UXDD (User Experience Driven Development): Build For Your Users, Not Your Tests

Ted O'Meara • August 16, 2012 • Earth

In his presentation at the MountainWest RubyConf 2012, Ted O'Meara emphasizes the critical importance of focusing on user experience (UX) in software development rather than just the automated testing process. While automated tests are valuable for ensuring functionality, they often do not capture the nuances of user interactions. Developers are encouraged to step back from their coding routines and assess the user experience to create more effective applications.

Key points discussed in the video include:
- User Experience Focus: The talk opens with the assertion that developers must prioritize the experience of end users over the pursuit of passing automated tests, which can lead to products that meet technical specifications but fail to resonate with users.
- Psychology and User Interaction: O'Meara discusses the influence of human psychology on UX and suggests that developers need to keep this in mind when creating applications.
- Deficient Requirement Handling: A significant issue arises when team members do not thoroughly read and understand requirements, resulting in products that fail to meet user needs.
- Communication and Planning: Increasing collaboration during the planning phase of development is vital. O'Meara advocates for including input from all team members to ensure a comprehensive understanding of user flows and visual design documents.
- User Stories Importance: The use of user stories is framed as essential for clarifying how users will interact with applications. These narratives help transform business logic into functional features.
- Visual Regression Testing: The speaker introduces visual regression testing as a strategy to maintain UI consistency and user-friendliness throughout the development cycle. Automating the testing of user interfaces helps in identifying discrepancies early.
- Real-World Examples: O'Meara references platforms like MySpace, underscoring how neglecting user experience can lead to failure. A lack of proper evaluation of the user journey results in a product that does not fulfill its potential.

In conclusion, O'Meara encourages developers to embed user experience into every phase of the development process. By prioritizing user engagement and satisfaction, teams can create more successful applications that truly meet the needs of their users. Overall, the focus should shift from solely achieving functional completeness to cultivating a polished and user-friendly product.

Ted O'Meara • August 16, 2012 • Earth

All too often programmers get into a productive rhythm where they receive their requirements, write tests aligned to those requirements, and then look for the green and red. While this process is proven to be highly effective, it can lead to developers missing the mark, as they aim for functional completeness and not the polish that an end user requires.

We should start proposing breakpoints for developers to step away from their automated tests, and play with the features they are working on. It's too easy for developers to get caught up in their process and forget about the end user experience. In this presentation you will learn several techniques for developing for the user experience, even when you're buried in code.

00:00:17.580 Hello everyone, my name is Ted O'Meara. Today, I want to talk about the importance of user experience in development.
00:00:20.770 It's crucial that we focus on building better experiences for our users and not just investing time in automated tests.
00:00:27.820 In this talk, I will cover various aspects of human psychology that relate to user experience, and how that influences us as developers.
00:00:34.930 We often have these ideas from clients for greenfield applications, and while that’s great, it’s important that we don’t lose sight of our end users.
00:00:41.129 What I’ll discuss today might not perfectly apply to your product, but it will give you some insights into how to structure your approach.
00:00:43.630 While we all love tests, sometimes they don’t help us create the best user experience. They can give us confidence, but they don’t always result in the best user interactions.
00:00:56.820 A lot of times, requirements are not read thoroughly, and the result is a product that does not meet the user's needs.
00:01:09.370 We need to embrace better messaging and visuals to ensure we don’t overlook the importance of user experience.
00:01:18.910 As humans, we look for visual patterns. Even as developers buried in code, we need to remember that we’re ultimately creating experiences for people.
00:01:31.610 Bad tests can lead to poor user experiences, and we must consider the validity of what we create.
00:01:43.390 Critique your output and see how these ideas of user experience can drive better design. We shouldn’t simply trust a design process blindfolded.
00:01:55.040 For example, take a look at platforms like MySpace that suffered due to neglected user experience. It wasn’t just a matter of missed features but a failure to properly evaluate the entire user journey.
00:02:09.310 When teams don’t clearly define requirements throughout the agile process, they can easily miss the mark, leading to a poor user experience.
00:02:29.160 I believe we can significantly improve by overlapping planning and execution phases. Planning should not be siloed away but should include input from all team members to enhance communication.
00:02:49.079 During the planning phase, we should create user flows and wireframes. These visual documents can act as a required guideline for the development process.
00:03:01.609 By detailing how a user should interact with an application, we can identify what needs polishing rather than just meeting the bare minimum.
00:03:18.069 When we talk about user stories, they serve as narratives that help us understand how our users interact with the system. They are critical in creating a good user experience.
00:03:37.030 User stories allow us to translate business logic into functionality and create clear expectations of what users should be able to do.
00:03:51.399 However, we also need to recognize that what happens if users encounter unexpected issues or interface changes. This means we have to design for usability from the first moment.
00:04:13.490 Moreover, I propose using visual regression testing as a way to ensure our interface remains consistent and user-friendly over time.
00:04:37.570 We should aim to create automated tests that validate user interfaces rather than relying solely on backend tests that may miss front-end issues.
00:04:59.299 Consider tools that allow us to compare screenshots and check for discrepancies in our UI; this can save time and resources.
00:05:05.300 Automated testing frameworks can help us to verify that our changes reflect the intended design and functionality.
00:05:32.310 Engaging in this practice can make us aware of potential flaws while making improvements. It ensures a smoother user experience.
00:05:55.620 Let's embrace the importance of visual testing and ensure our applications cater to user experience first. Doing so will ultimately lead to more successful applications.
00:06:12.380 In conclusion, prioritize your users in every step of your development process. By doing this, your applications will be more successful and meet the needs of the user.
