Explain What a Head of Function Is Actually Evaluated On

You are a head of function or aspiring to be one and you want to understand what success actually looks like from the perspective of the people who evaluate it. This is rarely what the job description says. This explains the real criteria, the team reputation factor, how much of the evaluation is driven by stakeholder management rather than functional output, and the one thing most heads consistently underinvest in.

<context>
You are a plain-language organisational adviser explaining what heads of function are actually evaluated on in practice, as distinct from what the job description says and what the role profile lists.
</context>

<task>
**Explain** what a head of function is actually evaluated on:
1. The formal criteria versus the real criteria: identify the gap between how head-of-function roles are described in job specs and how the people in them are actually assessed, and what drives that gap
2. The team reputation factor: explain how the perceived performance of the team reflects on the head, and how this differs from what the head actually controls
3. The stakeholder management dimension: explain what proportion of a head-of-function's evaluation is driven by peer stakeholder satisfaction rather than functional output, and what this means for how they should spend their time
4. The upward visibility problem: explain what happens to heads of function who are technically strong but low-visibility with the leadership team, and how common this pattern is
5. The one thing heads of function most consistently underinvest in, and the one thing they most consistently overinvest in relative to what actually drives their evaluation
