Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a seasonal factor. Has there been any change in patient admissions or cafeteria foot traffic compared to previous months?

Why it matters: Understanding volume changes helps isolate whether the issue is related to demand fluctuations or internal processes. Expected answer: Patient admissions and foot traffic have remained consistent. Impact on approach: If consistent, we'll focus more on internal factors rather than external demand changes.

• Considering potential menu changes, have there been any significant alterations to the cafeteria offerings in the past month?

Why it matters: Menu changes could affect portion sizes, food preferences, or preparation methods, leading to increased waste. Expected answer: No major menu changes have been implemented recently. Impact on approach: If no changes, we'll investigate other operational aspects like inventory management or food preparation processes.

• Thinking about measurement accuracy, has there been any change in how food waste is measured or reported in the past month?

Why it matters: Ensures we're comparing apples to apples and not dealing with a data anomaly. Expected answer: No changes in measurement or reporting methods. Impact on approach: If consistent, we'll focus on actual waste increase rather than measurement discrepancies.

• Considering staff turnover, has there been any significant change in kitchen or cafeteria staff in the last month?

Why it matters: New staff might be less efficient or unfamiliar with portion sizes and preparation techniques. Expected answer: Normal staff turnover, no major changes. Impact on approach: If stable, we'll look more closely at processes and systems rather than human factors.
