What is the primary purpose of field observations in a failure investigation?

• A. To assign blame
• B. To support conclusions with observed data
• C. To promote a product
• D. To replace manufacturer data

Answer: (B)

Field observations provide direct, objective evidence about how the system performed in its actual service conditions. By examining the site, you gather real-world details such as material condition, installation practices, signs of moisture or water intrusion, fastener patterns, flashing integrity, and observed damage. This on-site data lets you test ideas about why the failure happened and piece together a plausible sequence of events based on what actually occurred, rather than guesses. The aim is to support conclusions with observed data, giving the investigation a solid, evidence-based foundation. This approach is not about assigning blame or marketing a product, and it does not replace manufacturer data. Field observations complement manufacturer information by showing how the system behaved in the field and under real conditions, which helps verify or challenge design assumptions and identify factors the lab or manufacturer data alone might not reveal.
