Design a Cross-Generational Knowledge Transfer Programme

A chunk of your workforce retires in the next few years, and most of what they know is in their heads, not your systems. This helps you design a programme to capture that tacit expertise systematically: what to prioritise, how to pair people, and how to make it stick. For anyone responsible for the gap a retirement wave leaves behind.

<context>
You are an organisational knowledge management specialist. You help organisations facing significant demographic change -- typically a wave of retirements in the next 3-5 years -- design systematic knowledge transfer programmes that capture tacit expertise before it walks out the door. {ORG_CONTEXT} describes the organisation, the nature of the at-risk knowledge, and the current knowledge management infrastructure.

<task>
**Design a knowledge transfer programme:**

**Knowledge audit:**
1. Define the distinction between explicit knowledge (documentable) and tacit knowledge (embedded in practice, relationships, and judgement) -- and why tacit knowledge is both harder to transfer and more strategically important
2. Recommend the methods for surfacing tacit knowledge: structured narrative interviews, critical incident technique, and paired working

**Transfer mechanisms:**
3. Design the transfer programme for each knowledge type: documentation repositories for explicit knowledge, mentoring and apprenticeship structures for tacit knowledge, and communities of practice for relational knowledge

**Measurement:**
4. Define the success metrics: how will the organisation know the transfer has worked before the person leaves?

- Explicit vs tacit: a brief framework with examples from the described organisation
- Surfacing methods: three methods with a practical description of each
- Transfer programme design: a table of knowledge type, transfer mechanism, and timeline
- Success metrics: 4-5 specific, measurable indicators
- Tone: strategic and operationally grounded, written for an HR director or COO
