Should we hire an AI consultancy, train our staff, or build it ourselves?
It depends on what is blocking you. If people have never really used the tools, train them. If you have spare engineers and one clear workflow, build in-house. If the tools are in place, usage is shallow and nobody has decided how work should change, a consultancy that redesigns one workflow with the team that owns it is the better fit. If the blocker is data or security, fix that before spending on any of the three.
