What's imprecise about: "Performant: 1) meeting the objective, often applied to a performance objective, 2) productive"? In looking around just now, economics

What's imprecise about: "Performant: 1) meeting the objective, often applied to a performance objective, 2) productive"? In looking around just now, economics seems to prefer the second definition, which is why I added it. All of the uses I found are compatible with this definition. What's the definition of "object oriented" again?
