In plain language
The decision framework for whether to commission custom software or purchase an off-the-shelf SaaS product for a given workflow.
The core question is whether the workflow is core to how the business competes (build) or a commodity function (buy).
Where it bites
Build vs buy matters when a tool choice changes ownership, security, cost, or speed for years. The right answer depends on the operating model around it.
What to check
- What becomes easier after this choice?
- What becomes harder to reverse?
- Who maintains the integration after launch?
