ALSC Usability Testing


An Electronic Health Record (EHR) application developed by Alert Life Sciences Computing, S.A. went through usability testing carried by CCG’s PIU team.

The tests were made in their real setting with end-users (physicians, nurses and system administrators), from the 29th of june to the 3rd july 2014 at the Tuba Regional Health Care Corporation in Arizona, USA.

These tests are called “Summative Usability Tests” and their application is advised for the later stages of product development, with an almost end version of the product. With the end-users of the product (1:1), the session moderator instructs them to perform some tasks that where carefully selected previously (eg.: frequent actions; potentially difficult actions), with the least amount of errors in the shortest amount of time. Some of the registered measures are the number of errors, time of execution, verbalizations and navigational patterns. The results allow to infer important information and valuable suggestions made by those who will actually use the product.

From these tests it is possible to point out critical areas of the product, as well as areas for improvement in what concerns the product’s good and efficient navigation.

The tests were made in order to obtain certification from the American entity "Office of the National Coordinator for Health Information Technology", with the intention of commercializing the EHR application in the American market.
