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.

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.

How to Build and Lead User Experience (UX) Teams

This article presents 9 guidelines for building and leading UX teams. They are based on what I learned from the people who led me as well as my own experience: recruit diverse talent; set up a process (and iterate); involve other teams from the start; be fair; have regular ceremonies; pass on knowledge; have a vision; ask questions (a lot); and make UX visible.

Jobs To Be Done in a Nutshell

The theory of Jobs To Be Done explains that too much focus on socio-demographic data and correlations hurts companies. Rather, you have to gain a deeper understanding of your customers, who "hire" your product to help them do certain jobs under certain circumstances. For instance, you don't buy a video game console because you're male and over 30. You hire it to, e.g., do the job "connect with friends".
