À propos de ce contenu audio

We’ve consistently observed a common pattern: regardless of the architectural approach—from traditional enterprise to more hands-on, emergent methods—teams face similar obstacles when building effective systems. The core challenge remains how to build software that truly works and enables a smooth flow of delivery. To address this, we’ve started a new series, Stories on Facilitating Software Design and Architecture. In these sessions, we focus on real-world experiences from our community, sharing practical stories about the alternative approaches that have delivered results. It’s about moving beyond the theoretical and into the practical, shared wisdom of what actually works.Copyright Virtual Domain-Driven Design Economie Management Management et direction Science Sciences sociales

  • Everyone Had an Opinion But Nobody Changed Their Mind
    May 12 2026

    We've all been in that meeting. Someone proposes a solution, someone else proposes a different one, and within minutes the room has split into camps. People stop listening and start waiting for their turn to argue. Whatever decision comes out feels less like a conclusion and more like whoever had the most stamina won.

    Laïla Bougria has spent over two decades in software engineering, much of it working in messaging and event-driven systems at Particular Software. Her story isn't a single incident — it's a pattern she's seen repeat across teams, companies, and years: smart people in a room, a decision to make, and a conversation that quickly becomes "my opinion versus yours." At Particular, Laïla learned to break this cycle through an RFC process that forces a different question before solutions are even compared: what problem are we solving, and for whom? That reframing removes a surprising amount of conflict before it starts. But what happens when two teams share a decision and neither is technically wrong? Or when you're convinced something is a mistake, and the team moves on without you?

    This conversation digs into the emotional weight of architectural decisions — the gut reactions we dress up as rational analysis, the perfectionism that makes letting go feel like losing, and the personal practices that help you stay honest with yourself over time. Laïla shares how she builds evidence instead of winning arguments, why she runs personal retrospectives every six to twelve weeks, and what it taught her when she gathered evidence against a decision and found… nothing.

    Key Discussion Points

    • [00:01] The Pattern That Keeps Repeating: Smart people in a room, comparing solutions before they've agreed on the problem — and why it turns personal fast
    • [00:04] Problem Before Solutions: How Particular Software's RFC process reframes decisions by requiring a shared problem statement before alternatives are discussed
    • [00:06] "That's a Horrible Idea": Turning gut reactions into constructive questions about hidden assumptions and risks
    • [00:09] When Two Teams Share a Decision: Navigating the give-and-take of event granularity between teams, and using coupling arguments that land because they serve both sides
    • [00:14] Boundaries as Everyone's Job: Why service boundaries shouldn't be a few people's problem and how curiosity about the business domain surfaces issues early
    • [00:18] Building Evidence, Not Arguments: The story of tracking bugs to prove a hunch right — and the equally important story of tracking evidence and finding none
    • [00:25] Personal Retrospectives: A quarterly practice for resolving frustration, testing your instincts against reality, and genuinely letting go

  • Why Drawing the Same System Reveals Different Architectures
    Apr 28 2026

    We often assume that architects working on the same system share the same understanding of its structure. They're looking at the same code, attending the same meetings — surely they see the same thing. But what happens when you actually test that assumption?

    That's the challenge Aino Corry faced when she was brought into a large American company to help a team of architects understand their monolith before breaking it into microservices. When she asked for a full day, the response was skeptical: "A whole day? We're just gonna look at some diagrams." But Aino held firm. Drawing on work with Simon Brown, she gave the architects a deceptively simple task: draw the component diagram of the monolith from memory, without looking at the code. Then they put every diagram on the wall — and walked the line. The surprise was immediate. Architects who'd been working on the same system for years had fundamentally incompatible mental models of its core structure. Using the liberating structure 1-2-4-All, Aino turned that surprise into a conversation unlike any they'd had before — one where not knowing became acceptable, and the quiet voices finally had room to speak.

