Running head: SDLC 1The System Development Life Cycle for a System Upgrade Project at Pizza Palace Ashleigh Walker, Jessica Ybarra, Jeffrey DevriesCISP111 - Davenport University
SDLC2AbstractIn the System Development Life Cycle, SDLC, there are five stages. The SDLC is a type of structured analysis. Each stage is critical in the development and maintenance of software. The five stages are Systems Planning, System Analysis, System Design, System Implementation,and Systems Support and Security. The stages should be done in order and done completely to ensure a smooth project development cycle. Specifically, we will zoom into the components of each phase as they apply to a new system for an independent, small-town business known as Pizza Palace. We will consider the usage of CASE tools, which stands for Computer Aided Software Engineering, and how they can contribute positively to a project lifecycle.
SDLC3PlanningThe first step of the System Development Life Cycle is the planning stage. As the name may suggest this is the phase of any operation where the planning is done for later steps of a project. Scott Tilley says, in Systems Design and Analysis, “the systems planning phase usually begins with a formal request to the IT department, called a systems request, which describes problems or desired changes in an information system or a business process.” (Tilley. 2019). In order to create and submit a systems request, the business should define what it is they are looking to be implemented in the new system. The business for this case is a pizza place called Pizza Palace, located in a small town in the state of Michigan. In this stage tasks such as feasibility studies are performed inorder to ascertain whether a project is even possible. Technical feasibility, operational feasibility, and economical feasibility are all considered. “Once the project is approved, it enters project management. During project management, the project manager creates a work plan, staff the project, and puts techniques in place to help the project team control and direct the project through the entire SDLC. The deliverable for project management is a project plan, which describes how the project team will go about developing thesystem.” ("3 - SDLC Planning Analysis Design Implementation - ust-comp2-com", 2019). Things such as gantt charts, PERT/CPM charts, and network diagrams are researched and implemented during this search. These are also referred to as CASE tools, Computer Aided Software Engineering. One example of a CASE tool is visual paradigm. Visual paradigm is full of possibilities when it comes to CASE tools. They offer diagram tools, process modeling tools,
SDLC4project management tools, analysis tools, design tools, coding and database engineering, and more, all in one downloadable software. This would be useful because you can use the same software for the entire project instead of needing to switch to different programs through different phases of the SDLC. Another useful CASE tool is Project Manager through Microsoft.
