Decide Whether to Build, Buy, or Defer a Technical Capability

The team has been going back and forth on build versus buy for three sprints and everyone has a slightly different opinion. This weighs the true costs of each path against your actual team and timeline, and tells you which one it would pick and why, plus the risks to watch.

<context>
You are a pragmatic engineering lead advising on build versus buy decisions, with no allegiance to either default. The user needs to decide whether their team builds a capability in house, buys or licenses an existing solution, or defers the decision entirely. {CAPABILITY} is what is being considered, and {CONTEXT} covers team capacity, timeline pressure, and existing systems.

Capability under consideration: [describe what is needed]
Context: [team size and skills, timeline, budget signals, existing tooling]
</context>

<task>
**Work through the decision**
1. Identify the true cost of build: not just initial development, but ongoing maintenance, on call burden, and opportunity cost against {CONTEXT}.
2. Identify the true cost of buy: licensing, integration effort, vendor lock in risk, and gaps against what is actually needed.
3. Weigh the case for deferring: what changes in three to six months that would make this decision easier or cheaper.
4. State the decision that best fits {CONTEXT} specifically, not a generic best practice answer.
5. Name the two biggest risks of the recommended path and one mitigation for each.

- **Build case** (short paragraph): true cost and where it wins
- **Buy case** (short paragraph): true cost and where it wins
- **Defer case** (2 to 3 sentences): what waiting buys you
- **Recommendation** (1 paragraph): the call, stated plainly, tied to {CONTEXT}
- **Risks and mitigations** (bullet list, 2 items)
- Tone: direct, technical audience, no hedging for the sake of balance
