Evaluation and control is necessary as considerable costs are incurred in the recruitment process. The costs generally incurred are:
1. Salaries for recruiters.
2. Management and professional time spent on preparing job description, job specifications, advertisements, agency liaison, and so forth.
3. Cost of advertisements or other recruitment methods, that is, agency fees.
4. Cost of producing supporting literature.
5. Recruitment overheads and administrative expenses.
6. Costs of overtime and outstanding while the vacancies remain unfilled.
7. Cost of recruiting suitable candidates for the selection process.
Questions should always be asked as to whether the recruitment methods used are valid and whether the recruitment process itself is effective. Statistical information on the cost of advertisements, time taken for the process, and the suitability of the candidates for consideration in the selection process should be gathered and evaluated. However, exercises seem to be seldom carried out in practice.
