## 6 Usability Study Result  
We managed to conduct a small-scale human subject study on the usability of our web application. Three individuals experimented with entering the daily update of wait time and availability. Two individuals experienced the registration process. Three individuals tried out our web application to search for aftercare for their clients. All eight participants are 30 to 50 years old female employees at a hospital. Below we summarize their opinions regarding the questions we have asked. For each question, we asked the participant to give an opinion in a scale of 1 to 5, with 5 being the most favorable.  
Question 1: _For the treatment service search functionality, do you agree that the filtering criteria are adequate?_ All of them rated 5. However, they did suggest adding some criteria for filter, and we will be adding them for the next release of our application.  
Question 2: _For the treatment service search functionality, are you happy with the quality of the search result (i.e., the most desirable result is up front)?_ All but one person gave a 5 rating. The one person who rated a 4 thought that the languages used for the website were too technical.  
Question 3: _Regarding the daily update of the available services, how do you rate the helpfulness of the daily email reminder and the direct link to the update page?_ All participants rated 5. They said that the update is easy and they do not have anything that they think we should change.  
Question 4: _Regarding the input process of the services/treatment, how do you rate the helpfulness of the progress bar?_ This feature received lower ratings (3 and below) because the progress bar shows incomplete when the agency left some sections blank because such sections do not apply to the agency. We will add an option for \"not applicable\" to solve this problem for the next release of our web application.  
Question 5: _If you have experimented with accessing our web application using a mobile device, how do you rate the UI design (ease of access to information and data input)_? All participants gave a 5 rating. They all liked the mobile interface. It is virtually the same as the desktop web interface, except that the filter shows up at the top.  
Question 6: _If you have experimented with accessing our web application using a desktop/laptop computer, how do you rate the UI design (ease of access to information and data input)_? All participants rated 5. They thought that the website is much easier and straight forward to use compared to other websites with similar services. The only one \"complaint\" was that the particular hospital used an old Internet Explore browser, which did not work well with the website, so they had to use Google Chrome instead. There is nothing we can do about this.  
Question 7: _What is your overall rating for the usability of our application?_ All but one gave a 5 rating except the one person who gave a 4 rating because she deemed the application too technical. However, we think she misunderstood our project. We explained that the current phase of the web application is meant to be used by medical professionals, and we are currently developing another one for use by the general public.  
As can be seen from the result, the web application is well received in general. We did find one area of improvement on the progress bar design, which will be fixed for the next release of our web application.
