Does the NPS predict growth? What data is there to support the predictive ability of the Net Promoter Score? In the original research reported by Fred Reichheld, he showed that the NPS strongly correlated with growth in 11 out of 14 industries. However, he used historical, not future, growth. While this established a sort of concurrent validity, it left open the question about the predictive

Should you label all points on a scale? Should you include a neutral point? What about labeling neutral points? How does that affect how people respond? These are common questions when using rating scales and they’ve also been asked about the Net Promoter Score: What are the effects of having a neutral label on the 11-point Likelihood to Recommend (LTR) item used to compute the

We talk a lot about measurement at MeasuringU (hence our name). But what’s the point in collecting UX metrics? What do you do with study metrics such as the SUS, NPS, or SUPR-Q? Or task-level metrics such as completion rates and time? To understand the purpose of UX measurement we need to understand fundamentally the purpose of measurement. But settling on a definition of measurement

Have you recommended a product to a friend? Will you recommend that same product to a friend again? Which of these questions is a better indicator of whether you will actually recommend a product? If people were consistent, rational, and honest, it’s simple. The second question asks about future intent so that would be the logical choice. It may come as no surprise that people

Booking a flight online involves more than selecting two cities and departure times. Airlines have given consumers many more choices when booking a flight. Do you want: Economy, basic economy, sub-basic economy? 2 bags, no bags, 1 carry on, no carry on? Board early, board late? Pick a seat, get assigned a seat? Each choice requires a decision and has a cost implication. In fact,

For measuring the user experience, I recommend using a mix of task-based and study-level measures that capture both attitudes (e.g. SUS, SUPR-Q, SEQ, and NPS) and actions (e.g. completion rates and times). The NPS is commonly collected by organizations and therefore UX organizations (often because they are told to). Its popularity inevitably has brought skepticism. And rightfully so. After all, the NPS was touted as

It seems like each year introduces a new measure or questionnaire. Like a late-night infomercial, some are even touted as the next BIG thing, like the NPS was. New questionnaires and measures are a natural part of the evolution of measurement (especially measuring difficult things such as human attitudes). It’s a good thing. I’ll often help peer review new questionnaires published in journals and conference

Have you taken a survey for a company without an incentive? I mean surveys where you have no clear chance of winning a prize, getting a discount, or receiving any clear compensation for your time? If you did, what motivated you to take it? Were you just curious, maybe killing time? Did you have a more positive or negative attitude toward the product or company

Does better usability lead to more revenue? What about positive word of mouth? Is it tied to revenue growth? Are UX metrics for usability and intent to recommend able to track future revenue growth? Many UX researchers who work for software companies or on software products collect UX metrics. In fact, we strongly advocate for it. As part of implementing a plan to improve UX,

Public officials don’t care much about what the general public thinks. Voting is the only way ordinary people can have a say in government. How much do you agree with those two statements? If the order in which those items were presented were switched, would it affect how you responded? While most UX and customer research doesn’t involve sensitive topics, does the order in which
