Unit-demand forecasting The vunit (which can be an entire department,a project team,or some other group of employees)forecast is a bottom-up approach to forecasting demand. Headquarters sums these unit forecasts,and the result becomes the employment forecast. The unit manager analyzes the person-by-person,job-by-job needs in the present as well as the future.By analyzing present and future requirements of the job and the skills of the incumbents,this method focuses on quality of workers.
In larger organizations,an HR executive at headquarters who is responsible for the employment demand forecast will improve the estimates by checking with the managers in the field. If the units forecast their own needs,the HR executive would sum their estimates to arrive at the forecast.
