## Aliases
|
||
- TCO（供应链场景）：采购总拥有成本
|
||
- 全生命周期成本
|
||
|
||
## Total Cost of Ownership (TCO)
|
||
|
||
A financial framework used to evaluate the total cost of acquiring, operating, and maintaining a technology solution over its entire lifecycle, compared across different deployment options.
|
||
|
||
## Definition
|
||
TCO encompasses all direct and indirect costs associated with a technology investment, not just the upfront acquisition cost. In cloud migration and hybrid cloud contexts, TCO analysis is used to compare on-premises infrastructure against cloud-hosted solutions like VMware Cloud on AWS or native AWS services.
|
||
|
||
## Components
|
||
- **Acquisition Costs**: Hardware/software procurement, licensing, implementation
|
||
- **Operational Costs**: Staff, maintenance, support contracts, utilities
|
||
- **Infrastructure Costs**: Data center space, power, cooling, physical security
|
||
- **Hidden Costs**: Underutilization, downtime, technical debt, migration effort
|
||
- **Exit Costs**: Data transfer out, licensing cancellation, decommissioning
|
||
|
||
## Key Applications
|
||
|
||
### VMC on AWS TCO Analysis
|
||
- Cloud economics team performs TCO calculations for VMC on AWS vs. on-premises vs. native hyperscaler
|
||
- VMware sells entire hosts, enabling over-provisioning and cost reduction
|
||
- VMC on AWS offers 27% cost saving compared to going to a regular cloud
|
||
- Compare TCO with on-premises or other hyperscalers for informed migration decisions
|
||
|
||
### General Cloud TCO Considerations
|
||
- On-premises: CapEx heavy, but can have unused capacity (Micro Focus hardware utilization < 40%)
|
||
- Cloud: OpEx model, pay-as-you-go, but egress costs and lock-in risks
|
||
- Hybrid: Balances migration flexibility with gradual transition costs
|
||
|
||
## Supply Chain Procurement TCO
|
||
[[Supply Chain Strategist Agent]] 使用 TCO 作为采购决策的核心依据，而非单一比较单价。
|
||
|
||
### Cost Components in Procurement
|
||
- **直接成本**：单价采购价、工装模具费、包装费、运输费
|
||
- **间接成本**：检验费用、来料不良损失、库存持有成本、管理费用
|
||
- **隐性成本**：供应商切换成本、质量风险成本、交付延误损失、协调开销
|
||
- **全生命周期成本**：使用和维护成本、报废和回收成本、环保合规成本
|
||
|
||
### Decision Principle
|
||
> "While supplier C's unit price is 5% higher, their incoming defect rate is only 0.1%. Factoring in quality loss costs, their TCO is actually 3% lower." — [[Supply Chain Strategist Agent]]
|
||
|
||
- 战略型物料（[[Kraljic Matrix]]）：TCO 评估尤为重要，需综合考量质量风险和供应稳定性
|
||
- 采购决策必须综合考虑直接成本 + 间接成本 + 隐性成本，而非仅比较单价
|
||
- 关键物料宁可接受更高单价，也要确保供应安全（TCO 中隐含供应中断成本）
|
||
|
||
