Marijn is the guest of this episode, and he brings his heuristic: Do NOT rewrite from scratch if it is in production (https://marijn.huizendveld.com/design-heuristics/do-not-rewrite-from-scratch-if-it-is-in-production). He gives examples of how to evolve software in production, reducing the risk of building the same thing in a new tech stack. We discuss how the software evolution is connected to the business model of an company, and seems a technical design, can even impact the revenue model.

Our guest for this episode is Charity Majors. The pattern that serves as the stage for the episode is “Build Confidence” from the Object-Oriented Reengineering Patterns (http://scg.unibe.ch/download/oorp/OORP.pdf). Charity describes the infamous “death spiral”, where folks that produce code lack confidence in their processes and practices to deploy code to production. According to Charity, our job is not done until we close the feedback loop! Charity also gives excellent advice regarding patterns and heuristics: to understand a pattern or heuristic, take one that you see working, and modify it. Learn what comes out of that!

In this episode, we host Marco Heimeshoff. The interview starts with the heuristic “Optimise for future potential” from the DDD Heuristics repository (https://www.dddheuristics.com/design-heuristics/optimise-for-future-potential/). Marco will take us through the journey of optimising for future potential, where he explains the need for boundaries as an enabler to optimise different parts of a system. We explore the idea of discovering boundaries and how semantics plays a crucial role in the discovery process.

In this week's episode, we host Alayshia Knighten. She is challenged with the “Manage inertia” pattern from the Simon Wardley Cotrine repository (https://wardleypedia.org/mediawiki/index.php/Doctrine_Patterns#Manage_inertia). She shares how she manages expectations to manage inertia with their customers. For that time is needed! During our conversation, we discuss how we learn and what can we do to influence others to learn.

This week in the podcast, we feature Danyel Fisher. He brought the heuristic “Users are correct but not accurate” from his repository. As a starter, Danyel explains that users have goals that aren’t able to express well, and we need to use different methods to discover the needs. We discuss what makes a high performing team, and in his opinion, one of the distinctive factors is the usage of mixed methods for problem examination! And, he gave us a new heuristic to battle personal bias: “Delight and being wrong”! Danyel recommends: Signal: Understanding What Matters in a World of Noise by Stephen FewMaking Data Visual: A Practical Guide to Using Visualization for Insight by Danyel Fisher and Miriah Meyer Danyel Fisher (@FisherDanyel) is a User Data Expert for Honeycomb.io.

Episode 58 is out. A long journey, and today with us, we have Phillip Carter. Phillip brings a heuristic from his repository: “Focusing on developer experience can make your products more powerful and your teams more empowered”. We deep dive into what is developer experience and how some companies don’t get it right. For example, developer experience is different from the software development lifecycle. He also gives excellent advice on how to start developer experience initiatives within the company and leverage the economics of scale.

In this episode, we host Abby Bangser. She is challenged with the heuristic “Timebox the unknown” from the Xebia Essentials repository (https://essentials.xebia.com/timebox/). She shared a recent real-life example of how timeboxing can narrow the problem space towards a solution which can be helpful from day one. During our conversation, she shared some of her heuristics used daily.

Matt Lawrence is our guest, and he is challenged with the biggest heuristic so far: “Users spend most of their time on other sites. This means that users prefer your site to work the same way as all the other sites they already know.”, also known as “Jakob’s Law”. The heuristic is part of the “Jakob Nielsen Usability Heuristics” and can be found here: https://lawsofux.com/jakobs-law/.   Matt shares his experiences when it comes to usability, and what challenges you are faced when the system users are attached to a website. We discussed the different techniques that are valid to fulfil the user's needs when it comes to usability.   Matt recommends: UX Podcast - https://uxpodcast.com/UX Podcast Episode #235 - https://uxpodcast.com/235-internet-anxiety-david-swallow/Twitter as a source of knowledgeW3 Schools - https://www.w3schools.com/CSS Tricks - https://css-tricks.com/ Matt Lawrence (LinkedIn) is the co-founder of Digital Dynasty Design in Canada.

