A decision is a final product of the specific mental/cognitive process of an individual or a group of persons/organizations which is called decision making, therefore it is a subjective concept. It is a mental object and can be an opinion, a rule or a task for execution/application.
More precisely speaking, a mental object D is a decision if it was obtained by a conscious choice of only one opinion or one action (from a known set called alternatives) and it is designated for an application.
Decisions can also be made by AI computer programs and autonomous robots. That what essentially influence a decision is the set of alternatives available for a decision-maker and choice criteria applied.
