## The Problem
Media fills (aseptic process simulations) must "stress" the process to be valid. If your protocol doesn't include a representative range of planned and unplanned interventions, the FDA may consider your simulation inadequate to prove sterility assurance.

**Example:** You're designing a media fill protocol. Do you know which specific interventions (like shift changes or minor adjustments) *must* be included to satisfy FDA expectations?

Here's how KeyPedia helps you design robust media fills: Just ask KeyPedia to list the required intervention types based on current regulatory standards


**Why?** Because KeyPedia's input is fed from guidance documents, FDA regulations, good practices, FDA-483s, and Warning Letters.

## 1. Ask
Ask KeyPedia: 
> I want to run a media fill on a conventional aseptic filling line. Tell me the type of planned and unplanned interventions I should include in my protocol.

## 2. Review
KeyPedia lists critical interventions, differentiating between Routine/Planned (e.g., aseptic assembly, shift changes) and Unplanned/Corrective. **See the complete KeyPedia response in Dan's LinkedIn post below.**

## 3. Implement
Incorporate these specific interventions into your media fill protocol to ensure it withstands regulatory scrutiny.
