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.

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.

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
KPI-Centered Design
Despite evidence that employing a human-centered design (HCD) approach to product design yields a strong competitive edge, many companies neglect HCD or don't even consider it in the first place. One reason for that is probably that many who think they're working user-centered are practicing something entirely different: KPI-Centered Design. This article inquires into different forms of design processes, into the differences between proper HCD and KPI-Centered Design, and how a resonable compromise can look like: Formulating hypotheses based on evidence rather than just KPIs or gut feeling, and complementing quantitative experimentation with more qualitative insights.
5 Foolproof Conversion Rate Optimizations for Your E-commerce Business
When hearing conversion rate optimization, many think of the application of psychological principles such as social proof or scarcity. But before employing those, e-commerce businesses first have to get their fundamentals down—which many don't. In this article, I present five foolproof (and proven) ways to optimize your conversion rate: optimizing your checkout, getting rid of shipping costs (as much as possible), focusing on usability, getting rid of dark patterns, and gaining a deep understanding of your customers.
