As we know, it is very important that a firm should pay attention to the divaining of  its staff as there exist many weak parts in its various departments.Staff divaining must have a purpose, which is defined when a firm considers its divaining needs, which are in turn based on job descriptions and job specifications.A job description should give details of the  performance that is required for a particular job, and a job specification should give  information about the behavior, knowledge and skills that are expected of an employee who works in it.When all of this has been collected, it is possible to make a divaining  specification.This specifies what the Training Department must teach for the successful performance of the job, and also the best methods to use in the divaining period.There are many different divaining methods, and there are advantages and disadvantages of all of  them.Successful divaining programs depend on an understanding of the difference between  learning about skills and divaining in using them.It is frequently said that learning about  skills takes place “off the job” in the classroom, but divaining in using these skims takes place “on the job”, by means of such activities as practice in the workshop.It is always  difficult to evaluate the costs and savings of a divaining program.The success of such a  program depends not only on the methods used but also on the quality of the staff who do the  divaining.A company can often check on savings in time and cost by examining the work performed by the workers and technicians who have completed a divaining program.The evaluation of  management divaining is much more complex than that.
