Visual design in data analytics
If you search for books or YouTube videos on Power BI, you’ll find plenty of options to learn DAX, M, data modeling, and tricks to make interesting visuals. While some resources touch on design, they often miss the crucial fundamentals necessary for creating scalable and effective designs. A typical program or degree in business analytics might gloss over or completely evade this topic. Design is often an afterthought for many analysts, who believe simply getting the data on the canvas is “good enough.” But is it really good enough? Experience has shown that when report authors place visuals haphazardly on the canvas, it leads to numerous user questions and confusion, bogging down analysts and causing churn around numbers, accuracy, and calculation logic.
At its core, data analytics is about communication. So, why don’t we focus more on one of the most crucial aspects of communication: visual design? Scalable design is essential for ensuring consistency and professionalism across multiple reports and dashboards. I’ve been working with Power BI since its release. It’s an incredibly powerful tool, and it’s very rewarding to learn and implement solutions using it. However, many Power BI reports (including some of my own early on) struggle with one major issue: they lack good design. I don’t blame analysts for having poorly designed reports; often, they don’t have the bandwidth to spend time on design improvements amidst urgent requests. But over time, this pattern of publishing reports with little concern for design can lead to user confusion and make the entire reporting environment look unprofessional and low quality, ultimately decreasing overall trust in the data. This is what we call design debt.
Design Debt
Design debt, also known as user experience (UX) debt or product design debt, refers to the accumulation of design issues or suboptimal design decisions that arise when short-term solutions are prioritized over long-term, high-quality design practices. It is similar to technical debt but focuses on design and user experience aspects rather than purely technical concerns.
Design debt is a recognized challenge in professional design and web development, but the issue can become significantly more pronounced in environments like Power BI. This is because the primary users of Power BI are analysts who often have little to no formal design training. This environment creates a perfect storm for the rapid accumulation of design debt.
Power BI users are typically analysts who are experts in data analysis, not design. Their primary focus is on data accuracy, insights, and reporting, not on design principles. Most analysts have minimal exposure to design best practices, which means they are less likely to recognize design debt or know how to address it effectively.
Inconsistent visual styles are a common source of design debt in Power BI. Without a strong understanding of design consistency, analysts might create reports with varying color schemes, font choices, and visual styles, leading to a disjointed user experience. Poor layout and user flow are also prevalent issues. Analysts may prioritize data density over readability and user flow, resulting in cluttered, confusing reports that are difficult for end-users to navigate. Accessibility considerations are often overlooked, making reports less usable for people with disabilities. Under pressure to deliver insights quickly, analysts might implement quick fixes and workarounds that solve immediate problems but introduce long-term design debt.
The impact of accumulated design debt can be severe. Reports that are hard to read, navigate, or understand can frustrate users, reducing the perceived value of the insights provided. Design debt leads to higher maintenance costs as reports require frequent adjustments and redesigns to address usability issues. Poorly designed reports can lead to lower adoption rates, as users may prefer alternative tools or methods to obtain the insights they need. Without a coherent design strategy, reports may suffer from inconsistent branding, undermining the professional appearance and credibility of the reports.
Design Systems
Given the significant risks associated with design debt in Power BI, it becomes essential to implement strategies that can mitigate these issues. This is where design systems come into play.
What is a design system?
A design system is a comprehensive set of guidelines, components, and standards that ensure consistency and coherence across all design elements within a product or suite of products. By establishing a robust design system, organizations can provide Power BI users with the tools and best practices they need to create visually consistent, user-friendly, and accessible reports. This approach not only reduces the accumulation of design debt but also enhances the overall quality and usability of analytical outputs.
What to look for in a design system
To effectively manage design debt and ensure a cohesive user experience, implementing a design system is crucial. A well-crafted design system provides a structured approach to design consistency and efficiency, encompassing several key components. These components include:
- Design Principles: Foundational guidelines that articulate the core values and philosophies guiding all design decisions, ensuring alignment with the desired user experience and brand identity.
- Style Guide: Detailed visual elements such as a predefined color palette, typography guidelines specifying font families, sizes, and weights, an icon library maintaining consistent style and scale, and spacing and layout guidelines for uniform margins, padding, and grid systems.
- UI Components: Reusable user interface elements like buttons, modals, and navigation bars, designed to be used consistently across different parts of the product, promoting a cohesive user experience.
- Design Tokens: Variables for storing design decisions such as colors, fonts, and spacing values, which help maintain consistency and enable easy updates.
- Pattern Libraries: Predefined combinations of UI components that solve common design problems, enhancing design efficiency and coherence.
- Documentation: Comprehensive usage guidelines, best practices, and examples to ensure all team members understand how to apply the design system effectively, minimizing design debt and maintaining a high-quality user experience.
How Power UI Simplifies Design in Power BI
