Notes:
Because people usually feel uncomfortable when being watched, they may unwittingly perform differently when being observed. In fact, the famous Hawthorne Experiment proved that the act of observation can alter behavior
Some tasks may not always be performed in the manner in which they are observed by the systems analyst. For example, the systems analyst might have observed how a company filled several customer orders. However, the procedures the systems analyst observed may have been those steps used to fill a number of regular customer orders. If any of those orders had been special orders (e.g., an order for goods not normally kept in stock), the systems analyst would have observed a different set of procedures being executed.
