“We want to write as little software as possible, and we want it to have as much value as possible. If you actually focus on that, it means you have to be close to your customer." Dave Thomas is the founder & chairman of Bedarra Corp, creator of IBM Smalltalk, VisualAge for Java, Eclipse, Kx Analyst workbench and Skills Matter YOW! Australia conferences. In this episode, Dave shared about his personal research, 42D, on ideas we can use to develop high-value software rapidly. He started by describing the current developer’s productivity challenges and touched on the idea that big is not better, relating to the size of the team and code base, and how development tools are becoming more complicated and complex. We then discussed the importance of developers understanding domain knowledge, leveraging tools such as decision tables and spreadsheets, and how the choice of programming language actually matters. Towards the end, Dave shared about using a data-centric approach to deal with legacy systems and his perspective on query as the future of programming.

“Testing is an activity that happens throughout. It is not a phase that happens at the end. Start thinking about the risks at the very beginning, and how we are going to mitigate those with testing." Janet Gregory and Lisa Crispin are the co-authors of several books on Agile Testing and the co-founders of Agile Testing Fellowship. In this episode, Janet and Lisa shared the agile testing concept and mindset with an emphasis on the whole team approach, which was then followed by an explanation of the holistic testing concept with a complete walkthrough how we can use the approach in our product development cycle, including how Continuous Delivery fits into holistic testing. Janet and Lisa also described some important concepts in agile testing, such as the agile testing quadrants (to help classify our tests) and the power of three (aka the Three Amigos).

“We need to consider our system that we built as sociotechnical systems. The system is more than the sum of its parts. It’s a product of their interactions. We need to focus on improving the performance of the whole, instead of separate parts of the system." Susanne Kaiser is the author of the upcoming book “Adaptive Systems with Domain-Driven Design, Wardley Mapping, and Team Topologies: Architecture for Flow”. In this episode, Susanne explained how she connected the dots between 3 different methodologies–Wardley Mapping, Domain-Driven Design, and Team Topologies–to design and build adaptive systems for a fast flow of change and why it is important for any organization to have adaptive systems. Susanne went in depth to explain about the Wardley Mapping strategic framework, its five sections, and how they support designing and evolving effective business strategies based on situational awareness and movement following a strategy cycle. She then explained how to translate from a Wardley map into Domain-Driven Design, how DDD helps in applying the Wardley Mapping doctrine principles, before then explaining how Team Topologies helps to create effective team boundaries and optimize team’s cognitive load. Towards the end, Susanne shared from her experience how we can apply this process in our organizations, as well as in legacy systems.