    This conversation explores how externalising individual mental models creates richer architectural discussions, why structured facilitation changes who gets heard, how to handle the vocal skeptic who thinks you've wasted their day, and the consultant's dilemma of never quite knowing if your workshop made a lasting difference — unless you happen to have a spy in the organisation you drink red wine with.

    Key Discussion Points

    • [00:01] Setting the Stage: Aino explains how she came to facilitate architecture workshops even though she's no longer a practicing architect — and why the same facilitation dynamics apply regardless of domain
    • [00:02] A Whole Day? Really?: The team's resistance to spending a full day on understanding before doing, and why Aino insisted on it
    • [00:04] Draw What You Know: The deceptively simple exercise of drawing the monolith's component diagram from memory — without looking at the code
    • [00:05] Walking the Wall: The moment architects discovered their mental models of the same system were fundamentally incompatible
    • [00:08] You Can't Win Them All: How one vocal skeptic dismissed the day as a waste of time, while newer team members found it invaluable
    • [00:12] The Champion Skeptic: Aino reflects on what she'd do differently now — using Linda Rising's pattern to redirect skepticism into constructive energy
    • [00:16] The Consultant's Dilemma: How do you know if your workshop actually made a difference once you've left the building?
    • [00:22] To Understand Everything Is to Forgive Everything: Why seeing each other's mental models changed judgment into curiosity

  • When Method Wars Hide the Real Problem
    Apr 14 2026

    We fight about Agile versus Six Sigma, build versus buy, in-house versus outsourced. We pick our camps and defend them with the certainty of people who've never mapped the territory they're fighting over. But what if the real problem isn't which method is right — it's that we're choosing methods before we understand what we're building?

    That's the story Simon Wardley brought to this conversation, centred on HS2 — Britain's high-speed rail project. CIO James Finley needed to build a virtual railway before the physical one, because it's cheaper to mess up a virtual landscape than the English countryside. The typical government approach would bundle everything into domain-based contracts and outsource. Instead, James spent a Sunday afternoon doing something different: he mapped the entire system. Not a component diagram. A proper map — with users at the top, a chain of needs underneath, and a critical question about each component: how evolved is it? Custom-built land referencing systems on the left. Commodity compute on the right. Suddenly, the methodology war dissolved. You need Agile where things are novel and changing. Six Sigma where things are commodity. Lean in the middle. They built the system using multiple methods simultaneously — ahead of schedule, under budget.

    But Simon doesn't stop at the success story. The conversation digs into the harder questions: what happens when people have built 20-year careers on a single methodology and you're implicitly telling them they've been doing it wrong? How do you handle dominant voices who weaponise information asymmetry in collaborative mapping sessions? And why do maps create safer spaces for challenge than stories — even when the topic is as divisive as Brexit?

    Key Discussion Points

    • [00:01] The Virtual Railway: Why HS2 needed to model the entire railway digitally before breaking ground — and how James Finley approached it differently from typical government IT
    • [00:06] The Sunday Afternoon Map: How plotting components on an evolution axis — from genesis to commodity — dissolved the methodology debate
    • [00:10] Burning the Heretic: What happens when Simon tells Agile conferences that Agile isn't appropriate everywhere — and gets the same reaction at Six Sigma conferences
    • [00:13] The Excuse Loop: Why "we didn't specify the requirements well enough" is the most dangerous sentence in software delivery
    • [00:16] The Military Advantage: How situational awareness training gives people like James an instinct for context that methodology-trained professionals often lack
    • [00:21] Practicing on Real Terrain: Andrea's experience joining a transport research group to deliberately practice mapping on systems, not just theory
    • [00:26] Defeating Weaponised Silence: Using multiple mapping groups to dilute political power — you can hide the Eiffel Tower in your map, but it appears in six others
    • [00:31] Maps Over Stories: Why challenging a map feels safe but challenging a story feels like challenging someone's leadership — and how Brexit supporters and opponents could argue productively through a map
