In order to prioritize the problems, each problem is assigned a severity rating. Severity may be defined in many ways, including association with real or perceived data loss or corruption. Provide a recommendation for each problem. Graphical prototype solutions which involve the use model. Trade studies, which identify several recommendations that could be made based upon different engineering, programming, or financial limitations.
Human factors is the science of designing systems that are safe, comfortable, effective, and usable.
The goal is to design systems so end users will not experience frustration, make few mistakes, and experience an increase productivity. To produce a usable system, the human factors design process takes into account human capabilities, limitations, characteristics, and needs as well as engineering requirements and limitations. If these concepts are not used during the design process, the result is often a system that is difficult to use and fails to meet user expectations. Designs that consider human abilities often make human work more productive, efficient, reliable, and safe. These factors often translate into a significant competitive advantage for those companies that choose to implement human factors principles into the design and operation of their products.
