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
