Modern products are rarely single, fixed configurations. Instead, they exist as families of variants designed to meet different customer needs, regulatory requirements, and operational environments. Managing this complexity requires a disciplined approach to product structure, configuration management, and verification. One of the most important concepts supporting this effort is the 150% eBOM.  That leads to […]

Why Test Failures Occur in Software Testing In software development and system engineering, test failures are often interpreted as evidence that the product contains defects. However, experienced engineers know that test failures can originate from multiple sources across the development lifecycle, not just the code itself.  This post originated from a read of a LinkedIn […]

Why SDVs Demand Stronger Verification and Validation The shift to software‑defined vehicles (SDVs) is transforming automotive engineering—and multiplying its risks. As ECUs consolidate into centralized compute platforms and features increasingly rely on AI, machine learning, and over‑the‑air (OTA) updates, safety, cybersecurity, and reliability take center stage. This complexity makes verification and validation (V&V) more critical than ever. Regulators are tightening expectations […]

We are well advised to think in terms of principles. Everything is context-dependent, the degree of diligence commensurate with the associated risk.  We […]
