What system development life cycle phases did Jeannine skip? There are 5 phases to the systems development life cycle (SLDC). They are plan, analyze, design, implement, and support. Arguably Jane did some planning, some analyzing, no real design, and some implementing, although she did them poorly. She did not perform any support to the information system. Her planning began with a formal request to the IT department. However, she then gave up on the IT department. She did not follow through on this phase which would have been when the IT department did a further investigation into the feasibility of her request. Jeannine appears to have done her own feasibility study in a vacuum. In analysis, the IT department works to build models of the system requirements. Jane did her own analysis without others involvement. Because she did not include others, she did not include recent changes to company policy. For system design, Jeannine relied upon a computer store sales person rather than design a system herself. Relying upon commercially available software is an acceptable solution in some situations. b. What were the consequences of her actions to skip these phases? Because Jeannine did not do a proper analysis with involvement from other departments in the company, she missed out on significant requirements, e.g. changes to company policy and strategy, subordinates requiring graphic reports, etc.. While buying a commercially available system is fine in some situations, here, Jeannine was not prepared to buy an adequate system because of not fully grasping the requirements and business processes. What appeared initially to be a cost and time saving system acquisition will end up costing the company more because of the expense of repairing this system or acquiring or developing a second system. c. Why do think people today fall prey to the belief that the system development life cycle for an application is somehow different when using microcomputers or an off-the-shelf smart device, such as an iPhone? 1

In Jeannine’s situation, she saw a quick fix. It sounds as thought Jeannine bought the computer and system with either her own money or company money that she had discretion to spend. This is generally much faster than going through a formal approval process. Additionally, many of the stores and software companies have very good marketing programs. She was probably able to try the software out, get familiar with it, and in her mind, saw a rapid solution to a problem using software she understood.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    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.
