The Hidden Cost of Poor Traceability — and How to Fix It Across the Lifecycle

The Hidden Cost of Poor Traceability — and How to Fix It Across the Lifecycle Every engineering team believes they “have traceability.”Few actually do. In most organizations, traceability exists only in fragments — requirements in one tool, test results in another, defects somewhere else, architecture in a modeling tool, and changes scattered across spreadsheets and Git systems. Everything is connected […]

The Hidden Value of Traceability in Embedded DevOps

Why linking requirements, commits, and tests is more than paperwork. The truth about traceability Ask most embedded engineers what they think about traceability, and you’ll probably get a groan. It’s usually associated with audits, checklists, or hours of documentation that pull you away from actual engineering. But in reality, traceability is not about bureaucracy — it’s about […]

From CI/CD to MBSE: Automating the Model-Based Lifecycle

How Model-Based Engineering (Rhapsody, Cameo, Capella) can plug into CI/CD Traditional document-centric engineering no longer cuts it. The shift to Model-Based Systems Engineering (MBSE) offers a structured, model-driven way to capture requirements, architecture, behaviour, and verification in a unified environment. Model-Based Systems Engineering (Wikipedia) At the same time, software and firmware teams either are looking into or […]

Requirements: Lions and Tigers and Bears, Oh My!

Why Spreadsheets, Word Docs, and Lightweight Tools Fall Short for Safety-Critical Engineering When Dorothy and her companions wandered through the forest in The Wizard of Oz, they feared the unknown dangers lurking behind every tree: “Lions and tigers and bears, oh my!” In the world of safety- and mission-critical projects — aerospace, automotive, medical devices, defense — the dangers aren’t […]
