Which of the following FME Workbench features is not commonly used in a production environment?

• A. Feature Caching
• B. The Inspector transformer
• C. The Logger transformer
• D. Visual Preview

Answer: (D)

In production you want tooling that runs automatically and efficiently without requiring an interactive UI. Visual Preview fits that design-time role: it visualizes features as the workspace executes, but it relies on the Workbench UI, uses extra CPU and memory, and doesn’t operate in headless servers or automated runs. Because production workflows are typically executed in FME Server/Engine without the UI, enabling previews would slow things down or be unavailable. So Visual Preview is not commonly used in production.

The other features support production needs: caching speeds up repeated reads, the Inspector helps diagnose issues during debugging or QA, and the Logger records operational events for monitoring and auditing. These align with a production workflow, whereas Visual Preview is primarily a development aid.
