I kindof disagree. For example while studying UML, it became more and more apparent to me how legitimate it is to have the word "science" in "Computer Science". Being able to create a high-level framework that is general enough to apply pervasively to IT systems is not a trivial matter, and requires considerable academic effort and creativity. The domain may be different from biology or physics, but the methods of obtaining that"understanding" you mention are strikingly similar (which accounts for the reliability of the results that are delivered).
