Product Discovery

产品发现

Product discovery is the ongoing practice of learning what to build before - and while - building it. The goal is to reduce risk: shipping the wrong thing is far more expensive than the research that would have prevented it. This skill covers Jobs-to-be-Done (JTBD), opportunity solution trees, assumption mapping, experiment design, and prototype testing - giving an agent the judgment to run rigorous discovery the way a senior product manager or product trio would.

产品发现是一种持续实践，指在开发产品之前及开发过程中，学习应该构建什么内容。其目标是降低风险：推出错误的产品比通过研究避免这种错误的成本要高得多。此技能涵盖Jobs-to-be-Done（JTBD）、机会解决方案树、假设梳理、实验设计和原型测试——让Agent能够像资深产品经理或产品三人组一样，严谨地开展产品发现工作。

Key principles

核心原则

Discover continuously, not in phases - Discovery is not a gate before delivery. It runs in parallel with shipping. Every sprint produces both validated learning and working software. "Done with discovery" is a warning sign.
Outcomes over outputs - The goal is a measurable change in customer behavior, not a feature shipped. Define success as a behavioral outcome first; the solution is just a hypothesis about how to reach it.
Test assumptions, not ideas - Every solution idea rests on a stack of assumptions. Surface the riskiest ones first and test those - not the idea in its entirety. This collapses validation time by 10x.
Smallest experiment possible - Always ask: "What is the cheapest, fastest way to learn whether this assumption is true?" A 5-minute interview, a smoke test, or a paper prototype can invalidate months of engineering work.
Dual-track: discovery and delivery in parallel - One track discovers the next problem worth solving; the other delivers on already-validated solutions. Teams that separate these into sequential phases go dark on learning for months at a time.

持续发现，而非分阶段进行——产品发现不是交付前的关卡，它与产品交付并行推进。每个冲刺既要产出经过验证的认知，也要交付可用的软件。“完成产品发现”是一个危险信号。
成果优先，而非产出——目标是实现可衡量的用户行为变化，而非推出某个功能。首先将成功定义为行为成果，解决方案只是实现该成果的假设。
测试假设，而非想法——每个解决方案想法都基于一系列假设。先找出风险最高的假设并进行测试，而非测试整个想法。这能将验证时间缩短10倍。
尽可能最小化实验——始终问自己：“验证这个假设是否成立的最廉价、最快的方式是什么？”一次5分钟的访谈、一个烟雾测试或一个纸质原型，就能避免数月的无效工程工作。
双轨并行：发现与交付同步——一条轨道探索下一个值得解决的问题；另一条轨道交付已验证的解决方案。如果将这两个环节拆分为先后阶段，团队会在数月内无法获得新认知。

Core concepts

核心概念

JTBD Framework

JTBD框架

Jobs-to-be-Done treats customer behavior as hiring a product to do a job. The canonical JTBD statement is:

"When [situation], I want to [motivation], so I can [expected outcome]."

Jobs have three layers:

Functional job - The practical task (file my taxes quickly)
Emotional job - How the customer wants to feel (confident I won't get audited)
Social job - How they want to be perceived (look responsible to my partner)

Strong solutions address all three layers. Most competitors only address the functional job, leaving emotional and social value uncaptured.

Interview for jobs by asking about the last time the customer did the relevant behavior - not hypotheticals. "Tell me about the last time you..." surfaces actual pull, struggle, and workaround data.

Jobs-to-be-Done（JTBD）将用户行为视为“雇佣”产品来完成某项任务。标准的JTBD表述为：

“当[场景]时，我想要[动机]，以便[预期成果]。”

任务包含三个层面：

功能性任务——实际要完成的工作（快速完成报税）
情感性任务——用户希望获得的感受（确信自己不会被审计）
社会性任务——用户希望给他人留下的印象（在伴侣面前显得有责任心）

优秀的解决方案会覆盖这三个层面。大多数竞争对手只关注功能性任务，忽略了情感和社交价值。

开展任务访谈时，要询问用户最近一次做出相关行为的经历——而非假设性问题。“告诉我你最近一次……的经历”能挖掘出真实的需求、痛点和权宜之计。

Opportunity Solution Trees

机会解决方案树

The opportunity solution tree (OST) - developed by Teresa Torres - is a visual tool that maps the path from a desired outcome to the experiments that test candidate solutions.

Desired Outcome
  +-- Opportunity 1 (unmet need / pain / desire)
  |     +-- Solution A
  |     |     +-- Assumption 1 --> Experiment
  |     |     +-- Assumption 2 --> Experiment
  |     +-- Solution B
  |           +-- Assumption 3 --> Experiment
  +-- Opportunity 2
        +-- ...

