Why Good Usability Is Key to Success or Failure Today

Good usability is not a “nice-to-have,” but critical to success. In a digital world where alternatives are just a click away, it is no longer just the product range that determines success, but the quality of the user experience. Today, users not only compare companies within an industry, but also measure every digital experience against the best experiences they have had anywhere: fast processes, clear orientation, smooth workflows.

The problem: even a single negative experience can be enough to lose users permanently—often without ever receiving clear feedback. Three figures show how quickly usability problems can become a business risk:

• No second chances: According to PwC, 32% of customers would abandon a brand they actually like after just one bad experience.
• Lost users: 88% of online consumers are unlikely to return after a negative website experience – serious usability problems therefore cause a large proportion of potential customers to abandon the site at a critical moment.
• Silent dissatisfaction: 91% of dissatisfied customers do not complain—they simply disappear without comment.

These figures make it clear: poor usability is often a silent revenue killer. The symptoms are indirect: rising abandonment rates, declining conversion, increased support costs, poorer ratings, declining usage frequency, or rising churn rates. In many cases, these effects are initially misinterpreted—for example, as a marketing problem, a pricing problem, or general market saturation. In reality, it is often a usability problem in the core process.

Conversely, a good user experience creates growth. When users reach their goal smoothly, they feel secure, competent, and understood. This not only increases the likelihood that they will complete a purchase, but also that they will return and recommend the site to others. This is precisely where the leverage lies: usability is not just “design,” but has a direct impact on trust, brand perception, and economic success.

The key challenge is therefore to identify usability problems early on—before they manifest themselves in declining key figures and lost users.

Why Digital Products Fail Despite Investment

Many companies invest considerable sums in relaunches, new features, or design overhauls. Nevertheless, the expected effect often fails to materialize—and sometimes even the opposite occurs: conversions decline, support tickets increase, existing users are annoyed, and the team works in crisis mode. The reason is rarely “the technology.” Often, it is a lack of user centricity.

When a digital product relaunch fails, it is almost always because the concept and decisions were not sufficiently aligned with actual user behavior. Typical patterns:

1. Existing usage is not systematically understood.

Instead of analyzing which paths users actually take, which functions are critical for existing customers, and which mental models have become established, a “new way of thinking” is adopted right away. This destroys routines, habits, and implicit expectations—often without anyone noticing.

2. It is being developed “on sight.”

Many relaunches are based on internal assumptions, design trends, or subjective opinions. These may seem consistent within the team, but they are no substitute for evidence. Without genuine user research, it remains unclear what users really need, how they interpret terms, or why they abandon certain processes.

3. Aesthetics dominate user guidance.

“Modern” and “clean” can look good, but they can also reduce information density, make orientation more difficult, or hide important information. Often, a lot of effort goes into visual design, while navigation logic, interaction feedback, error messages, and content comprehension are not tested sufficiently.

4. Tests arrive late or not at all.

If testing is only carried out shortly before go-live, there is little scope for fundamental adjustments. Symptoms are then “fixed” instead of causes being resolved. And if no testing is carried out at all, the launch is a predictable risk.

The consequences are costly: undesirable developments, missed targets, long-term loss of trust and, in the worst case, a product that performs worse after the relaunch than it did before.

Real Examples, Real Consequences

Well-known cases from various industries show that these mechanisms are not theoretical:

Marks & Spencer (2014): The British retailer invested around £150 million in a website relaunch. The result: online sales fell significantly within a short period of time. The design was “magazine-like” and modern – but many users found it difficult to navigate and were unable to reliably complete the checkout process. Lesson learned: attractive does not necessarily mean understandable.

Deutsche Bank “Maxblue” (2016): The redesign looked contemporary, but ignored a key need of existing customers: a quick overview. Instead of efficiency, friction arose, and the feedback was clear: many wanted the old watch list back. Insight: Existing users differ fundamentally from new users.

Schlecker online shop (2011): Modernized, but fewer products visible, fewer price signals, poorer price perception. A target group that was heavily dependent on bargains and guidance no longer felt catered for. Insight: User intention is not automatically designer intention.

A typical statement from projects is: “We have invested a fortune in the redesign – and now we have significantly fewer orders than before.” Such slumps occur when user guidance, expectations, and habits have not been validated. Internally, the change appears to be an improvement – but once live, it becomes a change for the worse.

The Solution: The Quick Check for Usability Evaluation

This is where the Quick Check from msg.passbrains comes in. It is a compact, practical usability test conducted under realistic conditions: real users test the product on real devices in real-life situations – and provide reliable feedback that can be directly translated into product decisions.

The goal is not to “fully evaluate” a product as in studies lasting months. The goal is to clarify the crucial questions in a short period of time:

• Where do users fail in the core process—and why?
• Which obstacles seem small but have a big impact?
• Which elements are unclear, ambiguous, or generate mistrust?
• Which optimizations bring measurable effects in the short term (quick wins)?
• Which topics should be addressed strategically to ensure long-term UX quality?

The Quick Check provides:

• realistic insights instead of internal assumptions
• Early indications of usability issues, functional weaknesses, and gaps in understanding
• Prioritized recommendations for action – from quick wins to strategic UX measures

It is important to manage expectations: the Quick Check identifies risks and problems. It does not automatically ensure that these disappear—but it creates the basis for targeted optimization instead of guesswork.

