IB Business IA Proposal 选题 研究问题 详解
IB Business Management 的内部评估(IA)是很多同学冲 7 分时最容易被低估的一环。考试型题目套路清楚，IA 却要求你独立完成选企业、提问题、找证据、做分析的全流程，评分维度也更细。这篇文章给出一套可复用的写作流程：先把 Proposal 阶段的选题、研究问题与核心概念一次做对，再沿 1800 词的正文框架稳步推进，最后附上常见失分点与上交前的检查清单。
The IB Business Management internal assessment is one of the most underestimated routes to a 7. Exam questions follow predictable patterns, but the IA asks you to choose a real organisation, frame a research question, gather evidence and run analysis on your own, against a detailed rubric. This guide gives you a repeatable workflow: get the proposal stage right first (business choice, research question, key concept), then build the 1800-word commentary section by section, and finish with the common mark-losing mistakes and a pre-submission checklist.
新考纲框架: 1800词 25分 真实企业研究
自 2024 年 5 月首考的新大纲起，Business Management 的 SL 与 HL 内部评估要求完全一致：一份不超过 1800 词的 commentary，满分 25 分，研究对象必须是一家真实企业或非营利组织。全文主要依靠 3 到 5 份支撑文档来回答一个研究问题，问题还必须落在 change、creativity、ethics、sustainability 四个核心概念之一的框架内。从最终成绩占比看，SL 的 IA 权重约为三成，HL 约为两成，但写作任务本身没有差别。
Under the new syllabus first examined in May 2024, the Business Management IA is identical for SL and HL: a commentary of no more than 1800 words, marked out of 25, based on a real organisation, whether a business or a non-profit. You answer one research question using mainly 3 to 5 supporting documents, and the question must sit inside one of the four key concepts: change, creativity, ethics or sustainability. The IA carries roughly 30 percent of the SL grade and around 20 percent for HL, but the writing task itself is the same.
给一个可执行的时间节奏：选题与 RQ 打磨一到两周，期间同步联系企业约访谈；拿到初步数据后花两周完成三个工具的分析初稿；再用一周写评估与结论、整理附录文档。Proposal 在动笔写正文前定稿，正文只是把它兑现。千万别把访谈约在截止前一周，一手数据拿不到时整套设计都要返工。
A workable rhythm: spend one to two weeks on the business choice and RQ while contacting the firm to arrange an interview; once preliminary data arrives, take two weeks to draft the analysis across three tools; then use one week for the evaluation, conclusion and appendix documents. Finalise the proposal before you start writing the commentary, and let the commentary simply deliver it. Never schedule interviews for the week before the deadline, because losing primary data sends the whole design back to the drawing board.
选题定盘: 真实企业与问题 双向匹配 避开 EE 撞车
IA 的第一道分水岭是选对研究对象。理想企业要同时满足三个条件：第一，你有渠道拿到一手或可靠二手信息，本地社区里的咖啡馆、奶茶店、健身房往往比上市公司更好写；第二，企业当前确实面临一个可讨论的经营问题，例如外卖占比上升但利润下滑；第三，问题与你感兴趣的核心概念挂钩。注意不要与 Business Management EE 用同一家企业，否则选题视角会互相污染，两边都吃亏。
The first dividing line is your choice of organisation. The ideal subject meets three tests: you can actually obtain primary or reliable secondary information (a local cafe, milk-tea shop or gym is usually easier than a listed multinational); the firm currently faces a discussable business issue, such as rising delivery share but falling profit; and the issue connects to a key concept you care about. Do not reuse the same organisation as your Business EE, because the two projects will contaminate each other's angle and both will suffer.
Research Question 打磨: To what extent 句式与单概念约束
研究问题决定 IA 的生死。最高频的高分句式是 To what extent should X do Y to achieve Z，例如 To what extent should Green Bean Cafe introduce a reusable cup deposit scheme to strengthen its sustainability and customer loyalty。三个要素缺一不可：明确的企业主体、具体的行动方案、可检验的经营或概念目标。反面典型是把 RQ 写得过宽，例如 How does marketing work，这种问题既没有企业也没有行动，工具无处安放，分析必然散架。
The research question decides everything. The highest-scoring pattern is To what extent should X do Y to achieve Z: for example, To what extent should Green Bean Cafe introduce a reusable cup deposit scheme to strengthen its sustainability and customer loyalty? Three elements are essential: a named organisation, a concrete course of action, and a testable business or conceptual goal. The classic failure is an over-broad question such as How does marketing work, which has no firm and no action, leaving your tools with nowhere to land and your analysis without a spine.
