全球采购正在进入“多供应商时代”：企业如何设计第二来源策略？

##

第二来源并不意味着：

每一种产品都必须找两家工厂。

真正目标是：

**为最不能中断的产品，提前准备可以替代的供应路径。**

Deloitte调查中，74%的采购负责人将寻找替代供应来源视为最有效的供应链风险缓解策略。OECD的供应链韧性研究也强调供应多元化的重要性，并指出全面本土化并不必然提高韧性。

一、哪些产品需要第二来源？

优先考虑：

• 缺货会停产；
• 替代验证时间长；
• 单一材料；
• 专用模具；
• 长交期；
• 高收入贡献；
• 单一区域依赖；
• 安全关键零件。

二、第二来源有四种形式

同地区、不同工厂

切换成本低，但不能解决区域风险。

不同地区、相同工艺

降低地缘和物流集中风险。

不同材料、相同功能

降低原料风险。

不同设计、相同功能

韧性最高，但开发成本也最高。

三、Stellar第二来源优先模型

按照三个变量评分：

**Business Impact × Switching Difficulty × Disruption Risk**

每项1—5分。

第二来源预算应该首先投向高分产品。

四、“找到第二家工厂”不等于第二来源

备用供应商必须至少完成：

• 企业审核；
• 样品验证；
• 工艺验证；
• 商务条款；
• 小批量测试；
• 必要认证。

否则发生中断后才开始测试，只能称为候选供应商。

五、核心供应商不应把第二来源视为威胁

成熟供应商可以主动帮助客户：

• 建立安全库存；
• 提前预警；
• 开发备用材料；
• 提供替代物流；
• 支持海外库存。

这种能力反而会提高其战略价值。

成熟的多供应商体系不是无限增加供应商。

更合理的结构是：

**少数核心供应商＋关键品类备用来源。**

Second sourcing does not mean:

Finding two factories for every product.

The real goal is:

**Preparing alternative supply paths in advance for products that are least likely to experience disruptions.**

In a Deloitte survey, 74% of purchasing managers considered finding alternative supply sources the most effective strategy for mitigating supply chain risks. The OECD's supply chain resilience study also emphasizes the importance of supply diversification, pointing out that full localization does not necessarily improve resilience.

I. Which products need second sourcing?

Prioritize:

• Production stoppages due to stockouts;

• Long alternative validation times;

• Single material;

• Dedicated molds;

• Long lead times;

• High revenue contribution;

• Single-region dependence;

• Safety-critical components.

II. There are four forms of second sourcing:

Same region, different factories: Low switching costs, but cannot resolve regional risks.

Different regions, same process: Reduces geographical and logistical concentration risks.

Different Materials, Same Function

Reduces raw material risk.

Different Designs, Same Function

Highest resilience, but also highest development cost.

III. Stellar Second Source Priority Model

Scored according to three variables:

**Business Impact × Switching Difficulty × Disruption Risk**

Each item is scored from 1 to 5.

Second source budgets should be prioritized for high-scoring products.

IV. "Finding a Second Factory" Does Not Equal a Second Source

Backup suppliers must at least complete:

• Corporate audit;

• Sample verification;

• Process verification;

• Commercial terms;

• Small-batch testing;

• Necessary certifications.

Otherwise, if testing only begins after a disruption, the supplier can only be considered a candidate supplier.

V. Core Suppliers Should Not View Second Sources as a Threat

Mature suppliers can proactively help customers:

• Establish safety stock;

• Early warning;

• Develop backup materials;

• Provide alternative logistics;

Support overseas inventory.

This capability actually enhances their strategic value.

A mature multi-supplier system is not about infinitely increasing suppliers.

A more reasonable structure is:

**A few core suppliers + backup sources for key product categories.**