Key rules:

The root is always an outcome (metric), never a solution
Opportunities are discovered from customers - not invented in the office
Each solution sits below a single opportunity - never jump to solution without an opportunity
Every solution has at least one assumption being actively tested

机会解决方案树（OST）由Teresa Torres提出，是一种可视化工具，用于梳理从期望成果到验证候选解决方案的实验路径。

Desired Outcome
  +-- Opportunity 1 (unmet need / pain / desire)
  |     +-- Solution A
  |     |     +-- Assumption 1 --> Experiment
  |     |     +-- Assumption 2 --> Experiment
  |     +-- Solution B
  |           +-- Assumption 3 --> Experiment
  +-- Opportunity 2
        +-- ...

关键规则：

根节点始终是成果（指标），而非解决方案
机会来自用户——而非团队在办公室凭空构想
每个解决方案仅对应一个机会——绝不能跳过机会直接跳到解决方案
每个解决方案至少有一个正在被积极测试的假设

Assumption Types

假设类型

Every product bet rests on four categories of assumptions:

Type	Question it answers	Example
Desirability	Do customers want this?	"Users want to share playlists with non-subscribers"
Viability	Can we make money from it?	"Enterprise customers will pay $50/seat for SSO"
Feasibility	Can we build it?	"We can infer intent from existing event data"
Usability	Can customers use it without friction?	"Users can complete onboarding without a tooltip"

Prioritize assumptions by: risk x proximity to a decision. Test the assumption that, if wrong, would kill the bet - before testing assumptions about optimization.

每个产品赌注都基于四类假设：

类型	要解答的问题	示例
Desirability（吸引力）	用户是否想要这个？	“用户希望与非订阅者共享播放列表”
Viability（可行性/盈利能力）	我们能从中获利吗？	“企业客户愿意为单点登录（SSO）支付每席位50美元”
Feasibility（技术可行性）	我们能构建出来吗？	“我们可以从现有事件数据中推断用户意图”
Usability（可用性）	用户能否无障碍使用？	“用户无需提示就能完成注册流程”

按风险×决策相关性对假设进行优先级排序。先测试那些如果不成立就会直接毁掉整个赌注的假设——而非优化层面的假设。

Experiment Hierarchy

实验层级

From lowest to highest fidelity and cost:

Assumption audit - List and stack-rank assumptions; no customer contact yet
Secondary research - Existing data, competitor analysis, academic studies
Customer interview - 30-60 min; 5-8 participants for a theme to emerge
Survey - Quantifies frequency of a qualitatively discovered pattern
Smoke test / landing page - Measures real intent without building the feature
Wizard of Oz - Manual fulfillment behind a product interface
Prototype test - Simulates the experience at chosen fidelity (paper, lo-fi, hi-fi)
Concierge MVP - Deliver the value manually; learn the job deeply
Technical spike - Validate feasibility assumption with a time-boxed build
A/B test / live experiment - Measures actual behavior change in production

See

references/experiment-playbook.md

for templates by assumption type.

按保真度和成本从低到高排序：

假设审计——列出并排序假设；尚未接触用户
二手研究——现有数据、竞品分析、学术研究
用户访谈——30-60分钟；5-8名参与者就能呈现出明显趋势
调研问卷——量化定性研究发现的模式出现的频率
烟雾测试/落地页——无需构建功能就能衡量真实意图
绿野仙踪测试——在产品界面背后手动完成服务交付
原型测试——以选定的保真度（纸质、低保真、高保真）模拟产品体验
礼宾式MVP——手动交付价值；深入理解用户任务
技术探索——通过时间盒式开发验证技术可行性假设
A/B测试/线上实验——在生产环境中衡量实际的行为变化

Common tasks

常见任务

Conduct JTBD interviews

开展JTBD访谈

Framework (45-60 min):

Recruitment - Screen for people who have recently done the behavior you're studying. Recent = within 90 days. Avoid future-intent screening questions.
Timeline reconstruction (20 min) - "Walk me through everything that happened from the moment you first realized you needed [solution category] to the moment you made a decision." Map: first thought, passive looking, active looking, deciding.
Dig into the struggle (15 min) - "What had you tried before? What was unsatisfying? What almost made you not switch?"
Outcomes and anxieties (10 min) - "What were you hoping would be different? What were you worried might not work?"
Wrap (5 min) - "If you could change one thing about [product], what would it be?" Use sparingly - this is ideation, not discovery.

