The classic technology question is framed as a binary: build it ourselves or buy it from someone else. Both answers commit money, attention and a maintenance burden that outlives the people who chose them. There is a quieter third option that rarely makes the slide: not yet.

When to wait

Waiting is the right call more often than roadmaps admit. If the process the system would support is still changing shape, any tool you pick will encode a version of the work you are about to abandon. A lightweight manual approach — a shared document, a clear owner, a weekly habit — buys you the understanding you need to choose well later, at a fraction of the cost of choosing now and being wrong.

When to act

Act when the work has stabilised, the volume genuinely hurts, and you can describe the job to be done without reference to a particular product. At that point, buy if the capability is common and well-served by the market, and build only where the way you do it is a real source of advantage. Building a commodity is how organisations acquire systems they must nurse forever.

Build, buy, or wait. Holding the third option open is usually what makes the first two good decisions when their time comes.
