Imagine a living copy of a jet engine that runs inside a computer at the same time as the real one — same wear, same temperatures, same stresses, updated second by second from sensors on the actual machine. That copy is a digital twin. A digital twin is a dynamic virtual model of a physical…
Every MBSE team is now asking the same question: do we move to SysML v2, and if so, when? It is a fair thing to wrestle with — SysML v1 has two decades of tooling, training and existing models behind it, while SysML v2 is a clean-sheet redesign. The short answer: v2 is more precise, more…
For twenty years, model-based systems engineering ran on SysML v1 — a language that was, honestly, a profile bolted onto UML: a software notation pressed into service for whole systems. It worked, but it creaked. SysML v2 is the ground-up rebuild — a systems modelling language with its own formal foundation, a first-class textual notation alongside the…
Configuration management, minus the jargon: what it is, the five core CM activities, who does the work, why it matters, and the real-world failures (Knight Capital, Mars Climate Orbiter, ERTMS) that prove the point.
A clear guide to the systems engineering V-model: how the V lifecycle links requirements and design to testing, verification and validation — plus how to read the V model diagram.
A look at the new system architecture canvas, the requirements drill-down, and the AI tools that have been quietly built around an INCOSE backbone. What the Visual Architecture Update Adds Capability What it means for you AI-native diagramming Describe the system and let reqi draft the architecture Connected to requirements Diagrams link to the requirements…
A systems engineering project does not fail because one clever person ran out of ideas. It fails in the gaps between people — the requirement nobody owned, the interface two teams each assumed the other was handling, the verification that fell between desks. The roles in systems engineering exist to close those gaps. Each one…
This article has moved. If you are not redirected, click here. Introduction: Building the Right Foundation It’s a familiar and frustrating narrative in the world of projects: budgets balloon, deadlines slide, and the final product, while technically sound, just doesn’t meet the users’ needs. Data suggests that up to 70% of IT projects fail to…
Before anyone designs a screen or writes a line of code, someone has to answer a deceptively simple question: what does the business actually need this project to achieve? A Business Requirements Specification (BRS) is the document that captures exactly that — the business goals, needs, and outcomes a project must deliver, in language the…
In 1999, NASA lost the $125 million Mars Climate Orbiter because two teams wrote the same requirement in two different units — pound-force on one side, newtons on the other. Nobody fumbled the math. The math was fine. The requirement was ambiguous, and an ambiguous requirement is a landmine with a long fuse: it sits quietly…
