A number of companies offer software for reviewing worker performance. Some offer technology that can be installed on computers within an organization. Others offer Web-based services. As a team, identify a couple of companies that offer electronic performance review technology. (Some company names you will likely run across in a computer search include Halogen, Workscape, and PerformanceReview.com.) For each company selected by your team, describe the performance review service that is provided. What claims do the vendors make with regard to the benefits their services provide? If possible, determine the typical cost associated with the use of the technology for a small or medium-sized firm. Estimate the per-employee cost of the electronic approach. Given your cost figures, do you think purchasing electronic review technology is something you would recommend to a small or medium-sized firm? Share your findings and conclusions with the rest of the class.
