“We have 10 different aspects of quality, and testing is just a subset of activities in the overall quality culture. You need to have a good testing practice, but it’s just a tiny part of quality culture." Janet Gregory and Selena Delesie are the co-authors of “Assessing Agile Quality Practices Using QPAM”. In this episode, we discuss how to elevate and improve our organization’s quality culture and practices. Janet and Selena begin by explaining what quality culture truly entails, distinguishing it from a narrow focus on testing. They describe the QPAM model, breaking down its 10 quality aspects and 4 dimensions to provide you with a comprehensive model for assessing your quality practices. Gain insights on why social and sociotechnical aspects of quality are more critical than technical ones, and explore some quality aspects such as feedback loops, development approach, and defect management. Janet and Selena also elaborate on why they consider defect management to be of the lowest priority and provide reasoning for their decision. Whether you’re a seasoned quality professional or a team leader striving for continuous improvement, this episode contains valuable takeaways to help you build a quality-driven culture that delivers high-quality results.

“If you can outsource it and if it’s not something that makes you different, you should use a service, because you’ll always be asked to do more things than you can build that are differentiated to your organization.” Are you ever frustrated by your software development team getting bogged down doing undifferentiated tasks, leaving less time for innovation? In this episode, Joseph Emison, co-founder and CTO of Branch Insurance and author of “Serverless as a Game Changer,” suggests how serverless technology can streamline the way we do software development. Joe starts by explaining the existing gap between the best and average software development teams, highlighting how teams often prioritize undifferentiated tasks instead of focusing on what truly sets them apart. He challenges the conventional wisdom that code is an asset and explains why it can be a liability. Joe breaks down the definition of serverless technology and delves into the real costs of software development. He addresses a few of the most commonly raised objections to adopting serverless: lock-in, security, and uptime. You’ll also learn the Branch development principle and how they successfully implement serverless architecture and gain many benefits from the approach.

“As software engineers, only a fraction of your time is spent coding. A lot of your time is spent thinking. And I’m not seeing LLMs taking that away from us anytime soon, at least, for now." Can AI help you learn to code? Will AI take your developer job? Join me discussing these topics with Leo Porter and Daniel Zingaro, the co-authors of “Learning AI-Assisted Python Programming”. In this episode, we discuss the impact of AI assistants on how we learn and approach programming, particularly for students and educators. We examine the shifting skillset of developers, emphasizing the importance of code reading, specification, testing, and problem decomposition over syntax and library semantics.
