What are you hiring for?
Most companies come to this decision with a symptom, not a job description. The board has asked for a plan. A pilot has run for a year with nothing to show. A vendor has quoted something expensive and no one inside can judge it. Start by naming which of the three jobs you need.
A decision
Which initiatives to fund, in what order, at what cost, and how you will know they worked. The output is a written verdict, not a deck of options.
A build
One system taken from a working pilot into daily use, with a number that moved and a person on your team who can run it.
Ownership
Someone senior to run the portfolio after the first system ships. The reviews, the build-or-buy calls, the report to the board.
The order matters. A build without the decision is how companies end up with a well-made tool nobody asked for. Ownership without a build is a retainer with nothing to own. If you cannot say which job you need, the first job is the decision.
