故事 · IDEO 与三个圆
Origin Story · IDEO and the Three Circles
设计公司 IDEO(设计过苹果第一只鼠标、第一台笔记本)一直被一个问题困扰:为什么有些惊艳的设计最后死掉了?
CEO Tim Brown 给出答案:好创新不是单点最强,而是三件事同时成立 —— 用户想要(Desirability)、
技术做得到(Feasibility)、生意算得过来(Viability)。他把它画成三个交叠的圆,
唯有正中央那一小块交集,才是值得砸资源的「创新甜区」。
很多团队栽在只顾一个圆:工程师沉迷技术(做得出但没人要),老板紧盯利润(赚得到但用户嫌弃),
设计师只谈情怀(用户爱但公司赔钱)。三透镜的全部价值,就是逼你同时戴上三副眼镜看同一个点子。
IDEO — the firm behind Apple's first mouse and first laptop — kept running into the same question:
why do some stunning designs still die?
CEO Tim Brown gave a simple answer: great innovation isn't about being best on a single axis,
it's about three things being true at once — people want it (Desirability),
we can build it (Feasibility), and the numbers add up (Viability).
He drew it as three overlapping circles, and only the small patch in the dead center is the sweet spot worth pouring resources into.
Most teams die clinging to one circle: engineers chase technology (built but unwanted),
executives chase margins (profitable but resented), designers chase delight (loved but bleeding cash).
The whole point of the three lenses is to force you to wear all three pairs of glasses on the same idea at the same time.

昙花一现Flash in the Pan
需求 × 商业,缺可行性。用户想要、能赚钱,但技术撑不住,做出来也维持不久。
Desirability × Viability, missing Feasibility. Users want it and the math works, but the tech can't hold up — it ships, then collapses.
技术自嗨Engineering Vanity
可行 × 商业,缺需求性。技术炫、账面好看,但用户根本不想要,叫好不叫座。
Feasibility × Viability, missing Desirability. The tech is sharp and the spreadsheet glows, but nobody actually wants it — applause without buyers.
做慈善Running a Charity
需求 × 可行,缺商业性。用户爱、也做得出,但不赚钱,烧光钱就关门。
Desirability × Feasibility, missing Viability. Users love it and you can build it, but it doesn't pay — burn the runway, close the doors.
3 现实里的三透镜 Three Lenses in the Real World
创新甜区:三圆交集才值得投入。评审一个点子先问:用户要吗、做得到吗、赚得到吗,缺一即危。
The sweet spot: only the triple overlap deserves real investment. Before greenlighting an idea, ask all three — do users want it, can we build it, can it pay? Miss one and you're already at risk.
需求×可行×商业:三副眼镜分别由用户研究、技术团队、商业模型来佩戴,缺哪副就请哪方进场。
Desirability × Feasibility × Viability: each lens has its rightful wearer — user research, engineering, and the business model. Whichever pair is missing, pull that team into the room.
IDEO 框架:源自 IDEO 与斯坦福 d.school,是产品立项、投资评审最常用的三问清单。
IDEO framework: born at IDEO and Stanford's d.school — the three-question checklist that powers most product greenlights and investor diligence today.
避免单点突破:别因为「技术最牛 / 利润最高 / 用户最爱」就上马,单点强而其余空缺照样死。
No single-axis wins: "best tech," "highest margin," or "users love it" is not enough on its own. A peak on one axis with gaps on the others still dies.
一句话In One Line
人和组织都有「偏科」的本能:工程团队会把方案往可行性圆里拉,财务会往商业性圆里拉,设计师往需求性圆里拉。
每一方都觉得自己那个圆最重要 —— 于是点子被扯向某个圆的边缘,离中心甜区越来越远。
三透镜的本质,是给团队一个共同的裁判标准:不管你来自哪个部门,一个点子只有落进正中央的交集才算数。
它不会告诉你怎么把圆做大,但它会无情地照出你缺的那个圆 —— 而那个缺口,往往就是项目早晚会死的地方。
记住:创新不是某一项做到极致,而是三件事都刚好够。
People and organizations have a built-in bias: engineers tug the idea toward Feasibility, finance pulls it toward Viability, designers lean it toward Desirability.
Each side is convinced their own circle is the one that matters — so the idea drifts to the edge of one lens and away from the center.
The real job of the three lenses is to give the team a shared referee: no matter which department you come from, an idea only counts if it lands inside the patch in the very middle.
It won't tell you how to grow any one circle, but it will mercilessly expose the one you're missing — and that gap is almost always where the project eventually dies.
Remember: innovation isn't about maxing out one axis — it's about all three being good enough at the same time.
常见误用Common Mistakes
只看一个圆就拍板(技术最强 / 利润最高)。三圆同时成立才上马,单点突破最容易栽。
Greenlighting on a single circle ("best tech," "highest margin"). Ship only when all three hold at once — single-axis bets fail most reliably.
把三透镜当一次性评分表,立项后就丢。全程反复校验,随着信息更新,缺的圆会变化。
Treating the three lenses as a one-shot scorecard, then shelving it after kickoff. Re-run the check throughout the project — which circle is missing will shift as you learn.
三个圆都自己脑补,不请对应方进场。需求问用户、可行问技术、商业问财务,证据各有来源。
Imagining all three circles from inside one room, without inviting the right people. Ask users for Desirability, engineers for Feasibility, finance for Viability — each lens has its own source of truth.