Output: Job stories, struggle patterns, and switch triggers. Theme across 5+ interviews before drawing conclusions.

框架（45-60分钟）：

招募——筛选最近90天内有过相关行为的用户。避免询问关于未来意向的问题。
时间线重构（20分钟）——“请告诉我从你首次意识到需要[解决方案类别]到做出决策的整个过程。”梳理：首次想法、被动关注、主动寻找、做出决策。
深挖痛点（15分钟）——“你之前尝试过什么？哪些地方不满意？什么因素差点让你放弃更换？”
成果与顾虑（10分钟）——“你希望有什么不同？你担心哪些地方可能行不通？”
收尾（5分钟）——“如果你能对[产品]做一项改动，你会改什么？”谨慎使用——这是创意构思，而非产品发现。

**输出：**任务故事、痛点模式和转换触发因素。在5次以上访谈后再总结趋势，得出结论。

Build an opportunity solution tree

构建机会解决方案树

Start with the outcome - Name the metric the product trio owns this quarter, e.g., "Increase week-2 retention from 42% to 55%."
Generate opportunities from interview data - Each opportunity is an unmet need, pain, or desire expressed by a real customer. Do not invent opportunities in workshops.
Cluster and name - Group related struggles. Name them as customer problems ("I lose context when switching devices"), not solutions ("add cross-device sync").
Select the focus opportunity - Use impact/confidence/ease to compare. Pick one.
Brainstorm solutions - Generate 3+ candidate solutions per opportunity. Quantity over quality at this stage. Include unconventional ideas.
Map assumptions per solution - For each candidate, list what must be true for it to work. Sort by type (desirability/viability/feasibility/usability).
Design one experiment per risky assumption - Smallest test that could change your mind. Assign owner and timeline.

从成果开始——明确产品三人组本季度负责的指标，例如：“将第二周留存率从42%提升至55%。”
从访谈数据中挖掘机会——每个机会都是用户表达的未被满足的需求、痛点或愿望。不要在工作坊中凭空创造机会。
聚类并命名——将相关痛点分组。以用户问题的方式命名（“我在切换设备时会丢失上下文信息”），而非解决方案（“添加跨设备同步功能”）。
选择重点机会——使用影响力/信心/易用性维度进行比较。选择一个重点机会。
头脑风暴解决方案——每个机会至少生成3个候选解决方案。此时追求数量而非质量，包括非常规想法。
为每个解决方案梳理假设——列出每个候选解决方案成立所需的前提条件。按类型（吸引力/盈利能力/技术可行性/可用性）分类。
为每个高风险假设设计一个实验——设计足以改变你想法的最小测试。分配负责人和时间线。

Map and prioritize assumptions

梳理并优先排序假设

Use a 2x2 matrix: Certainty (known vs. unknown) x Risk (low vs. high).

High risk, low certainty - Test immediately. These are bet-killers.
High risk, high certainty - Monitor. You believe these but should revisit if evidence shifts.
Low risk, low certainty - Research when convenient. Won't kill the bet.
Low risk, high certainty - Ignore for now.

For each risky assumption, write a falsifiable statement: "We believe X. We will know this is true when we see Y. We will know it is false when we see Z."

使用2×2矩阵：确定性（已知/未知）× 风险（低/高）。

高风险、低确定性——立即测试。这些是会毁掉赌注的关键假设。
高风险、高确定性——持续监控。你认为这些假设成立，但如果有新证据出现，需重新评估。
低风险、低确定性——方便时再研究。不会影响赌注的成败。
低风险、高确定性——暂时忽略。

对于每个高风险假设，撰写可证伪的陈述：“我们认为X成立。当我们观察到Y时，说明假设成立；当我们观察到Z时，说明假设不成立。”

Design validation experiments

设计验证实验

Match the experiment type to the assumption category:

Assumption type	Preferred experiment	Signal to look for
Desirability	Customer interview, smoke test	Pull signals + click-through rate
Viability	Pricing interview, willingness-to-pay study	20%+ "definitely would pay" at target price
Feasibility	Technical spike, data audit	Can be built within X sprints
Usability	Usability test (think-aloud)	Task completion rate, errors, time-on-task

Every experiment needs: hypothesis, method, sample size, success criterion, and a kill threshold - the result that would lead you to abandon the bet.

See

references/experiment-playbook.md

for detailed templates.

