Basketball is almost the complete opposite to baseball and softball in terms of complexity and pace. When a player scores, the only information that needs to be recorded is where the shot was made and by whom. Some coaches might also be interested in recording assists. When compared to baseball, the flow that a scorekeeper has to go through is a lot shorter, and yet users often find it difficult to score a game without falling behind.
The reason is that basketball is a very fast sport. Many things can happen in a span of seconds and all of them need to be recorded in order to obtain accurate stats. Taking this into account, the GameChanger app attempts to make scoring a basketball play something very quick. Buttons are bigger and options are limited. Furthermore, the app allows the user to check and correct previous plays. What this means is that users know they can continue to pay attention to the game, and when they have a chance they can go back and assign a shot or a foul that was recorded earlier. This helps reducing the potential stress caused by failing to record some of the plays.
Despite these efforts, basketball scorekeeping is still too hard for some users. Scoring plays needs to be even faster. This can be achieved by attempting to predict how users behave when using the app, and optimizing the user interface for that behavior. There are tools that can be used for that purpose such as CogTool, which allows the design and testing of different storyboards by predicting how skilled users would perform on them while doing different tasks.
Every change made to the current interface involves some risk, given that it’s hard to anticipate if users will understand the new interaction models. That is why using a rapid prototyping methodology becomes really important, as it provides early feedback from users. This involves iterating really quickly over some UI concepts, and testing them in office with actual users. After the tests are conducted and analyzed the team is able to decide what works and what doesn’t, and develop the next prototype for a new round of user testing. As an engineer, this has been a great opportunity for me to get direct contact with users and understand how they perceive and use the app, which I think is really important for being able to make a successful product that actually provides a great value to people who use it.
Understanding how the differences between sports affect what users need from the app, is very important for providing a successful experience. This will become harder and even more important in the future as new sports are introduced, because each one of them will bring new challenges that will need to be addressed. To do so successfully, it is very important to maintain a close relationship with coaches and scorekeepers, as GameChanger has done so far, since this is the foundation for understanding what they really need from the product and what the best user experience should be.
