Understanding the Fundamentals of a Bad User Interface and Why It Matters

Creating a well-functioning user interface (UI) is a complex process that requires a deep understanding of user behavior, design principles, and the technical aspects of software development. Few qualities contribute as much to a bad user interface as the absence of proper on-screen guidance and the non-use of standard resources within the system. This article delves into the reasons behind bad UIs, the business attitudes that lead to their creation, and the importance of focusing on user-centric design.

What Constitutes a Bad User Interface?

There are several factors that can make a user interface bad, none of which can be exhaustively listed. As a user experience (UX) designer, I’ve encountered and discussed numerous bad examples on my blog. However, rather than focusing on negative examples, it’s more productive to concentrate on what makes a user interface good. Designing something that is intuitive, consistent, and aligned with user expectations is key.

A good user interface should be clean, consistent, and clear. It should align with user behaviors and expectations, and it should effectively meet the needs of its users. The goal is to provide the best user experience possible, without being obnoxious or overly subtle.

Lack of On-Screen Guidance and Inefficient Use of Built-In Resources

One of the most significant issues with user interfaces is the lack of on-screen guidance. For instance, the control keys in MS/PC DOS, such as Ctrl-A through Ctrl-Z, are powerful tools that have been standard in user interfaces for decades. Even better is the use of resources built into the system, like keyboard templates in applications like WordPerfect, which provide a convenient and efficient way for users to interact with the software.

Replacing these standard resources with proprietary or less convenient alternatives is a step backward in user interface design. For example, the Microsoft Word 1.01 through 2.xx versions and WordPerfect both had keyboard templates that helped users navigate and edit documents more efficiently. However, any attempt to replace these with less convenient proprietary resources is detrimental to the user experience.

The history of user interface design shows a decline in standards since the introduction of applications like WordStar. While progress is made, there are still many cases where user interfaces fall short of providing a seamless and intuitive experience.

Business Attitudes and the "We Don't Have Time for That" Mentality

The business attitude that leads to bad user interfaces is often linked to a lack of time or resources for user-centric design. The phrase "We don't have time for that" commonly appears when discussing user interface improvements, implying that user experience is secondary to other goals. This mentality often stems from concerns about software development 'cycle time' and maintaining investor confidence.

Development teams might feel pressure to keep their processes lean in an effort to address waning investor confidence. However, this attitude can lead to what is known as usability debt. Usability debt occurs when the design and user experience are compromised in the short term to meet a deadline, resulting in a product that is difficult to use in the long term. This debt is often not fully realized until later, when it may be brushed off or addressed with plans for future releases.

What Makes a User Interface Good?

A good user interface is the result of a deep understanding of user behavior, requirements, and design principles. This includes a combination of interaction and visual design, combined with diligent technical implementation. The process of creating a good user interface involves significant effort and is often at odds with the prevailing belief in agile development, which often prioritizes speed over meticulous design.

Insight into user behavior, clear requirements definition, and design thinking all play crucial roles in creating a good user interface. Best practices from interaction and visual design, combined with technical craftsmanship, are essential. User interfaces that are well-designed and well-implemented provide a superb user experience, which is the ultimate goal of any software project.

Conclusion

A poorly designed user interface is more than just a flaw; it is a reflection of a broader business attitude that can lead to significant usability debt and a subpar user experience. By focusing on user-centric design, understanding user behavior, and implementing best practices, we can create interfaces that are intuitive, efficient, and enjoyable to use.
