Earned Value Management a budżetowanie elastyczne kosztów projektu

The paper presents a comparison of Earned Value (EV) and Flexible Budgeting (FB) in terms of managing project cost. Key performance indicators of cost efficiency characteristic of both methods have been described. Similarities and differences in the approach to the interpretation of schedule variance with relation to base-line budget (EV) and volume variance with respect to static budget (FB) have been emphasized. The significance of budgeted cost of work performed (BCWP, i.e. the earned value) and first flexible budget (FB I) as well as the nature of cost variance in the EV method vs. usage variance and price variance in flexible budgeting have been discussed. Issues of ex ante estimate-to-completion in the earned value method and ex post analytical advantages of cost control of flexible budgeting have also been addressed. In order to enrich the comparison simulation data for a hypothetical project have been applied in the article.
