value-chain-skill

value-chain-skill is a skill for Claude Code, Codex from peterfei/forge-skill. It costs 56 tokens per session (4,322 once invoked), scanned A, original, MIT.

A structured method for value-chain analysis, which examines the separate activities a business performs to create and deliver value. It uses those activities and their links to study where competitive advantage comes from.

In plain words
What is it for?
Use it to study a company’s cost structure, differentiation, business processes, supply chain, or competitive advantage.
Why use it?
It replaces broad claims about competition with a review of specific business activities, costs, and sources of customer value. It also shows how improving connected activities together can matter more than improving one activity alone.

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

value-chain-skill 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 3d 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.

价值链分析 · 思维工具

竞争优势不是来自单个活动,而是来自整个价值链的协调与优化。

激活条件与触发词

直接调用

  • "用价值链分析..."
  • "帮我做价值链分析"
  • "用 Porter 的价值链框架..."

语义触发

  • 用户询问企业如何获得竞争优势
  • 用户需要分析企业的成本结构或差异化来源
  • 用户讨论业务流程优化或活动协调
  • 用户分析行业价值链或价值系统

组合调用

  • "先用价值链分析再用 SWOT 分析"
  • "结合价值链分析和商业模式画布"

方法框架概览

价值链分析的核心是将企业分解为战略性活动,通过识别每项活动的成本与价值,发现竞争优势的来源。它通过5个基本原理来帮助企业理解如何在每个活动上创造价值并优化整体链条。

核心原理(5个,每个须附 ≥2 个跨域证据)

原理 1: 价值活动分解 — 将企业分解为可识别的独立活动

一句话定义:竞争优势存在于具体活动中,必须将企业分解为可分析和优化的独立活动单元。

跨域证据

  1. 制造业(Starbucks):Starbucks 通过优化"进货物流"(直接与咖啡农合作)和"运营"(门店体验设计)创造差异化优势。Porter 框架应用于咖啡零售业,识别出供应链和门店体验是关键价值活动。
  2. 家居零售(IKEA):IKEA 在"技术开发"(平板包装设计)和"出货物流"(扁平包装运输)上创新,显著降低成本。来源:DIVA Portal 学术论文"IKEA Value Chain Innovation"。
  3. 科技行业(Apple):Apple 将"技术开发"(芯片设计)和"采购"(供应链控制)作为核心价值活动,创造硬件生态优势。来源:Harvard Business School 案例。

应用方式:面对"企业如何获得竞争优势"问题时,不要泛泛而谈,而是将企业分解为进货物流、运营、出货物流、营销销售、服务、采购、技术开发、人力资源、基础设施九大活动,逐个分析。

局限:对于服务型企业或平台型企业,传统制造业的价值活动分类可能不适用,需要调整活动定义。

原理 2: 价值链链接 — 活动间的关联优化创造额外价值

一句话定义:活动的协调与优化比单个活动的优化更重要,因为关联可以创造复合价值。

跨域证据

  1. 制造业(Toyota):Toyota 通过"进货物流"(JIT 采购)与"运营"(精益生产)的链接,减少库存成本。来源:Porter 原著中关于价值链链接的阐述。
  2. 零售业(Walmart):Walmart 的"采购"(集中采购)与"进货物流"(配送中心)链接,结合"技术开发"(信息系统),实现成本领先。来源:HBS 案例。
  3. 失败案例(Kodak):Kodak 的"技术开发"(1975 年发明数码相机)未能与"营销"和"运营"链接,导致价值链断裂。来源:HBR 2016 "Kodak's Downfall Wasn't About Technology"。

应用方式:当分析企业优势时,不仅关注单个活动,还要识别活动间的链接(如采购如何影响运营,技术如何支持营销),并寻找优化机会。

局限:在快速变化的环境中,过度优化现有链接可能阻碍创新,需要平衡效率与灵活性。

原理 3: 价值系统定位 — 企业价值链嵌入更大的价值系统中

一句话定义:企业的竞争优势不仅来自内部价值链,还来自如何与供应商、渠道、买方的价值链链接。

跨域证据

  1. 科技行业(Apple):Apple 通过控制供应商(采购活动)和渠道(Apple Store),在整个价值系统中创造优势。来源:Porter "Competitive Advantage" 第 2 章。
  2. 零售业(Amazon):Amazon 的价值链延伸到第三方卖家(平台化)和消费者(Prime 会员),形成生态系统优势。来源:Wharton School 关于数字价值链的研究。
  3. 失败案例(Nokia):Nokia 专注于硬件制造(运营活动),忽视了与软件开发者、应用商店(渠道)的链接,失去生态优势。来源:ResearchGate 比较案例研究。

应用方式:当分析企业时,不仅要看内部活动,还要看其在供应商→企业→渠道→买方价值系统中的位置,寻找协同机会。

局限:小型企业可能对供应商和渠道的控制力有限,价值系统优化的空间受限。

原理 4: 成本与差异化驱动 — 每项活动都有成本和差异化潜力

一句话定义:竞争优势来自成本领先或差异化,每个活动都是成本或差异化的潜在来源。

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
