Third Party Study Validates Industry-Leading Usability with Siemens Ultrasound Systems

May 17, 2016

· Newly designed systems earn high usability score in a third party study

· Simple, easy to learn user interface

· Average task completion rate of 95% with few deviations


Macadamian Technologies, a user experience research, design, and software development firm, recently announced the completion of a comprehensive usability test of Siemens ACUSON S3000™ ultrasound system, HELX™ Evolution with Touch Control1. The study was conducted at the request of Siemens Healthineers Ultrasound Business Area to measure users’ performance and satisfaction with Siemens’ premium family of ultrasound systems following the company’s concerted effort to improve overall system usability. The results of Macadamian’s usability test substantiate Siemens’ assertion of industry-leading usability with the ACUSON S Family, HELX Evolution with Touch Control.


The results from the study demonstrated that HELX Evolution with Touch Control is simple and easy to use, with a 95% average task completion rate and an overall average ease-of-use rating of 4.5 out of 5, where ‘5’ represents ‘very easy to use’. With a score of 83 out of 100 on the industry standard System Usability Scale Questionnaire, the system demonstrated excellent usability performance. Scores over 80 are considered well above average while scores below 60 tend towards poor usability. An average score is 682.


“We designed the HELX Evolution with Touch Control with the user in mind,” said Douglas Younger III, Global Segment Marketing Director, Siemens Healthineers Ultrasound. “The new platform is the result of intensive usability research conducted across four key regions and over 170 usability sessions. The results of this study show that this design is one of the most user-friendly ultrasound systems on the market.”


“As Siemens Healthineers, we are committed to listening to our customers and partnering with them to provide ultrasound solutions that improve outcomes, reduce costs, and expand the use of ultrasound,” said Said Bolorforosh, President of Siemens Healthineers Ultrasound Business Area. “These results prove that our systems can enable users to be more efficient and effective in their clinical routine.”


To further describe the methods and outcomes of this comprehensive study, Macadamian will host an hour-long live-streamed informational webinar on Thursday, May 19, 2016. During this session, Macadamian’s Senior Healthcare UX Researcher Anneliis Tosine, along with Anthony Sottile, Senior Staff Human Factors Engineer and Douglas Younger III from Siemens Healthineers will discuss the value of conducting comparative usability tests and the latest techniques for executing such a test.
