Ken Power is challenged with the heuristic “Use a systematic mechanism of learning” from the Simon Wardley Doctrine repository (https://wardleypedia.org/mediawiki/index.php/Doctrine_Patterns#Use_a_systematic_mechanism_of_learning). He shares how he learns, with structure and unstructured approaches, and also how teams and organisations can learn. Our discussion goes into complex adaptive systems, different patterns, and how learning is one of the qualities present in resilient organisations. Last but not least how complexity and mapping can go hand-in-hand. Ken recommends the following resources: Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime from Sean Carroll The Subtle Art of Not Giving a F*ck: A Counterintuitive Approach to Living a Good Life from Mark Manson 7 Rules for Positive, Productive Change: Micro Shifts, Macro Results from Esther Derby The Heat of the Moment: Life and Death Decision-Making From a Firefighter from Sabrina Cohen-Hatton Lex Fridman Podcast (https://lexfridman.com/podcast/) Rasa Chat‪s Ken (@ken_power) is an engineering leader with more than 20 years’ experience in software engineering.

 A new episode is out, and today we feature Dawn Ahukanna (@dawnahukanna). She is challenged with the heuristic “Your solution should not be more complicated than the problem” from the Xebia Essentials repository (https://essentials.xebia.com/kiss/). We discuss what solution vs problem space needs, and how different disciplines complement each other in order to deliver value. Dawn shares with us what are the heuristics that allow people with different perspectives to cross their paths to solve a complex problem. Dawn recommends the following resources: As-is scenario mapping (https://www.ibm.com/design/thinking/page/toolkit/activity/as-is-scenario-map) To-be scenario mapping (https://www.ibm.com/design/thinking/page/toolkit/activity/to-be-scenario-map)  Service Blueprint (Sequence diagram for people and interactions) (https://www.nngroup.com/articles/service-blueprints-definition/) Cynefin framework (https://en.wikipedia.org/wiki/Cynefin_framework) Wardley maps (https://medium.com/wardleymaps) Dawn Ahukanna (@dawnahukanna) is a Design Principal at IBM Design. She's always been curious about how "things" work, taking things apart and trying, failing, learning, trying again, failing, trying again and finally putting them back to together. Sometimes, making completely new things in the what should have been a re-assembly process. She started her career as a Chemical Engineer, taking things apart at the atomic level and figuring out how they worked. Then simulating and emulating abstract models by developing and programming software. Finally progressing to figuring out how people work, without taking them apart or simulating, as a Design Principal and Front-End Architect. Her mission: To design, develop and deliver digital user experiences that hopefully delight, definitely enables or at least don't frustrate, the clients and users.  

This week, Steve Pereira will be challenged with the heuristic “Remove bias and duplication” from the Wardley Doctrine repository (https://wardleypedia.org/mediawiki/index.php/Doctrine_Patterns#Remove_bias_and_duplication). We will discuss different contexts where duplication can hinder or accelerate, and the importance of value streams. He shares his experiences about using weak signals to detect friction within organisations, helping them to reorganise to enable the flow. Steve recommends the following resources: Value Stream Mapping: How to Visualize Work and Align Leadership for Organizational Transformation by Karen Martin and Mike Osterling Value Stream resources at https://visible.is/#thinking  Mastering Software Delivery with Value Stream Management from Jeff Keyes Steve (@SteveElsewhere) is a DevOps enthusiast and an expert in software team performance with more than 20 years of experience.

In this episode, our guest Trond Hjorteland is challenged with the heuristic “Complex systems evolve out of simple systems that worked” from Embedded Artistry repository (https://embeddedartistry.com/blog/2018/04/26/embedded-rules-of-thumb/). We discussed how communication is important, and moving from the big picture to code and back. He shares the techniques and practices to have crucial discussions with people with different perspectives involved in the creation of software. Trond recommends the following resources: Anything from Umberto Eco (https://en.wikipedia.org/wiki/Umberto_Eco) Thinking in Systems: A Primer by Donella H.

“Design for constant evolution” is the heuristic for our guest, Edzo Botjes. The heuristic is part of the Simon Wardley Doctrine repository (https://wardleypedia.org/mediawiki/index.php/Doctrine_Patterns#Design_for_constant_evolution). Edzo discusses resilient and antifragile systems as part of his research. We discuss how organisations are addressing these topics, and what are the current market needs, given that it is a complex topic. Edzo suggests: Foundations of Enterprise Governance and Enterprise Engineering from Jan A.P. Hoogervorst Rethinking the Fifth Discipline from Robert Louis Flood Edzo Botjes (@edzob) is an Enterprise Engineer with more than 15+ years’ experience. He believes that Enterprise Engineering covers Enterprise Architecture and the skills needed to implement innovation, governance, and architecture realistically. This implies that Group Psychology, IT Security Architecture, Technology Innovation, and Ethics are a few topics that should be included in the developing strategy and architecture.  In 2020 Edzo wrote his Master titled "Defining Antifragility and the application on Organisation Design” and graduated with the highest distinction. Edzo is currently working on the new version of DYA, a view on Enterprise Architecture. Edzo is since this year part of Xebia Security with specialisation on the resilient organisation.

New year, new episode. Mykola Gurov is the first guest of the year, and we challenge him with the heuristic “Diagnose before cure” from the Xebia Essentials repository (https://essentials.xebia.com/diagnose-before-cure/). Mykola shares his opinion about observability and the importance to challenge our assumptions and bias. Focus on the purpose of the software rather than the technical details. We discuss testing in production, the different techniques to be effective, reduce the feedback cycle, and do it safely. We end up talking about the differences between traditional approaches to testing software versus modern ones. Mykola recommends: Unit testing is overrated blog post by Alexey Gulob (https://tyrrrz.me/blog/unit-testing-is-overrated) Testing of Microservices blog post by André Schaffer (https://engineering.atspotify.com/2018/01/11/testing-of-microservices/) Mykola (@ngurov) is a software engineer. Working at bol.com since 2015. Mostly within “feature delivery” teams (logistics, supply chain) with occasional detours towards platform development. He is a proponent and adopter of rapid feedback techniques in software development: thorough functional testing in development; progressive feature delivery and trunk-based development; testing on production (shadow and live). On the technical side, he is a believer in micro-services; preference for higher-tier testing instead of heavy use of mocks.    

Today Laveena Ramchandani will share her experiences about the heuristic “Tests should be fast, reliable and independent” from the Xebia Essentials repository (https://essentials.xebia.com/independent-tests/). We discuss how to combine these 3 qualities to the test practices.

She will share her experiences and opinion about the heuristic “Distribute power and decision making” from the Simon Wardley Doctrine (https://wardleypedia.org/mediawiki/index.php/Doctrine_Patterns#Distribute_power_and_decision_making). She will share her heuristics to move between different leadership styles, such as Command and Control and Misson Command. We discuss the merits of the different styles, as well as how a manager can sense and discuss it with the people and the teams. We end up with the differences between an enterprise and a scale-up, and the trade-offs for a manager.  Melissa recommends: State of DevOps report - https://cloud.google.com/devops  Accelerate book from Nicole Forsgren, Jez Humble and Gene Kim Melissa Benua (@queenofcode) has worked in nearly every software development role—dev, test, DevOps, and program management—at companies big and small and somewhere in-between.
