The demo works beautifully. The invoice looks manageable. Then someone asks whether it connects to the system you actually use.<\/p>\n\n\n\n
This is where the build-or-buy decision becomes interesting.<\/p>\n\n\n\n
Do not compare the purchase price of a tool with the cost of writing a prototype. Compare the cost of operating a useful system.<\/p>\n\n\n\n
Write the input, desired output, frequency, users and important exceptions. List which systems must exchange information.<\/p>\n\n\n\n
For example: \u201cPrepare a reviewable summary of approved support tickets each Friday, grouped by product issue, with links back to the source.\u201d That is a requirement. \u201cWe need an AI platform\u201d is a shopping mood.<\/p>\n\n\n\n
Distinguish essential behaviour from preferences. This prevents an attractive feature list from rewriting the problem.<\/p>\n\n\n\n
For a purchased tool, include configuration, data cleanup, training, integration, monitoring and the time spent correcting results.<\/p>\n\n\n\n
For a custom tool, include ongoing model or infrastructure charges, testing, maintenance, security review and the person who answers when it fails.<\/p>\n\n\n\n
A prototype can be quick. A dependable service has a longer shopping list.<\/p>\n\n\n\n
Ask what happens when an input is incomplete, a connected system is unavailable or a result cannot be verified.<\/p>\n\n\n\n
Try representative awkward cases during evaluation. Do not let the vendor supply every example.<\/p>\n\n\n\n
Document which actions are reversible and which need human approval. If the tool can alter customer records, the evaluation must cover more than whether its summary sounds sensible.<\/p>\n\n\n\n
Can you export your data in a useful format? Can another person understand the configuration? What breaks if you cancel?<\/p>\n\n\n\n
For custom work, confirm access to source code, deployment instructions and operational documentation. For purchased software, understand the practical limits of portability.<\/p>\n\n\n\n
\u201cFuture-proof\u201d is not a specification. An exit plan is.<\/p>\n\n\n\n
Buy when the available product meets the important requirements and the operating costs make sense. Build when a genuinely distinctive workflow justifies ownership and maintenance.<\/p>\n\n\n\n
A hybrid can work: standard tools for ordinary functions, custom code for the narrow part that makes your operation different.<\/p>\n\n\n\n
Write down your assumptions and a review point. The decision can change as volume, risk and requirements change. Being willing to revisit it is good management, not an admission that the first meeting was insufficiently visionary.<\/p>\n\n\n\n