研究问题的打磨一般要走三轮：第一轮写现象层问题，例如 How can Green Bean Cafe improve profit；第二轮把行动具体化，加上押金方案与目标，例如 To what extent should Green Bean Cafe introduce a reusable cup deposit scheme；第三轮补上核心概念与可测结果，得到完整版本。每一轮修改都问同一个问题：这个版本需要哪些工具和数据来回答？答不上来就继续收窄。
Polish the RQ in three rounds. Round one is a phenomenon-level question such as How can Green Bean Cafe improve profit; round two makes the action concrete by adding the deposit scheme and a goal, for example To what extent should Green Bean Cafe introduce a reusable cup deposit scheme; round three adds the key concept and a measurable outcome to reach the final version. After every round, ask the same question: which tools and data does this version need? If you cannot answer, narrow it again.
同时记住单概念约束：整份 IA 只能用四个核心概念中的一个作为分析透镜。如果你在 RQ 里塞进第二个概念，例如把 culture 或 globalisation 也写进去，概念维度的评分会直接归零，这是最容易白丢的 5 分。选定 sustainability 就把其他概念词汇从正文里清出去，只让它们作为背景事实出现。
Remember the single-concept constraint: the whole IA uses only one of the four key concepts as its analytical lens. If your RQ drags in a second one, such as culture or globalisation, the concept criterion can be zeroed outright, which is the easiest 5 marks to throw away. Once you choose sustainability, remove other concept vocabulary from your body text and let them appear only as background facts.
工具搭配: SWOT STEEPLE 决策树 用透两三个
工具是 IA 的骨架，但堆砌是低分捷径。判卷老师希望看到 2 到 3 个工具被真正用透，每个工具做完都要回到 RQ 回答 so what。SL 与 HL 共用的工具包括 SWOT、Ansoff 矩阵、STEEPLE、BCG 矩阵、决策树、描述性统计(均值、中位数、图表)与循环商业模式；力场分析、甘特图、Porter 通用战略、贡献成本法、关键路径分析等属于 HL 专属工具，SL 用了反而可能被判定超出大纲。
Tools form the skeleton of the IA, but piling them up is a fast route to low marks. Markers want two or three tools genuinely used to depth, each one returning to the RQ with a so-what conclusion. Tools shared by SL and HL include SWOT, the Ansoff matrix, STEEPLE, the BCG matrix, decision trees, descriptive statistics (mean, median, charts) and circular business models. Force field analysis, Gantt charts, Porter's generic strategies, contribution costing and critical path analysis are HL-only; using them in an SL submission can be judged outside the syllabus.
回到咖啡店案例：RQ 问的是换环保杯方案值不值得做，那么 STEEPLE 负责扫清外部环境(塑料税、消费者观念)，决策树把不确定的收益与成本算成期望值，客户问卷的数据用描述性统计呈现，三者层层咬合，正好覆盖环境、财务与需求三个侧面。选工具的第一原则不是难，而是与 RQ 的相关性。
Back to the cafe example: the RQ asks whether the reusable cup scheme is worth doing, so STEEPLE scans the external environment (plastic taxes, consumer attitudes), a decision tree converts uncertain revenues and costs into expected values, and questionnaire data appears through descriptive statistics. The three tools interlock and cover the environmental, financial and demand sides. The first rule of tool choice is relevance to the RQ, not difficulty.
支撑文档筛选: 3到5份 三年内 多元可靠五页内
支撑文档是新大纲 IA 的证据核心。硬性门槛有六条：距提交日不超过三年；彼此来源多元，最好覆盖不同立场；来自可靠出处；每份不超过五页 A4；不能是课本或课堂笔记；需要高亮你引用的部分，非英文材料还要附上关键段落翻译。一手资料(店主访谈、客户问卷、焦点小组)与二手资料(年报、新闻报道、公司官网)可以混用，也可以全部用一手。问卷与访谈必须附上空白问卷和回答汇总，方便考官核对你的分析。
Supporting documents are the evidence core of the new IA. Six hard rules apply: published no more than three years before submission; diverse in origin, ideally covering different viewpoints; from reliable sources; five A4 pages or shorter; never your textbook or class notes; and highlighted, with key passages translated if the document is not in English. Primary sources (owner interviews, customer questionnaires, focus groups) and secondary sources (annual reports, news articles, company websites) can be mixed, or you can go all-primary. Surveys and interviews need a blank copy plus a summary of responses so the examiner can check your analysis.
