Artifact has some interesting meanings, but the meanings seem to have in common some connection to the physical world of objects, or at least of observable things. Simple tools or other kinds of objects, like objects found at an archeological site would be called artifacts. Artifact can refer to body characteristics that have no functional value; I think the appendix would qualify. The word can also refer to something like non-harmful blips in an electrocardiograph that might come from some extraneous energy source. In these senses, organisation would be hard to class as an artifact. Organisation is more a concept than an artifact. However, you might get away with saying that organisations are artifacts of a certain age, or culture, or econony-- that kind of thing. But a good editor would probably discourage this use.
Leo made some great Artifacts. They are still very famous today.
