Handbooks and manuals are also used in training programs, often in the form of tutorial or instructional guides. Here the object is not merely to document a process or procedure, but to actively teach something. Many policies, particularly those that have a direct impact on the employee and the company, may require follow-up training as well. Such topics might include sexual harassment policies and codes of ethics. Also, computer users may require in-class training on different functions of computer hardware and software. Thus, handbooks and manuals are integral parts of in-house training programs. There is seemingly no end to the number and types of documents needed to support a company's operations.
