Persona

Provide 3 pieces of constructive feedback that could help the app to be better suited to the scenario it was designed for Overall, the app is comprehensively designed for its usage. Here are some minor suggestions:

• The marker for the year 2016 is missing, and therefore a member of the Olympic committee might assume that the data for that year’s Olympics is missing.
• The median of the distributions can be displayed on the plots as a general user may be more interested in a quick summary
• An option to include all the total number medals winners (e.g ‘all medals’) in addition to the count of all competing athletes will be useful

Provide 3 pieces of constructive feedback that could help the app to be better suited to the user(persona) it was designed for

• A little summary can be included below the heading of the plot to explicitly state that the count of medals on the chloropleth map is by athlete and not by sport so that the user does not get confused.
• Usually a general user, such as the persona, will be more interested in the distribution of medals than the details of the athletes. Therefore it might make more sense to place the chloropleth on top .
• A dynamic heading at the top of the dashboard can be used to indicate the years the plots are being displayed for explicitly.

Frontend / layout Is the text (plot labels / titles / subtitles) easy to read?

• Yes, the text is easy to read.

Are the plots selected appropiated for the data? Can you think of other alternatives or improvements for the plots regarding interactivity/reactivity or plot selection?

• I think the plots are appropriate. We can clearly see the bimodal distribution between males and females. The map provides a good insight into location distribution. One thing can do better is fixing the scale of the map.

Was the dashboard organized in a way that was easy to read (columns / rows) or you would suggest a change in this sense?

• It is easy to read and understand. The color can be more Olympics 5 color themes tho.

Would you prefer including tabs / navbars to improve the navigation or you think it is better to visualize everything in one screen by the nature of the content?

• I would use a slide bar instead of a slide range. I prefer to look at the trend throughout the year instead of a range since the Olympics has a natural 4 years window. Maybe adding animation if time is sufficient but not necessary.

Are the plots or other images described properly for the persona described?

• The plots and images are very relevant to both casual sports enthusiasts or members of sports committees. The layout of the plots and the general theme of the dashboard deem it agnostic to either use. Perhaps the use of the purple background can be made to white, and an olympic logo can be incorporated to further streamline the design to the Olympic theme which the persona may expect.

Backend Are the options that you can select in the widgets working fine or have you found some cases where it is not working?

• In most of the cases, the graphs are working normally. However, when I select some specific combination with no available data, such as Alpine Skiing in Summer Olympics, empty graphs would be produced.
• To address the above problem, I would suggest showing error message to the user to make the dashboard more user-friendly.

If there are interactive plots: are the labels clear and easy to understand?

• The histograms are interactive, that it allows users to zoom in by selection and toggle the category of data by clicking on the legend. However, there is no explicit instruction nor description about the feature.
• On the other hand, it is much appreciated to have reminder messages to tell user that the zoom could be resumed by double click when a graph is zoomed in for the first time, as well as when the legend is toggled.

Documentation Was the documentation easy to understand from the README.md how to use the app? How could the documentation be improved?

• The document is easy to understand. Clearly states what should I expect by categories for problems and solutions. The gif in the demonstration session is pretty buried. It doesn’t serve its purpose fully =[

Was the app intuitive to use without reading the documentation? What information could be good to include?

• I played around with the dashboard before reading any documentation, No problem at all. I think if you have some logo/ Olympic colors, people will understand the theme of the dashboard at their first sight.

Indicate something you would like to include in your own app after reviewing this one

• The use of the loading animation can be incorporated into our design, especially as it indicates to the user that there is an expected output after filtering

Hi @PhilsChan ,

Thanks for your constructive feedback. Just wanted to provide some of our responses to your feedback.

1. As suggested, we have moved the demonstration section in the Readme file to the top to better serve its purpose.
2. We have also include an Olympic logo as our Favicon. Hopefully, the user could get a better idea about our application in the Olympic games context.

I believe Cuthbert @cuthchow will address those feedback for the dashboard/application aspects in our next deployed version in Milestone 4. We look forward to it!
