Description
Factory & Site Acceptance Testing (FAT/SAT)
Overview
The OMI Verification Language Risk Guide — Desk & Field Edition (VLRG) is a two-page verification reference designed to help engineering teams reduce FAT/SAT review friction by improving precision in verification language.
Originally developed as part of the OMI Verification Readiness Framework (VRF), this guide consistently emerged as one of the most used and practically valuable artifacts during real-world acceptance programs. Teams relied on it during witnessed tests, document reviews, and customer discussions to avoid unintentional over-claims, scope expansion, and credibility erosion caused by imprecise language.
Based on that demand, OMI now offers the Desk & Field Edition as a standalone Verification Field Tool, available as a digital PDF and as laminated desktop reference sheets.
While developed in the context of Industrial Automation FAT/SAT, the language risks addressed—over-claiming, ambiguity, absolutist phrasing, assumption leakage, and authority drift—are common across acceptance activities in many engineered systems.
What This Tool Actually Is
The Verification Language Risk Guide is a structured reference that helps teams describe verification results accurately and defensibly by focusing on how evidence is communicated—not on what was tested.
It includes:
- A categorized table of high-risk phrases commonly used during FAT/SAT
- Clear explanations of why each phrase creates risk, independent of technical adequacy
- Identification of the type of risk introduced (e.g., over-claiming, ambiguity, authority drift)
- More precise alternative formulations aligned with what evidence actually shows
- Guidance on maintaining alignment between language, evidence, and configuration
- Practical examples relevant to witnessed tests, sign-off statements, and correspondence
This guide does not recommend test scope, define requirements, evaluate evidence, or imply acceptance authority. It addresses communication risk, not technical sufficiency.
How Teams Use It
The Desk & Field Edition is designed for real-time use, not narrative reading. Common use cases include:
- Desk-side or meeting-room reference during FAT and SAT discussions
- Reviewing test reports, presentations, and acceptance summaries before customer release
- Aligning language across multiple team members prior to customer-facing reviews
- Preventing unintended scope expansion during acceptance questioning
- Onboarding engineers new to acceptance-stage communication expectations
Because it is designed for real-time use, the guide is intentionally concise and formatted for rapid reference rather than narrative reading.
