小型團隊如何以最低可行方式實施 NIST AI RMF
AI RMF for Small Teams: Minimal Viable Implementation
文章提出一套供小型團隊採用的 NIST AI RMF 最低可行實施方案，由一名負責人統籌 Govern、Map、Measure 和 Manage。方案包括逐項記錄 AI 系統的登記表、三級風險評級、風險處理清單及事故紀錄，並建議每月檢視。最小起步配置是一份登記表、一套評級標準和每月檢討，先運行兩個季度再逐步增加措施。

The Small-Team Problem
The NIST AI RMF looks like it assumes a large organization with dedicated risk, legal, and security staff. Most small and mid-sized teams do not have those resources. The good news: NIST explicitly designs the framework to be scalable and adaptable to organizational context and available resources (NIST, 2023). A minimal viable implementation capturing the essence of Govern, Map, Measure, and Manage can be run by a single accountable owner.
The goal is not to replicate a large enterprise program, but to build a lightweight, honest loop that catches the risks that actually matter. Smaller organizations disproportionately rely on a few key teams to carry governance — which makes simplicity and repeatability the priority.
A Minimal Govern
One accountable owner. Name one person who owns AI risk. Everything else flows from that.
One-page AI policy. Write a single page covering: what AI is and isn't allowed, who must approve deployments, and where the risk register lives.
A five-item risk appetite. Instead of a detailed appetite statement, write five plain sentences: what you accept, what you mitigate, what you never accept.
A Minimal Map
A one-row-per-system register. Keep a simple table (spreadsheet or Airtable) with columns for name, purpose, data, vendor, owner, and risk. Update it monthly.
Track shadow AI. Add a recurring question: "What AI did anyone adopt without approval this month?" A monthly email to the team surfaces tools the register is missing.
A Minimal Measure
A three-level rubric. Score each system Low / Medium / High on likelihood and impact, then combine. Three levels are enough for a small team to prioritize without drowning in nuance.
Likelihood — low rare / medium possible / high likely.
Impact — low minor / medium significant / high severe (harm, legal, money).
One baseline per system. Capture the system’s intended behavior and its current performance so you can notice when it drifts.
A Minimal Manage
A simple treatment list. For each medium/high risk, write the mitigation, the owner, and a due date. Review monthly.
An incident log. Keep a short log of anything that goes wrong — wrong outputs, data incidents, misuse. Note what happened and what you changed.
The Cadence That Makes It Stick
Monthly — reconcile register + review treatments — 30 min.
Quarterly — re-score systems, spot-check baselines — 1 hour.
Per deployment — approve new system, assign owner, log it — 30 min.
Annual — review the policy + appetite line by line — 1 hour.
Start Smaller Than You Think
The most common failure is over-scoping. A genuinely minimal start is: one register, one rubric, one monthly review. Run that for two quarters. Then add one element at a time — baselines, a formal treatment plan, or the GenAI profile's actions for your highest-risk system (NIST, 2024). Small, consistent beats ambitious and abandoned.
