Season Four Wrap: Whose Design Is It Anyway? with Swadia, Windholtz, Rezentes, and Keathley
To close off this season and conclude our deep dive into system and application architecture, today’s episode is a special panel discussion on a topic that has provoked a mix of answers that range from the controversial to the philosophical — “What does domain-driven design mean to you?” For the final word on this subject, we welcome back software developers Chris Keathley, Japa Swadia, Mark Windholtz, and Miki Rezentes. Our first hot take comes from Miki, who shares her thoughts about how domain-driven design developed because the tech industry undervalues communication. Following this, Mark and Japa discuss how domain-driven design gives developers a context for what they create while informing how you code using Elixir. We then touch on whether domain-driven design makes it easier or more difficult to change your code and how communication is valued within a business context. We explore key domain-driven design concepts, including the role of bounded contexts, and how this design ethos can help you appeal to stakeholders such as product managers. After Miki highlights the reasons why communication should be seen as a vital tech skill, each guest provides their final thoughts on domain-driven design. Tune in for this season’s insightful finale and find out which of today’s guests is the winner of “Whose Design Is It Anyway?”
