Measuring usability to optimize performance

Data Analysis

Measuring usability and knowing how to analyze the results is an integral part of optimizing our app performance and ensuring our customers are happy.

Here’s an example of how we measure usability and overall experience with our Oil Services Suite.

One of the tools we use to track ongoing usability is a survey called the UMUX-Lite. The Lite version we use is great because it’s only two questions, and they’re always the same regardless of whether we’re surveying about OpenInvoice, OpenTicket, Data Exchange etc.

UMUX-Lite Questions:

  1. The system’s capabilities meet my requirements.
  2. The system is easy to use.

Respondents rank agreement with these statements on a 5 point Likert Scale from “Strongly Disagree” to “Strongly Agree.” The 5 point rating system gives us a reliable way to calculate a numerical usability benchmark.

Despite being such a short survey (completed in less than 15 seconds) — the results give us a very reliable picture of perceived usability, and we can do it with a relatively small group of respondents.

Once we gather all the responses, we average the results and compare the top 2 boxes (somewhat agree and strongly agree) with the other three answers. We can then use the simple visual to get an at-a-glance look at our usability scores. We’ve done this same survey on our entire Oilfield Services Suite. Here’s an example comparing one of our newer Data Exchange products with an older (Legacy) version.

In the charts above the blue represents a combination of Top 2 scores, and you can tell that the newer software is scoring very well!

There’s a quick look at how we’re using input directly from the people using our software to make sure we continue to deliver the value we promise. As always, we welcome your ideas and feedback regarding any of our apps. If you’d like to help us out, please email us.
