Executive summary

The site looks premium and mostly works. One calculator defect and two engineering-accuracy errors should be fixed before launch. The rest are polish items.

I tested every interactive function on 7 device/browser combinations, ran automated checks (Lighthouse, axe, W3C validator), and reviewed the technical copy against the codes and standards a process engineer would expect.

Method · 3-day plan

How the reviewis run.

  1. Day 1

    Functional & cross-device

    Every link, form, calculator and interactive element, tested on Windows, macOS, iOS and Android in Chrome, Safari, Edge and Firefox. Console errors and broken links logged.

  2. Day 2

    Accessibility, UX & performance

    WCAG 2.2 AA checks (axe plus manual NVDA/VoiceOver), Core Web Vitals on throttled mobile, and a heuristic UX walk-through as a plant engineer and as a procurement lead.

  3. Day 3

    Technical content & report

    Units, nomenclature, codes and standards cross-check. Each finding is screenshotted, given a severity and reported here with fixes, quick wins first.
