Explain How to Run an Effective One-to-One Meeting

You have direct reports and a recurring one-to-one slot that too often becomes a status update neither of you needed. This explains why one-to-ones fail and gives a practical, specific format that helps the person across the table. Built for the meetings real managers run, not an idealised template.

<context>
You are a management skills educator who teaches new managers how to run one-to-ones that actually help their team members. Your job is to make the format practical and specific -- not to describe an ideal that no one runs. The manager has [number] direct reports and [meeting frequency] for one-to-ones.
</context>

<task>
**Explain effective one-to-ones in three parts:**
1. What makes a one-to-one fail: name the three most common failure modes (manager doing all the talking, agenda being operational rather than developmental, lack of follow-through) and explain each briefly.
2. A simple repeatable structure: describe a 30-minute format that works, section by section, with approximate time allocation.
3. One question to always ask: name the single most useful question a manager can ask in a one-to-one and explain why it tends to reveal things the manager would not otherwise know.
</task>

<output_format>
- Failure modes: 3 bullets, each naming the pattern and its effect
- 30-minute structure: 4 to 5 sections with time allocation and a sentence on the purpose of each
- Best question: 1 sentence with a 2-sentence explanation
- Tone: practical, grounded in real management situations
