📋 Wenn der Code zur Single Source of Truth wird, stimmt meistens etwas nicht. Java Champion @martinelli.ch zeigt auf der #BaselOne26, wie #SpecDrivenDevelopment Spezifikationen wieder zur Grundlage der Entwicklung macht. 🎙️ Zum #BaselOne Programm: baselone.org#programm #Java #AI

Most modernization projects do not fail because of technology. They fail because nobody knows anymore what the old system actually does. In my new blog post, I show how the Brownfield Workflow of the AI Unified Process (AIUP) solves this: martinelli.ch/modernizing-...

This video talks about Spec-Driven Development: write the spec first, then let the agent build. The spec stays the source of truth, and the code follows. That is also the idea behind the AI Unified Process (AIUP). Requirements first. Traceable. Reviewable. Have a look: youtu.be/odbNXv9xXjc
Simon Martinelli - Lessons from Spec-driven Development - AI Native DevCon June 2026
In many projects, specifications and code drift apart over time. Requirements change, documentation becomes outdated, and developers rely mainly on the code. This increases risk and makes changes…

Why System Use Cases Are Perfect in the Age of AI - Martinelli
AI is changing how we build software. Code, tests, and even UI can be generated very fast. This is powerful, but it also exposes a big weakness in many projects. AI does not understand intent by…

Stop reducing the SDLC to just programming. It is a process that spans everything from the initial idea to the application in a production environment. Programming is merely a means to an end. Unfortunately, none of the tool vendors seem to understand this.

…Interessiert sich der US-Präsident doch nicht für Fussball? 🤨 Der Orange interessiert sich nur für sich, alles andere ist nur «geheuchelt», wenn es ihm zu Pass kommt. 🍊 www.srf.ch/news/interna...
The Trump administration inked a $1.6 billion deal for a U.S. company to mine tungsten in Kazakhstan. The company is linked to Trump’s sons & Commerce Secretary Howard Lutnick’s sons, who will be personally enriched by their fathers’ policy decisions. The corruption is breathtaking.

AI can speed up development, but it doesn't replace software engineering. In this webinar, Simon Martinelli shares why devs still need to guide AI to build production-ready apps. 🔗 Watch the full webinar: www.youtube.com/watch?v=IFds...
Simplicity is a great virtue but it requires hard work to achieve it and education to appreciate it. And to make matters worse: complexity sells better. - Edgar Dijkstra #quotes #quoteoftheday
Elon Musk spent $290 million getting Trump elected. During this midterm cycle, he's spent $85 million. In total, that’s 0.0375% of his $1 trillion net worth. Oligarchs can rig the system at the expense of everyone else, and only spend pennies doing so. We must get Big Money out of politics.
🧩 Was wäre, wenn nicht mehr der Code die Quelle der Wahrheit wäre? In „Spec-driven Development mit KI“ zeigt @martinelli.ch auf der W-JAX, wie Anforderungen, Diagramme, Modelle, Code & Tests mit KI verbunden werden. 🔗 https://f.mtr.cool/iyvbziutuw #jaxcon #EnterpriseAI
Another implication of Conway's Law is that if we have managers deciding on teams, and deciding which services will be built, by which teams, we implicitly have managers deciding on the system architecture. - Ruth Malan on Conway's Law #quotes #quoteoftheday
Sehr Vieles das aus der SaaS-Produktentwicklung, meistens aus den US, stammt, passt nicht in den Enterprise-Kontext.
