Answer by alpha b
*Systems Development Life Cycle (SDLC) adheres to important phases that are essential for developers, such as planning, analysis, design, and implementation, and are explained in the section below. There are several Systems Development Life Cycle Models in existence. The oldest model, that was originally regarded as “the Systems Development Life Cycle” is the waterfall model: a sequence of stages in which the output of each stage becomes the input for the next.

What are the employment outlook for people majoring in “information system”?

Question by Fuentes: What are the employment outlook for people majoring in “information system”?
I would like to know how the future is for people who are majoring in: Business Administration emphasis in Information System. I read articles online and on the paper and they all say that people majoring in information system is a bad idea. Mostly because they don’t know what it is. I don’t know what it is or what kind of work they do.

There’s one article that says that people with a bachelor’s in Information System have a 13% unemployment rate and that number will go higher in the future. I want your opinion and honesty of how the outlook for people with that degree is. Is there job security in the near future (2-3 years from now) or should it be recommended that people should major in something else. If people continue to pursue with that degree how would an undergrad or recent graduate get an internship? Please be honest (brutally honest), I might be influenced with what you say.

Answer by Richard L
I majored in Computer Information Systems (CIS) and there are a variety of directions that you can go with this career. If the 13% unemployment rate number is correct that is not bad considering the actual US employment rate is probably approaching a real number of almost 20%.

If you like Technology then this is a good degree. If you are not sure what the degree is about you need to research that before you pour money and time into getting this degree. I’ve given you a list of jobs that would be possibilities for a CIS (or eqivalent degree) graduate.

Answer by Chief02
This is part of the System Development Life Cycle. The analysis phase comes after the Planning phase. (Planning, Analysis, Design, Implementation) System Analysis is the process of studying and understanding the current system in place, then coming up with the documents and ideas of the new system. Design includes the actual building of the new system.
