strategy-two-tests

strategy-two-tests is a skill for Claude Code, Codex from ace3000chao/book2startup. It costs 124 tokens per session (3,762 once invoked), scanned A, original, MIT.

A two-question test for deciding whether a plan is a real strategy: does it matter to enough customers, and does it clearly differ from competitors?

In plain words
What is it for?
Use it to review company, product, or competitive strategies and test whether they create important customer value and genuine differentiation.
Why use it?
It separates a meaningful competitive approach from a general goal, product improvement, or plan that rivals can easily copy.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

strategy-two-tests scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Strategy Two Tests(战略必须通过两个测试)

R — 原文 (Reading)

"You don't have a real strategy if it doesn't pass two tests: First, what you're planning to do really matters to enough customers; and second, it differentiates you from your competition."

— Verne Harnish, Scaling Up, 第1章 (引用 Gary Hamel)


I — 方法论骨架 (Interpretation)

Gary Hamel(世界顶级战略大师)的定义:真正的战略必须同时通过两个测试

Scaling Up引用Gary Hamel的核心观点:大多数公司有的是"计划"、"目标"或"愿景",但不是真正的"战略"。Hamel认为,战略不是"我们要去哪里",而是"我们如何在竞争中赢"。

两个测试的定义:

测试一:对足够多的客户真的重要(Customer Mattering Test)

  • 一个战略必须对足够多的目标客户真的重要——不是"有点帮助",不是"还不错",而是"如果你没有这个,客户会非常不满意"
  • 这个测试的意图是防止"战略过于细分"(只对极少数客户有价值)或"战略过于泛泛"(对谁都没有真正吸引力)
  • 检验方法:问"如果我们停止做这件事,现有客户会怎样?"——如果答案是"他们会注意到并流失",说明这件事真的重要;如果答案是"他们可能不会发现",说明这件事根本不是战略

测试二:能差异化于竞争对手(Competitive Differentiation Test)

  • 一个战略必须让你在竞争中与众不同——不是"比竞争对手好一点点",而是"竞争对手如果不复制你这个,他们就无法与你竞争"
  • 这个测试防止"战略同质化"——你和竞争对手做的事情几乎一样,只有价格或执行力差异,那不是战略,是竞争
  • 检验方法:问"竞争对手最害怕我们做什么?"——如果答不出来,说明你可能没有真正的差异化战略

两个测试的关系:

  • 通过测试一但未通过测试二:你有"好的产品"但没有"战略"——竞争对手会慢慢蚕食你的优势
  • 通过测试二但未通过测试一:你有"差异点"但市场太小——无法支撑企业Scaling
  • 同时通过两个测试:真正的战略——既服务足够大的市场,又能差异化于竞争

常见的失败模式:

  • "我们有战略"但只通过测试一:产品/服务有价值但没有差异化,价格战或执行力竞争
  • "我们有战略"但只通过测试二:差异化足够但细分市场太小,无法支撑规模化增长
  • "我们有战略"但两个测试都没通过:空洞的计划,既没有客户真的在乎,也没有差异化

A1 — 书中的应用 (Past Application)

案例 1: 苹果的"测试一二通过"

  • 问题: 乔布斯回归后的苹果,PC市场份额始终在5%以下,但苹果在"个人电脑"市场仍然活着并繁荣。为什么?
  • 方法论的使用: 用两个测试检验苹果1998年后的战略——"让普通消费者能使用强大的个人计算设备"(测试一:对足够多客户真的重要?——是的,苹果的iMac和后来的iPhone瞄准的不是极客,而是大众消费者,他们真的在乎"易用性");"设计与用户体验作为核心竞争力"(测试二:差异化于竞争对手?——是的,戴尔和惠普都在用英特尔芯片和Windows,苹果用自己的芯片和操作系统,设计和体验是竞争对手难以快速复制的)。
  • 结论: 苹果的战略同时通过两个测试,所以是真正的战略。PC市场份额5%不是失败,而是苹果主动选择了小而精的市场(而不是大众市场),但战略本身仍然是服务足够大的人群(消费者市场的"高端")。
  • 结果: 苹果成为全球市值最高的公司之一,在乔布斯回归后20年内增长超过100倍。

案例 2: 西南航空的"测试一二通过"

  • 问题: 90年代,几乎所有大型航空公司都在枢纽-辐射网络模型(Hub & Spoke)中竞争,每家航空公司的战略几乎一样:覆盖尽可能多的城市,提供尽可能多的航班选择。西南航空则坚持"点对点"短途航线。
  • 方法论的使用: 用两个测试检验西南航空的战略——测试一:低成本短途直航对客户真的重要吗?(是的,对于短途旅客(2小时以内),直航比中转节省3-4小时,时间就是钱);测试二:这个战略差异化于竞争对手吗?(是的,枢纽-辐射航空公司无法在短途直航上与西南竞争,因为他们的成本结构(高劳动力成本、多机型切换成本)使短途直飞不经济)。
  • 结论: 西南航空的战略是真正的战略:它对足够多的客户(短途旅客)真的重要,且竞争对手即使看到了也无法复制(成本结构是结构性障碍)。
  • 结果: 西南航空连续47年盈利,是美国航空业历史上唯一一家没有破产的大型航空公司。
