Chevron's 52,000 employees work for thirteen major operating companies in 180 countries. Each national unit does business according to the needs of its market. Effective management of human resources in such a complex environment is an enormous task, and the key to success is reliable, accurate management information. Thus, Chevron developed an online human resources information system, which is a critical tool in managing its human resources. As expected, one of the broad goals of the human resources information system is to help management a. prepare specific job or position descriptions. b. develop a replacement chart. c. utilize human resources efficiently to meet organizational goals. d. send greetings to employees on their birthdays. e. write a job specification for the computer programmer.
