In contrast to these relatively specialized HRISs, technology has also made it possible for organizations to integrate multiple HR needs into a single system. Apple Computer's system allows employees to enroll in benefit programs directly from their personal computers. Line managers can process traditional employee transactions such as pay increases, and they can use learning modules that instruct them in skill improvement programs such as conducting legal performance analysis. Chevron has also moved toward general systems. In 1986, the company had over 200 different HR systems, most of which couldn't communicate with one another. Now there is one system with data on all Chevron employees worldwide. The company estimates that it has saved nearly $2,000 per employee by removing these redundancies. And with over 50,000 employees, the saving have been substantial.
