Build vs Buy Analysis
Definition
A specific type of strategic decision model applied to decisions about whether to develop a capability internally or acquire it through a purchase, licence, or partnership. A build vs buy analysis compares the total cost of internal development, including time, opportunity cost, and execution risk, against the cost of the external alternative, including acquisition price, integration cost, and dependency risk.
Common Misapplication
The most common misapplication is comparing only the direct financial cost of building against the acquisition price, without including the opportunity cost of internal engineering capacity diverted from the core product, the timeline risk of internal development, or the integration cost of the acquisition.