Mathias Verraes is the guest of this episode, and for the first time, we have more than one heuristic! Mathias brings three Loss Aversion heuristics from his personal repository. When we make decisions, we often do not explore options that have a risk of loss, even if that loss is balanced out by potential gains. These heuristics help you overcome that bias. We jump right into the rabbit hole, and Mathias brings the intersection of software engineering, psychology, and anthropology to exemplify the heuristics. During the interview, he shares techniques and practices that are part of his toolbox when working on software strategy and design.   Mathias recommends: Thinking, Fast and Slow by Daniel KahnemanThe Scout Mindset by Julia GalefYou Are Not So Smart - https://youarenotsosmart.com/The “It's Just Like...” Heuristic - https://verraes.net/2021/05/its-just-like-heuristic/Exaptation & managed serendipity - https://thecynefin.co/exaptation-managed-serendipity-part-i/Domain-Driven Design Europe conference - https://dddeurope.com/ Mathias Verraes (@mathiasverraes) is the founder and consultant at Aardling and organiser of the Domain-Driven Design Europe conference.

We are back with a new episode featuring Emily Bache. We start with a heuristic close to her work, “Working software is not enough, we need well-crafted software”. Emily shares her view on how code quality is essential, not only for the code maintainability but also to onboard new people on the team, increasing productivity. The interview flows towards team culture and management; she shares her experiences about how friction can arise in a team that produces software with no shared values and rituals that trickle down to code. She explains how all of those decisions and misalignments contribute to the complexity of the codebase. Emily recommends the following resources: Samman Technical Coaching - https://sammancoaching.org/Approval Tests - https://approvaltests.com/Text Test - https://www.texttest.org/Dig Deep Roots Newsletter - https://www.digdeeproots.com/articles/on/legacy/ Emily (@emilybache) is a Technical Agile Coach with ProAgile.

In this episode, Anand Safi is our guest. Anand is challenged with the “Most Valuable First” pattern from the Object-Oriented Reengineering Patterns repository (http://scg.unibe.ch/download/oorp/OORP.pdf). He starts to analyse value based on the different zoom levels: organisation, team and individuals. Anand explains the high degree of variance that the concept of value has. We end up discussing feedback cycles, psychology safety and OKR’s frameworks, and how all of it is connected. Anand suggests to follow: Marty CaganEsther DerbySimon Sinek Anand (@anandsafi) is an Engineering Leader for Mark43 - a public safety software company.

Jason Rosoff is the guest of this episode. We start the interview with the pattern “Personalized relationships for co-creation” from the Cloud Native Transformations repository (https://www.cnpatterns.org/organization-culture/personalized-relationships-for-co-creation). Jason explains the difference between a complex and complicated problem and how psychological safety plays an essential role in innovation. He shares some examples of how some companies constraint the physical environment of their offices to create space for people to talk and share their ideas. During the interview, Jason explains how relationships can play an essential role for information to travel across a network, how organisations can enable it, and how managers and executives can read weak signals latent in their organisations. Jason recommends the following resources: Radical Candor from Kim ScottMultipliers: How the Best Leaders Make Everyone Smarter from Liz Wiseman and Greg McKeown“You are not so smart” podcast (https://youarenotsosmart.com/podcast/)  Jason Rosoff (@jasonrr) has a passion for building products and teams that scale.

Today we host Johanna Rothman, and she is challenged with the heuristic “Get the team in a rhythm” from the Xebia Essentials repository (https://essentials.xebia.com/team-rhythm/). She starts explaining how the team rhythm and feedback cycles are connected and can strengthen each other. We discuss the role of a manager, and also how the managers should operate as a team, rather than be an extension of a team. Last but not the least, she shares her experiences with agile leadership, where it is necessary to move between discovery and delivery modes. And she left us with a heuristic, “Prune the decision tree”.

Monarch Wadia is our guest, and he is challenged with the heuristic “Master your tools” from the Xebia Essentials repository (https://essentials.xebia.com/master-your-tools/). Monarch gives a different perspective to master the tools, which stems from his experience as a Bootcamp organiser. We discuss the differences between colleague and Bootcamp education and how the education paradigm shifts, at least with our industry. It was the start to go down the rabbit hole on how technology influences our culture and how we, humans, are changing our interaction patterns. Monarch goes off script and recommends that we should decondition rather than discuss what we already know.  Monarch Wadia (@monarchwadia) proudly identifies as a self-taught developer. He sees software programming as a democratic industry that welcomes everyone who seeks to enter it with open arms, provided they're willing to put in the hard work needed to learn the ropes.
