"Designers are architects of assumptions; success lies in the strength of the foundation built on user insights"
In the dynamic realm of User Experience (UX) design, assumptions are both inevitable and valuable. However, the success of a UX process hinges on the designer's ability to manage and leverage these assumptions effectively. This article explores the impact of working with assumptions in the UX process, strategies to avoid common pitfalls, the benefits of well-managed assumptions, and when it's appropriate to rely on them.
“Assumptions are the termites of relationships” - Henry Winkler.
This quote, while not originally intended for UX design, perfectly encapsulates the potential dangers of assumptions in the UX process. Assumptions, if not properly managed, can undermine the effectiveness of a UX design, leading to suboptimal user experiences
The Impact of Assumptions in UX:
Assumptions in UX design can negatively impact the user experience.
For istance, it might not always be accurate to assume that users are aware of what they need and how to reach their goals.
Misguided assumptions can lead to design failures by introducing risks and uncertainties into the design process.
Designers may base their product decisions on inaccurate or incomplete information when assumptions go unchallenged and unvalidated, leading to ineffective or irrelevant solutions.
Influencing Design Decisions: Assumptions often play a pivotal role in shaping early design decisions. For instance, when Apple assumed that users would embrace a touch-based interface with the iPhone, it revolutionized the smartphone industry. However, assumptions can also lead to missteps, as seen in the case of Microsoft's assumption that users would readily adopt the tile-based interface of Windows 8.
Statistic: According to a survey by NN/g, 52% of users said a bad mobile experience made them less likely to engage with a company.
User Understanding: Assumptions about user behavior, preferences, and needs can either align with reality or lead to a significant mismatch. Incorrect assumptions may result in a design that fails to resonate with the target audience, jeopardizing the overall success of the product.
"Assumptions are the sparks of innovation, but only user feedback can ignite the flames of success."
How to Avoid Assumption Pitfalls:
While it’s impossible to completely avoid assumptions, there are strategies to manage them effectively.
One approach is to make assumptions explicit. Once we know that different team members have different estimates of how big a task is, or how impactful or risky, we can discuss why. What do I assume differently from you? This usually highlights gaps in skill, knowledge, risks and much more.
Another strategy is to challenge assumptions. Gentle and open questions can help us probe deeper and uncover unconsidered perspectives. Questions like ‘So what do we not know?’ ‘How might this not be true?’ ‘What have we not considered?’ can help counter assumption with open questions and eyes-wide-open curiosity.
User Research: Conduct thorough user research to gather real-world insights. Airbnb, for example, transformed its user experience by embracing a data-driven approach. Through extensive research, they refined assumptions about user preferences, leading to a more personalized and engaging platform.
Statistic: Companies that conduct regular user testing see a 14.9% increase in conversion rates (Econsultancy).
Regular Testing and Validation: Constantly validate assumptions through usability testing and feedback loops. Slack, the popular collaboration tool, continuously refines its features based on user feedback, ensuring that assumptions made during the design process align with user expectations.
Example: Slack's iterative design approach saw a 25% increase in user engagement after implementing user feedback.
The Benefits of Well-Managed Assumptions:
Despite the potential pitfalls, assumptions can also be beneficial in the UX process.
They allow us to make quick decisions based on previous experience and generalizations.
This can be particularly useful in the early stages of the UX process, where there is often a high degree of uncertainty. Assumptions can help us prioritize effectively, although sometimes wrongly.
Accelerating the Design Process: In the initial stages of a project, assumptions can provide a starting point for design exploration. Tesla's ambitious assumption that electric cars could be both high-performance and stylish accelerated the adoption of electric vehicles in the automotive industry.
Statistic: Tesla's market value surpassed $1 trillion in 2021, showcasing the success of their assumption-driven approach.
Fostering Innovation: Assumptions can serve as a catalyst for innovative thinking. Google's assumption that a simple, fast, and accurate search engine was what users wanted led to the creation of the world's most popular search engine.
Example: Google's minimalist design and focus on speed contributed to its dominance, with over 90% of the global search engine market share (Statista).
When to Use Assumptions and When to Avoid:
The rule of thumb is that assumptions are set at the start of the process to filter out truths from them while facts should be dominating the segments near the end of the process.
Assumptions can be particularly useful during the ideation phase, where they can help generate a wide range of potential solutions.
Assumptions should not be used as a substitute for user research or usability testing. They should not be used to justify design decisions without proper validation.
And they should not be used to put company goals and technical limitations above user needs and preferences.
Appropriate Scenarios: Assumptions are acceptable in the early stages of ideation and concept development when concrete data may be limited. They can be used to generate hypotheses that guide further research and design exploration.
Statistic: 63% of companies believe that understanding user journeys is the most critical factor in delivering a good UX (Adobe).
Avoiding Assumptions in Critical Areas: Avoid relying on assumptions in critical aspects of the design, such as user needs, accessibility, and usability. Key decisions in these areas should be grounded in empirical data to ensure the best possible user experience.
"A well-placed assumption can be the key to unlocking creativity, but user validation is the locksmith that ensures a seamless fit."
Let’s look at some examples of working with assumptions in the UX process:
Poker Planning: An excellent example of how to work with assumptions is poker planning. This technique is used to estimate work and avoid anchoring to one guess. Discussing and working with assumptions can benefit the whole team, help to set realistic expectations and mitigate the risks for further work.
Medium: Contradicting the assumption that users prefer simple and minimal designs, we can use the well-known online publishing platform Medium as an example. With a variety of UI elements, animations, and functionalities, Medium’s design is anything but minimalist. With a simple and intuitive navigation system, the design remains highly user-friendly and enables users to find and interact with content with ease.
Statistics
Statistics show that assumptions can have a significant impact on the UX process.
For example, the null hypothesis is the default position. In our example, the default position would be the assumption that there is no difference in the aesthetic appeal of the two images. Statistically speaking, the default position is called the null hypothesis and its symbol is H03. And the symbol for sample mean or average is μ (mu)3.
Conclusion:
Working with assumptions is an inherent part of the UX design process, but their impact depends on how they are managed and validated. By incorporating robust user research, regular testing, and a user-centric mindset, designers can strike a balance between leveraging assumptions for creative exploration and ensuring that their designs are grounded in reality. Ultimately, the ability to navigate the delicate dance of assumptions is a hallmark of a successful UX designer, contributing to the creation of products that genuinely resonate with and delight users.
