- This design has good learnability because there are few options and the process is very compact. You can log onto the site and have a QR code created in less than 60 seconds depending on the speed of your browser. This makes it very efficient. A user visiting the site for the first time can click on the make a QR code button and start entering information right away.
- Viewing the results is easily visible when you login and the results are clearly indicated making it easy and efficient for the data collector to deal with.
- This design could be improved by adding an edit QR code option. It is unsafe because if you make an error and create the code, there is no option for going back and editing the code, you have to start over. This is unsafe and could be made better by simply saving the form of the QR code and allowing the poster creator to go back and edit the details of the event and create an update QR code.
- This design lacks any help information, which suggest some bad learnability. If a user gets stuck at some point, there is no help features to point them in the right direction or lead them to the next step. This could be fixed by simply adding a button 'The Next Step' that, an any point in time, offers suggestions as to what the next step in the process should be or normally is. This will help with learnability for new users that have no idea what to do.
- There is no way to delete an event. This is good for safety but bad for efficiency. The user will never be able to get rid of an event that they created, meaning that they will never lose any of the data they wished to collect. However, this also means that, updated or corrected events will be named in a confusing manner. Thus, leading to description errors and decreasing the safety of the site. This could be improved by allowing a user to delete an event. The user should have to enter their password and verify the deletion in order for in to occur, so as to not delete an event by accident.
- Lacking the ability to delete event means the number of events in your history will continue to grow forever, which is terrible for efficiency. If you wish to view an event in the past in may take a very long time to find it. This can be fixed by adding a search box for the events to help narrow down the number of events you have to physically look through when trying to find a particular event. The search box could be based on other parameters as well to make it easier to find said events, such as: date, type, and location.
