For Chapter 5 question 1: One of the potential problems mentioned in the chapter with gathering information requirements by observing potential system users is that people may change their behavior when observed. What could you do to overcome this potential confounding factor in accurately determining information requirements? (5 points)
There is no doubt that an employee may change their attitude or work behavior when they are being observed. One thing that I would do is keep observing the employee, however informing the employee before the observation would allow the employee to attempt to work with their best quality while being observe. This will allow the observer to identify the issues that the worker really has.
