positive feedback loops and negative feedback loops (control processes)

1. Beth, the administrative assistant, continues to have headaches. Using the ideas of positive feedback loops and negative feedback loops (control processes), comment on what Beth could do to relieve these headaches. The treatment options could include medications and how the employee responds to those, adjustment of the lighting within the work site, sound, smell, etc. Also comment on non-medicinal therapies that might be available for this employee.

2. The communication of the message from the man to the machine is one factor to be considered. The other factor is the communication of the responding message from the machine to the man. Consider the word processor (i.e., Microsoft Word) you are currently using. In an essay, discuss how you are commanding the machine to do certain things and how the machine is responding to the commands. Discuss how this could go wrong and what could be done to prevent a failure from occurring. If the machine fails, how do you ensure that the work is completed?

3. The amount of information can sometimes hamper the outcome expected by the end user. In other words, clutter can hinder the intended message. One example of clutter (or too much information) is prescription-drug packaging. Explain why it is important for ergonomics professionals to understand the concept of clutter or “too much information”. Your response should be at least 200 words and site references.

4. Communication is a key factor to successfully completing a task, especially if others are involved in the task completion. In an essay, discuss the items that can go wrong with a communication system. Discuss the elements of a communication system and what the ultimate impact might be due to some sort of failure. Your response should be at least 200 words and site references.
