So if programming isn’t science or engineering, what is it? It’s a liberal art. Modern programming bears more similarity to creative writing than to engineering or physics. The design process that you go through (or at least should go through) to create a program is almost identical to the process that you use to write a book: research, formulating a thesis (or problem definition), an orderly exposition of the thesis. These steps are central to both expository writing and object-oriented analysis and design.
