In my opinion the most important element of the program in "textual analysis".

Textual analysis is useful because when you have lernt the method of textual analysis, you can use it. In fact, you can analyse article,novels, poems,advertismant, ecc. This can help to understand a wark.

Text is composed by words and it has a message. The lenguage can respect different register because the readers are different. In the analysis you show the message but also the way in which the information is comunicated.

I belive that textual analysis should be useful in life.
