The acts of project(ion) / project acts or projacts

I am interested in the epistemological status of «project(ion)», that is, the «act» or «strategy» of project(ion) in relation to various didactic protocols usually associated with an «author» and her intention or production. What is a plan, program, plot, platform, concept, conception, or even «meta-project»? Is a project or projection necessarily an «architectural matter»? Is it a prototypically Western or European procedure of specific use of time and space (literally, throwing forth into space/time)? I will attempt to explain some passages from Eisenman, Cacciari, as well as a theory recently put forth by Armando and Durbiano (Teoria del progetto architettonico).
