Solution Preview

System Analysts build models because organizations rely on computer and information technology to conduct business and operate efficiently. They choose what model and technique to use in accordance with user need and help organizations to use technology effectively and to incorporate rapidly changing technologies into their existing systems. The work of computer systems analysts evolves rapidly, reflecting new areas of specialization and changes in technology.

Computer systems analysts solve computer problems and use computer technology to meet the needs of an organization. They may design and develop new computer systems by choosing and configuring hardware and software. They may also devise ways to apply existing systems' resources to additional tasks. Most systems analysts work with specific types of computer systems?for example, business, accounting, or financial systems or scientific and engineering systems?that vary with the kind of organization. Analysts who specialize in helping an organization select the proper system software and infrastructure are often called system architects. Analysts who specialize in developing and fine-tuning systems often are known as systems designers.

To begin an assignment, systems analysts consult managers and users to define the goals of the system. Analysts then design a system to meet those goals. They specify ...

Create A System Design Document

System Design is a critical phase of the system life cycle. Poorly designed systems often do not achieve the intended goals. The proper design of inputs, outputs and interfaces play a key roll in system success. The goal of the design phase is to create an interface that is intuitive, logical, and easy to use while achieving the operational goals for the system.

For this project, you will submit a System Design document in MS Word that includes the following:

A title page
A business letter introducing the contents of the document
A visual representation of your system interface. You can prepare this using a drawing package and embed the graphic or MS Word's drawing features. Your interface should include the main screen of your solution and show the main features.
A summary of the proposed program operation
A summary of the implementation plan timeline.