What is being tested? The Six Focus Areas in Detail

1. Accessibility and Entry

The onboarding process is often the most underestimated area—yet it determines whether users even have a chance to experience the value of the product. Here we examine: How clear is the start? Are login, registration, or first steps understandable? Are users overwhelmed with too many options? Is content accessible? Can users quickly find the right entry point for their intentions? Often, it becomes apparent here that it is not the functions that fail, but rather orientation, language, and expectation management.

2. Navigation and Usability

Navigation is more than just menu structure. It's about mental models: Do users understand where they are, how to get back, and how to reach their destination? Is the operating logic consistent across pages? Are interactions clearly confirmed? Are there any dead ends? These are common points of friction that no one internally notices because the team knows the structure by heart.

3. Core Features

This is where business impact is determined. Core functions are the tasks that users came for in the first place: buying, booking, transferring money, configuring, managing, comparing. If there is confusion, error messages, or unnecessary steps, this leads to cancellations, support requests, or mistrust. The Quick Check not only checks whether users “somehow reach their goal,” but also how robust and understandable this path really is.

4. Content and Presentation

Very often, it is not the UI elements but the content that causes problems: terminology, wording, unclear labels, overly complex text or a lack of explanations. In this area, we check whether the content is understandable, whether the information architecture is logical, whether prioritization and reading guidance work, and whether the tone is appropriate for the target group. Often, small text adjustments are enough to achieve big effects.

5. Performance and Stability

Even the best UX fails if loading times interrupt the flow. Users interpret performance not technically (“server load”) but emotionally: “This is slow” becomes “This is unreliable.” The Quick Check therefore looks at loading times, stability, error messages, and behavior on different devices. Especially with mobile use, performance can be the deciding factor between completion and abandonment.

6. Overall Impression

In the end, it's all about perception: Does the product seem trustworthy? Does it feel clear, stable, and logical? Would I use it again? Would I recommend it to others? This is exactly where loyalty—or churn—comes into play. The Quick Check reveals how users rate the product as a whole and what factors influence this assessment.

What happens during a quick check? The Process in Practice

A quick check is a streamlined version of the usability test process—it gives you the most insight in the least amount of time.

1. Recruit Real Users

The crucial point is accuracy of fit. Users are recruited who correspond to the target group—based on criteria such as experience, usage behavior, demographics, or context. It is important that they ideally test on their own devices, because this creates real-life conditions.

2. Designing Test Tasks

The tasks are based on real use cases, typical journeys, and known pain points. They are deliberately formulated in an open-ended way so that users can follow their own path—because it is precisely these paths that reveal where product logic and user logic diverge.

3. Implementation and Monitoring

Remote, pragmatic, and efficient—for example, via questionnaire, screencast, or short recording. The focus is on observability: Where is there hesitation? Where are incorrect clicks made? Where do questions arise? Where is frustration visible? In addition, subjective assessments are recorded (difficulty, clarity, satisfaction).

4. Evaluation and Pattern Formation

Results are consolidated: recurring problems, patterns, and drop-off points are identified. Often, just a few test endings are enough to identify robust patterns—not as statistics, but as clear indications of structural UX problems.

5. Result Preparation and Prioritization

The findings are presented in a structured, comprehensible, and action-oriented manner. Prioritization according to severity and impact is crucial: What does conversion cost? What is blocking progress? What is merely “unattractive” but not critical? Strengths are also noted so that teams know what should be deliberately retained.

What Makes the Quick Check Special: Speed and Accuracy

The Quick Check is not a substitute for large research programs—it is a tool for making quick, informed decisions. Within a few days, it provides insights that would otherwise often only become apparent after weeks or after launch. The proximity to reality is created by real devices, real usage contexts, and real perspectives. This also reveals factors that are missing in the laboratory: distractions, different displays, performance on older devices, interpretations of terms, or behavior in “non-ideal” situations. It is precisely these “imperfections” that are crucial in everyday life.

The Impact of the Quick Check: Lower Risk, Higher ROI

A quick check offers concrete economic advantages:

1. Early Problem Detection

Problems become visible before they cause damage in production. This reduces follow-up costs, crisis fixes, and support efforts.

2. Real User Perspective Instead of Gut Feeling

Teams make decisions based on evidence. Often, it's small adjustments that have a big impact—e.g., a label, an order, a hint, a feedback text.

3. Avoiding Relaunch Disasters

Quick checks act as an early warning system. They can show whether a relaunch violates key expectations—before conversion and sales plummet.

4. Increase Satisfaction and Business Success

When users reach their destination faster, the likelihood of completion, return visits, and recommendations increases. At the same time, negative effects such as abandonments, support tickets, or poor ratings decrease.

5. Fast Return on Investment

The effort involved is relatively low, and the findings can be put to immediate use. Many improvements can be implemented quickly—with measurable results.

Conclusion: Quick Checks Reduce Risk and Create Clarity

If you take one thing away from today, it should be this: user feedback is not a luxury—it is a key success factor. A relaunch alone does not guarantee success. Without genuine validation, it can even become a risk. With a quick check, you reduce this risk because you gain real insights from the user's perspective at an early stage. This saves time, money, and nerves – and ultimately increases your return on investment. And most importantly, satisfied users not only stay, they recommend you to others. Users become promoters. This is precisely one of the strongest growth drivers for digital products.
