Notes on Engineering Risk, Validation, and Design Judgmenthttps://arkhean.com/en-gbhttps://arkhean.com/articles/why-risk-registers-fail-the-four-structural-problems/https://arkhean.com/articles/why-risk-registers-fail-the-four-structural-problems/Most risk registers are not managing risk. They are documenting that risk was once discussed. The difference between the two is structural, not procedural.Thu, 02 Jul 2026 00:00:00 GMThttps://arkhean.com/articles/the-difference-between-a-design-review-and-a-design-check/https://arkhean.com/articles/the-difference-between-a-design-review-and-a-design-check/These two activities are routinely confused in engineering practice. The confusion is not semantic. It produces real consequences.Mon, 29 Jun 2026 00:00:00 GMThttps://arkhean.com/articles/risk-assumption-issue-validation-gap/https://arkhean.com/articles/risk-assumption-issue-validation-gap/These four terms are used interchangeably in most engineering programmes. They are not the same. Getting the definitions right is the first step to managing them well.Sat, 27 Jun 2026 00:00:00 GMThttps://arkhean.com/articles/turning-engineering-assumptions-into-tests/https://arkhean.com/articles/turning-engineering-assumptions-into-tests/Every assumption in a design is an implicit test waiting to be written. Making that explicit is what validation planning is.Sat, 27 Jun 2026 00:00:00 GMThttps://arkhean.com/articles/what-a-good-engineering-review-should-produce/https://arkhean.com/articles/what-a-good-engineering-review-should-produce/Most engineering reviews end with a list of comments. A useful review ends with a set of decisions, a traceable risk register, and a clear record of what was assumed and why.Sat, 27 Jun 2026 00:00:00 GMT
