About

Grain is a publication by Arkhean on the practice of engineering review. The writing here is about the decisions engineers make under uncertainty — how those decisions are documented, examined, and traced back to evidence.

The name comes from material science. The grain of a metal determines where it holds and where it breaks. Reading the grain is what engineers do before they apply load. This publication tries to do the same for engineering processes: to find the underlying structure before the pressure arrives.

What this covers

The articles here are about things that are usually left vague in engineering practice: the difference between a risk and an assumption, what a design review is actually supposed to produce, and how to write a validation plan that is traceable rather than decorative.

The recurring topics are:

• Engineering risk reviews — what they should produce and why most do not
• Validation planning and gap analysis — closing the distance between assumption and evidence
• Design assurance — the discipline of demonstrating, not just asserting, that a design meets its requirements
• Assumptions, issues, and open questions — how to track what you do not yet know

The format

Articles are long enough to be useful and short enough to be read in one sitting. They start from practice, not from theory. Each one is an attempt to make something specific clear that is usually left to inference.

There are no comments, no newsletter, and no subscription to manage. If an article is worth returning to, bookmark it. If it is useful to someone else, pass it on directly.
