Assignment 1 week 3 - Case Study Example

Couse: Assignment week 3 List the system requirements, with examples for each category. Review the information that Susan gathered, and assume that she will add her own ideas to achieve more effective outputs, inputs, processes, performance, and controls. Managing the system requires Personal Inc. to install the system that will handle many clients while providing graphic user interface for the staff. A system that ensures performance, controls, inputs and outputs and the process works with the minimum and recommended requirements to achieve the goals of the company (Tan and Nijholt 34).

Hardware and software requirements will be required to control the upgraded system. The hardware requirements include; Intel Core processor i5 version and aboveAt least a 4 GB RAM 2 GB space in hard disk DirectX 3.0 or higher DVD/CD-ROM Software requirements include; The platform i.e. Windows Operating System APIs and drivers Web browser Internet connection Are there scalability issues that Susan should consider? What are they? Working with new designs comes with scalability issues. The properties of systems should be able to accommodate the changes in the amount of data input.

Scalability issues are addressed mainly if the business anticipates expansion. Investing in such a business management system without anticipating growth remains a loss of the investment. The system should grow with the growth of the business. Paying for extra resources without the anticipation of growth should be considered while implementing the system. For the software requirements, the web server implemented should accommodate for valleys and peaks in user traffic (Tan and Nijholt 35). If Susan wants to conduct a survey of current or prospective members to obtain their input, what type of sampling should she use? Why? Multi-stage sampling is a method applicable in the case scenario of Personal Inc.

The population at the company is too large to perform a simple random sample. In the case information on the required system comes in various stages. At each stage of sampling, different aspects such as user level, department and shift will generate different programs. Draw an FDD that shows the main operations described in the fact statement.
