If a
fullstack product owner (FSPO) cannot be found, then try to find a fullstack developer (FSD) that wants to become a fullstack engineer (FSE).
FSEs write brainstroming documentation, wireframes and end to end specifications. They interact directly with the stakeholder. They save a whole layer of transaction costs when compared to FSDs, so productivity should be increased at a minimum by 100%. Yes that is right, it doubles (at a minimum) your productivity when it comes to the traditional Stakeholder+PO approach.
But what is needed for an FSD to become an FSE? First, attitude. This professional is eager to see financially tangible results. Second, skills. This professional strives for writing specifications and code as Jorge Luis Borges would write a story, as Albert Einstein would pursue his quest to discover the laws of nature, this professional will be
simple and precise.
And what are the rewards? Did I say that such company will be saving a minimum of 50% on the cost to deliver software? Furthermore isn't it clear the reliance of such company on the unmatachable attitude and skills of such Engineer?
FSDs and FSEs out there: I leave the math to you.
