“All data scientists and analysts should spend more time in the business, outside the data sets, just to see how the actual business works. Because then you have the context, and then you understand the columns you’re seeing in the data."

David Asboth, author of “Solve Any Data Analysis Problem” and co-host of the “Half Stack Data Science” podcast, shares practical tips for solving real-world data analysis challenges. He highlights the gap between academic training and industry demands, emphasizing the importance of understanding the business problem and maintaining a results-driven approach.

David offers practical insights on data dictionary, data modeling, data cleaning, data lake, and prediction analysis. We also explore AI’s impact on data analysis and the importance of critical thinking when leveraging AI solutions. Tune in to level up your skills and become an indispensable, results-driven data analyst.

“The quality is connected to the risk, and the risk is connected to the testing. If we don’t keep an eye on quality, our testing and development will drift, because we are no longer building the thing that people care about anymore."

Mark Winteringham is a quality engineer and the author of “Testing Web APIs”. In this episode, discover how holistic, risk-based testing strategies can transform your software quality. Mark explains how to prioritize our testing by understanding what users truly value and translating that into different risk-based testing strategies, such as testing API design, exploratory testing, automated testing, and acceptance test-driven design (ATDD). Mark also reveals the testing Venn diagram as our testing strategic roadmap. Finally, get a glimpse of Mark’s upcoming book “AI-Assisted Testing” and learn how AI will evolve the roles of testers and developers.

“Bureaucracy in itself is neither good nor bad. However, it often gets in the way and prevents important things you need to do. A good bureaucracy is lean, learning, and enabling."

Mark Schwartz is an Enterprise Strategist at AWS and the author of multiple books from IT Revolution. In this episode, we discuss his two latest books on the topics of bureaucracy and ethics. Mark begins by sharing his perspective on the impact of bureaucracy on digital transformation. He explains the definition of bureaucracy and why it tends to have a negative connotation. Mark describes the characteristics of a good bureaucracy and how leaders can play an important role in managing bureaucracy.

Next, Mark shares his reasons for writing about ethics in his latest book, why it is becoming more relevant in the digital world, and how leaders can make better ethical decisions in the current fast-paced business world.

“Soft skills are always going to be those ladders for you to climb in your career, whereas your tech skills can turn into snakes, meaning you’ve got to start again with another skill."

Jacqui Read, author of “Communication Patterns,” joins in this episode to discuss why strong communication skills are crucial for developers and technical leaders, often surpassing the importance of merely technical expertise. We delve into four key communication areas: visual communication, multimodal communication, communicating knowledge, and communicating remotely. During the discussion, Jacqui suggests several practical patterns you can immediately implement to level up your communication skills, such as knowing your audience, the big picture comes first, and perspective-driven documentation.
