IT 510 Module Five 1 Module Five covers the topic of object oriented (OO) design, which is the new methodology.

As with all traditional models, there are new, different models created that some think are a much more improved way to the old way. In Modules Four and Five, these distinctly different models are presented because a systems analyst should be agnostic to a design methodology. There are projects that benefit from using structured designs and projects that benefit from using OO design. Most organizations have standardized on structured design methods. Considering the years of investment put into the process, the training, and the document templates, transitioning to OO design is typically not a good financial decision, as it is a very costly transition. This is especially true since there is not a business case that supports OO design being more cost effective, providing better system designs, etc. than existing structured design. The OO design methodologies are prevalent in newer companies because OO was the current model used as newer companies began building the IT system analysis processes. Be aware, similar to many old and new ideas, there are strong opinions on both sides of the argument. There is not one specific right way.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
