Language Bank: Pushing Back on Unrealistic Deadlines

As an Assistant Plant Manager, you’ll often need to manage expectations, so having a script for pushing back on unrealistic deadlines is crucial. Here are some phrases you can use:

Use this when a deadline is impossible to meet without compromising quality or safety.

“I understand the urgency, but meeting this deadline would require us to cut corners on [critical process], which could lead to [negative consequence]. I propose we adjust the timeline by [number] days to ensure we maintain our quality standards.”

Metrics That Matter

Tracking the right metrics is essential for monitoring plant performance and identifying areas for improvement. Here are some key KPIs to monitor:

• Production output: The total quantity of products produced within a given period.