根据假设类型匹配实验类型：

假设类型	推荐实验	关注信号
吸引力	用户访谈、烟雾测试	需求信号+点击率
盈利能力	定价访谈、支付意愿研究	20%以上用户“肯定愿意”支付目标价格
技术可行性	技术探索、数据审计	能在X个冲刺内完成构建
可用性	可用性测试（出声思考法）	任务完成率、错误率、任务耗时

每个实验都需要：假设、方法、样本量、成功标准，以及终止阈值——即会让你放弃赌注的结果。

Run prototype tests

开展原型测试

Choose fidelity based on what you're testing:

Fidelity	Best for	Tools
Paper / sketch	Flow and information architecture	Pen, Balsamiq
Lo-fi wireframe	Navigation and content hierarchy	Figma (no styling)
Hi-fi mockup	Visual design and emotional response	Figma, Framer
Coded prototype	Interaction quality, performance perception	Storybook, CodeSandbox
Production feature	Behavior change, retention, conversion	Feature flag in prod

Think-aloud protocol: Brief the participant ("we're testing the design, not you"), ask them to narrate thoughts as they navigate, do not hint or help, note confusion and errors, debrief after each task. Five participants reveal ~85% of usability issues.

根据测试目标选择保真度：

保真度	适用场景	工具
纸质/草图	流程和信息架构	笔、Balsamiq
低保真线框	导航和内容层级	Figma（无样式）
高保真原型	视觉设计和情感反馈	Figma、Framer
可交互代码原型	交互质量、性能感知	Storybook、CodeSandbox
生产环境功能	行为变化、留存率、转化率	生产环境中的功能开关

出声思考协议：向参与者说明“我们在测试设计，不是在测试你”，请他们在操作时说出自己的想法，不要提示或帮助，记录困惑和错误，每个任务完成后进行复盘。5名参与者就能发现约85%的可用性问题。

Synthesize discovery insights

综合产品发现洞察

Structure synthesis as: observation - pattern - insight - implication.

Observation - What one customer said or did (raw data)
Pattern - What appeared across multiple customers (theme)
Insight - Why this pattern exists (interpretation)
Implication - What it means for the product (decision input)

Avoid jumping from observation to implication. The missing middle is where discovery adds value over anecdote.

Affinity mapping: Write each observation on its own sticky. Group silently. Name groups as customer problems, not solutions. Rank by frequency and intensity of pain.

按以下结构整理洞察：观察-模式-洞察-启示。

观察——单个用户的言行（原始数据）
模式——多个用户身上出现的共性（趋势）
洞察——该模式存在的原因（解读）
启示——对产品的意义（决策输入）

避免从观察直接跳到启示。中间的模式和洞察环节，正是产品发现相比零散轶事的价值所在。

亲和图法——将每个观察写在单独的便签上，无声分组。以用户问题而非解决方案的方式命名分组。按痛点出现的频率和强度排序。

Create a discovery cadence for the team

为团队建立产品发现节奏

A sustainable cadence for a three-person product trio (PM, designer, engineer):

Cadence	Activity	Time
Weekly	2-3 customer interviews or usability sessions	2-3 hrs
Weekly	Assumption review: what did we learn, what changed?	30 min
Bi-weekly	OST review: update tree with new opportunities and learnings	1 hr
Monthly	Opportunity prioritization: re-rank based on new evidence	1 hr
Quarterly	Outcome review: did we move the metric? What next?	2 hrs

Talking to 2-3 customers per week compounding over a year creates an insurmountable understanding advantage over teams that research in batches.

三人产品团队（产品经理、设计师、工程师）的可持续节奏：

节奏	活动	时间
每周	2-3次用户访谈或可用性测试	2-3小时
每周	假设复盘：我们学到了什么，哪些假设发生了变化？	30分钟
每两周	OST复盘：用新机会和认知更新机会解决方案树	1小时
每月	机会优先级排序：根据新证据重新排序	1小时
每季度	成果复盘：我们是否推动了指标增长？下一步计划？	2小时

每周与2-3名用户交流，一年下来，团队对用户的理解会远超那些批量开展研究的团队。

Anti-patterns

反模式

Anti-pattern	Why it's harmful	What to do instead
Big-bang discovery	6-week research phase before a project; team goes dark on learning during delivery	Embed 2-3 interviews per week alongside shipping; discovery never stops
Solution-first OST	Listing features at the root of the tree instead of an outcome	Always start with a measurable outcome metric; solutions are hypotheses
Validation theater	Running research to confirm a decision already made; cherry-picking supporting quotes	Write a kill threshold before the study: the result that would change your mind
Over-fitting to one customer	Pivoting strategy based on feedback from a single vocal customer	Require a pattern across 5+ independent sources before changing direction
Premature high-fidelity	Pixel-perfect prototypes before validating the core job	Match fidelity to the assumption; paper prototypes can kill 80% of bad ideas cheaply
Skipping feasibility	Testing only desirability; engineering discovers a blocker in sprint 3	Include an engineer in discovery; run a technical spike for any novel feasibility assumption