数量上 3 到 5 份刚刚好。太少撑不起三个工具的数据需求，太多则每份都浅尝辄止。筛选时反过来想：每份文档能为哪个工具提供什么数字或事实？如果一份文档除了提到企业名字外什么都给不了，果断换掉。
Three to five documents is the right range. Too few cannot feed three tools with data; too many and each one gets skimmed. Filter in reverse: what number or fact can this document supply, and for which tool? If a document mentions the firm's name and nothing else useful, drop it without hesitation.
以咖啡店案例为例，问卷回收 168 份有效回复：74% 的常客愿意支付 3 元押金租用环保杯，62% 每周到店三次以上，只有 9% 明确反对。这三个数字分别支撑决策树的收益估计、需求规模判断与风险分析，一份文档就喂饱两个工具。反过来，如果一份访谈记录通篇只有店主对行业的感慨，没有任何可量化或可核实的信息，它就不配占 5 份名额之一。
In the cafe case, 168 valid questionnaires came back: 74 percent of regulars would pay a 3 yuan deposit for a reusable cup, 62 percent visit three or more times a week, and only 9 percent object outright. These three numbers feed the decision tree's revenue estimate, the demand-scale judgement and the risk analysis, so one document can satisfy two tools. Conversely, if an interview transcript holds only the owner's general reflections with nothing quantifiable or verifiable, it does not deserve one of your five slots.
Proposal 五要素与正文写作闭环
很多学校会要求先交一页 Proposal 供老师反馈，即使不强制，写一份也能逼你把研究设计想清楚。一份合格的 Proposal 包含五要素：企业背景与选题理由(为什么这家企业、为什么这个问题，理由要落在企业利益而非个人兴趣)；研究问题与所选核心概念；计划使用的 2 到 3 个工具及各自作用；数据收集方法(访谈谁、问卷发给谁、二手数据看哪些)；以及时间表与风险预案，例如访谈被拒时改用公开财报。
Many schools require a one-page proposal for teacher feedback before the commentary. Even when optional, writing one forces you to think the research design through. A sound proposal has five elements: business background and rationale (why this firm and why this question, framed around the firm's interests rather than your own); the RQ and chosen key concept; the 2 to 3 tools planned and the job of each; the data collection methods (who to interview, who gets the questionnaire, which secondary data to read); and a timeline with contingency plans, such as switching to published accounts if an interview falls through.
正文的写作顺序建议为：介绍企业与 RQ，简述方法与概念透镜，逐工具展开分析与数据，每个工具后都给出初步判断，最后综合各工具结论回答 RQ，并诚实评估局限性，例如样本量小、数据为某单一时点、建议未考虑实施成本。评估部分的分量常常是 6 分与 7 分的分界线，考官要看到你质疑自己的证据，而不是只列优点。
For the commentary itself, write in this order: introduce the firm and RQ, outline the method and conceptual lens, then work through each tool with its data, giving an interim judgement after every tool, and finally synthesise the conclusions to answer the RQ with an honest evaluation of limitations, such as a small sample, a single point in time, or implementation costs left out. The evaluation section is often the line between a 6 and a 7, because examiners want to see you questioning your own evidence, not just listing strengths.
常见失分点与上交前检查清单
综合多年评分反馈，失分集中在五个模式：RQ 太宽或无法用企业数据回答；用了两个及以上核心概念；工具与数据脱节，摆出图表却不解释；支撑文档超过三年或来自不可靠出处；结论只复述分析结果而没有评估。对照这五条，写完后从考官视角通读一遍自己的文章，比多改十遍措辞更有用。
Across examiner feedback, marks are typically lost in five patterns: an RQ that is too broad or unanswerable with firm data; two or more key concepts used at once; tools disconnected from data, with charts shown but never explained; supporting documents older than three years or from shaky sources; and a conclusion that restates the analysis instead of evaluating it. Reading your own draft once from the examiner's chair beats ten rounds of polishing wording.
上交前最后检查一遍：字数是否在 1800 词以内并标注清楚；RQ 与概念是否出现在标题页；3 到 5 份文档是否全部附在文末并高亮；问卷与访谈汇总是否齐全；图表是否编号且有解读；引用是否完整可追溯。把 Proposal 阶段的功夫下足，正文只是把设计兑现，IA 拿高分就不再靠运气。
Before submission, run the final checklist: word count within 1800 and clearly stated; RQ and concept on the title page; all 3 to 5 documents attached and highlighted; survey and interview summaries included; every chart numbered and interpreted; every citation traceable. Put the hard work into the proposal stage and the commentary simply delivers the design, so a top IA grade stops depending on luck.
