experience (ToDUX) #2 ⁂ Dear Subscribers, this is the first newsletter sent from my new home, which is indeed Barcelona 🏖️, and I wanna use it to update you on a couple of things. We still need to get rid of significance in A/B testing First of all, my piece… Continue reading Vamos a Barcelona 🏖️
We Need to Get Rid of Significance in A/B Testing
Tales of Design & User Experience (ToDUX) #1 ⁂ Dear Subscribers, Welcome to the first issue of ToDUX (= Tales of Design & User Experience; I’ve skipped the “& Other Stuff” for the acronym). But first things first—thank you all so much for joining my mailing list. I feel very honored. 🙂 As promised, I… Continue reading We Need to Get Rid of Significance in A/B Testing
User Experience Is an Elusive Thing, or Conversion Rate & Average Order Value Are Not UX Metrics!
In this article, I review six metrics commonly used to measure UX: conversion rate (CR), average order value (AOV), task success rate, time on task, Net Promoter Score® (NPS), and the System Usability Scale (SUS). CR, AOV, and NPS do not fulfil the definition of a UX metric while task success rate, time on task, and SUS do. Still, none of the metrics (alone) is suitable to reliably measure the UX of a digital product.
Creating Medium-Fidelity Prototypes for AR/VR Experiences
Prototyping in 3D isn't the same as in just two dimensions. Compared to regular, flat websites, augmented and virtual reality have very different requirements when it comes to creating prototypes. To close a gap in the medium-fidelity range of AR/VR prototyping methods, we've created 360theater, which makes use of dioramas and 360° content for creating physical-digital prototypes. We've used our new method in workshops with design students and found that it comes close to the final experience while complementing other methods with different levels of fidelity.
My Ultimate List of Books You Need to Read If You Want to Truly Understand Digital Design: A Work in Progress
This list contains the books I believe everyone who wants to truly understand what digital design is all about needs to read. I've tried to roughly categorize them into more foundational topics and then somewhat along the double diamond: finding the right problem and finding the right solution. To provide a glimpse into the future, I also list some books on designing for an with (a selection of) novel types of interfaces.
“Growth Marketing Considered Harmful” Published in i-com
I'm proud that my article "Growth Marketing Considered Harmful" has been published in the latest issue of i-com ‒ Journal of Interactive Media. Abstract: In today’s e-commerce industry, conversion rate optimization is often considered essentially the same as user experience optimization. In addition, there is a strong focus on quantitative experimentation, which some deem a… Continue reading “Growth Marketing Considered Harmful” Published in i-com