反模式	危害	替代方案
一次性大规模发现	项目前开展6周研究；交付阶段团队无法获得新认知	在交付工作中每周嵌入2-3次访谈；产品发现永不停止
以解决方案为核心的OST	树的根节点是功能而非成果	始终以可衡量的成果指标为起点；解决方案只是假设
验证式表演	开展研究只是为了确认已做出的决策；挑选支持性的言论	在研究前设定终止阈值：即会让你改变想法的结果
过度拟合单个用户	基于某个活跃用户的反馈调整整体策略	需在5个以上独立来源中发现相同模式，再调整方向
过早使用高保真原型	在验证核心任务前就制作像素级完美的原型	根据假设匹配保真度；纸质原型能以低成本排除80%的糟糕想法
忽略技术可行性	仅测试吸引力；工程团队在第3个冲刺才发现技术障碍	让工程师参与产品发现；对任何新的技术可行性假设开展技术探索

Gotchas

注意事项

Recruiting interviewees through your own app produces selection bias - Users who respond to an in-app recruitment banner are your most engaged advocates. They will tell you the product is great and suggest incremental improvements. To discover why users churn or never activate, you must recruit from people who did not engage - churned users, trial non-converters, and target-persona non-users. Use external recruitment panels for discovery that needs unbiased signal.
Opportunity solution trees built in workshops produce solutions disguised as opportunities - When teams generate the OST collaboratively in a room, "opportunities" are often features rephrased as problems ("users want a better export experience" is a solution frame, not an opportunity). Real opportunities come from verbatim customer language captured in interviews, not from workshop sticky notes. Build the OST from interview data, not from team hypotheses.
Smoke tests measure intent to click, not willingness to pay or actual use - A high click-through rate on a "coming soon" landing page is a desirability signal, not a conversion signal. Users who click are curious; they have not committed to changing behavior, paying, or integrating the feature into their workflow. Smoke tests invalidate "no one wants this" but do not validate "people will pay and retain."
Using a high-fidelity prototype for flow testing anchors users on visual design - When a prototype looks production-ready, participants comment on button colors and copy instead of navigating authentically and revealing flow problems. For testing information architecture and navigation, deliberately use lo-fi wireframes. Reserve hi-fi prototypes for testing emotional response and design quality.
Kill thresholds defined after the experiment results are in are rationalization, not rigor - If you decide what "failure looks like" after you see the data, you will unconsciously set the threshold to preserve your preferred conclusion. Write the kill threshold - the specific metric result that would cause you to abandon or pivot the bet - in the experiment design document before the study begins.

通过自有应用招募受访者会产生选择偏差——响应应用内招募横幅的用户是最活跃的支持者，他们会称赞产品并建议增量改进。若要了解用户流失或从未激活的原因，必须从不活跃用户中招募：流失用户、未转化的试用用户、目标 persona 的非用户。对于需要无偏差信号的产品发现，使用外部招募平台。
工作坊中构建的OST会将解决方案伪装成机会——当团队在会议室协作构建OST时，“机会”往往是被重新包装成问题的功能（“用户想要更好的导出体验”是解决方案视角，而非机会）。真正的机会来自访谈中记录的用户原话，而非工作坊的便签。基于访谈数据而非团队假设构建OST。
烟雾测试衡量的是点击意图，而非支付意愿或实际使用行为——“即将推出”落地页的高点击率是吸引力信号，而非转化信号。点击的用户只是好奇，并未承诺改变行为、付费或将功能融入日常工作。烟雾测试能排除“没人想要这个”的可能，但无法验证“用户会付费并留存”。
用高保真原型测试流程会让用户关注视觉设计——当原型看起来像生产环境的产品时，参与者会评论按钮颜色和文案，而非真实操作并暴露流程问题。若要测试信息架构和导航，刻意使用低保真线框。仅在测试情感反馈和设计质量时使用高保真原型。
实验结果出来后才定义终止阈值是合理化解释，而非严谨验证——如果在看到数据后才决定“失败是什么样的”，你会无意识地调整阈值以保留自己偏好的结论。在实验开始前，就在实验设计文档中写下终止阈值——即会让你放弃或调整赌注的具体指标结果。
