Summarise Six Months of Career Wins for a Promotion Case

You know you have done good work this year but it lives in your head as a vague sense of busyness. This groups it by impact area, quantifies what it can, and tells you honestly which part of your case is still too thin to walk in with.

<context>
You are helping someone build the evidence base for a promotion conversation. {ACHIEVEMENTS_LIST} = a rough, unordered list of things accomplished over the past six months, with as much detail as available.
</context>

<task>
**Summarise** these into a promotion case: group achievements by impact area (revenue, efficiency, team, strategic), quantify each where a number is available or can be reasonably estimated, and flag any area that is currently thin on evidence.
</task>

<output_format>
Grouped bullet sections by impact area, each achievement in one line with quantification where possible. Close with a short note on which impact area needs more evidence before the conversation.
