Utrecht, The Netherlands

Creating insights from data and designing dashboards using Power BI is my passion. Originally from Germany, I moved to the Netherlands to study Cognitive Psychology (MSc. Psychology). During my studies, I realized that I am not only interested in human behavior but also the numbers & statistics trying to explain it.

I combine my knowledge about the mind with my passion for data (visualization), process improvement, and innovation.

Power BI Design: Thinking Outside the Box


Designing a Power BI dashboard can be challenging. While Power BI is a powerful tool for data visualization, many people are hesitant to move away from traditional report design. This session will show you how to think outside the box and create dashboards that grab your audience's attention.

Topics covered:

- The challenges of designing Power BI dashboards
- Different design options for Power BI dashboards, such as infographics, dark mode, minimalism, and interactivity
- How to choose the right design for your audience
- Effective color choices for Power BI dashboards
- Design best practices

Who is this session for?

This session is for anyone who wants to learn how to create more visually appealing and impactful Power BI reports. You do not need massive Power BI experience to follow along.

By the end of this session, you will be able to:

- Understand the benefits of using a different design for your Power BI reports
- Chose the right design for your audience
- Understand the basics of design principles and how to use them in Power BI
- Sell your ideas to the business and get approval for your designs

From data to action: Driving decision-making with Power BI

Let's face it; there are probably not many people designing dashboards and reports just to have something pretty to look at. Companies asking for dashboards want to get insights and eventually take action with these insights.
Many Power BI dashboards companies use do not fully fulfill this need. Often there is data, which is good, but taking action and taking the next step with the insights needs many additional steps... When we take a step back, the dashboards were intended to lessen the workload and not add to the workload.

In this session, "From Data to Action," I will show how you can visualize the data in a way that helps companies to take the next step. Often, this is not complicated, and you don't need to buy additional tools. Just some visual tweaks will go a long way!

Also, this session will focus on asking the right questions and tailoring the design to your audience. So it's a mix of visuals, examples, and theory about choosing the right design to answer the (actual) question.

Whether you are a business analyst, a data enthusiast, or a decision maker, this session will help you to bring your dashboards to the next level. It will also help you to communicate more clearly to the team what you are looking for, even if you don't know everything about Power BI and dashboard design.

Paint it Black: Rocking Dark Mode Dashboards

Designing Power BI reports can be tough; designing them in a different way than the old-school white background and standard Power BI color scheme can be even harder. Most people are afraid to use something other than the standard provided; however, designing a dashboard in a dark mode style (black or dark color background) is not only aesthetically better (okay, personal opinion 😉) but also can enhance user experience. Just think about working with tools that all have dark mode all day and then suddenly opening a Power BI report brighter than the sun. Who wants that?

The session aims to guide the audience through the process of designing a Power BI report that is presented in dark mode. From selecting appropriate visual elements to optimizing readability and accessibility, guidelines will be presented to create stunning visualizations that leave a lasting impression. And, of course, there is also some advice on how to sell this to the business!

Key topics
- Understand why a dark design can actually be beneficial
- Learn about the art of contrast and effective color choices
- Tips to increase readability and ease for the eyes
- Best practices in general when designing in Power BI
- How to sell this to the business

Visualizing Data for Non-Data Experts: Making Reports Accessible to All

Creating reports that effectively communicate data insights to non-data experts can be tough! While you as a developer know all ins and outs of Power BI and the data in the report, your audience maybe just got started or are less familiar with interpreting data.

The charts, graphs and tables you provide with the intention to inform, engage and trigger the audience may even have a complete different effect: they confuse and overwhelm your audience.

In this session, we'll explore how to visualize data in a way that is accessible to everyone, regardless of their level of expertise. The sessions attendees will learn how to identify their audience's needs, select the appropriate visualizations for their data, and present their findings in a clear and concise manner.
The session starts with discussing the importance of storytelling and how it can be used to create engaging reports that resonate with the target audience. Then it covers the key principles of effective data visualization, including:

* Choosing the right chart or graph for the data
* Simplifying complex data to make it easily digestible
* Incorporating visual cues to highlight important information
* Designing for accessibility, including colorblindness and other disabilities

Throughout the session, I provide practical examples and demonstrations of how to create effective data visualizations using Power BI.

The audience of the session will leave the session with a solid understanding of how to create reports that are accessible, engaging, and informative for everyone in their organization.

Storytelling & Power BI - Creating Power BI reports that connect with different audiences

Designing a report that will be viewed and used by different audiences can be challenging. You want to present information in an actionable, informative, and visually appealing way. However, users across an organization may have various requirements and Power BI experience levels. While some users need detailed information presented in different dimensions with possibilities to filter and drill through, others may only look for key performance indicators. Some users like to click through a dashboard to see specific information, while others want to print it or have a quick look on the phone to see the most relevant information.
This session covers steps you can take to understand the needs of different audiences. Topics covered are:

- Techniques and questions you can ask to understand your audience and to gather the report requirements.
- Examples of different visualizations (and ways to format them) to communicate with different audiences and get your message across
- Providing a consistent look and feel (with templates and color schemes) to reduce the cognitive load when looking at a report
- Best practices & tips to design actionable, informative, and easy-to-understand reports.

By the end of the session, attendees will understand better how to create a Power BI report that connects with different audiences across an organization.

Dashboard Design - The icing on the cake

5 steps to put the icing on the dashboard(cake).
A session for beginning and intermediate dashboard designers showing some easy steps to make a dashboard visually appealing and easy to read.
The session's story is comparing building and designing a dashboard with baking a cake at a baking competition. Everyone has the same ingredients (data) and the same recipe (business question) but in the end, the cakes (dashboards) look different. Using the steps of this session you will learn how you can quickly improve a dashboard without spending too much time. The goal of the session is to inspire and guide dashboard builders and give them confidence in presenting their dashboard to the "jury" (the business) after building it.

Transform Your Power BI Reports with Storytelling Techniques

Are you struggling to make an impact with the Power BI reports you’ve created? Do you have a hard time targeting the report to the users viewing the report? If so, you're not alone. Many of us believe that creating a report is a straightforward task, but the truth is that designing an effective report requires careful consideration and a lot of practice.

In this session, I will explain, based on my personal experience and lessons learned through the years how you can improve the usability of your Power BI reports by incorporating storytelling elements.

First, we'll explore why storytelling is crucial to report design. You'll discover how it helps you connect with your audience, engage them, and ultimately supports them to take the right actions. We'll dig into techniques for identifying your audience's needs, what motivates them, and how to tailor your report to resonate with them.

Throughout the session, I'll share practical examples and insights gained from my own experiences. I'll showcase how I overcame common design mistakes, such as the "data dump" or the "cluttered canvas," to create actionable and effective reports. You'll also learn how to choose the right visuals, colors, and fonts to reinforce your narrative and create a cohesive, visually appealing report.

By the end of the session, you'll have a clear understanding of how storytelling can improve your Power BI reports, and you'll walk away with tips and tricks that you can immediately apply to your reports. Don't miss this opportunity to take your Power BI report design to the next level!
