The Dewey Decimal Classification System was developed in order to make finding and classifying books within the library so much easier. Typically, there are hundreds of thousands of books within the library. And to make all of those books much easier to find. And to also make it easier for librarians to know where to place those books, the Dewey Decimal System was put in place. This kind of book organization system uses numbers from 000 to 999 to categorize the books into particular topics, so all of the shelves within most libraries have that kind of numbering.
5. Rethinking the Role of Analysts Analysis is a very important activity on any software development project, regardless of paradigm. It is an organizational design decision to define what roles you will have and what those roles will do. In traditional development there is often someone(s) in the role of analyst, and some organizations even choose to distinguish between analyst types and will have system analysts (SAs), business analysts (BAs), business system analysts (BSAs), data analysts, process analysts, and so on. In agile development we make different organizational design decisions. So, although we still perform analysis we haven't made the decision to have someone in that specific role.
