Therefore, The present study examines the effect of effort and result-oriented contracts on the productivity of human resources in a 20,000-head state cattle farm in Iran. A comparative approach was used to investigate the effect of effort-based and result-based payments on human resource productivity. It analyzed ten projects in a set, where five were used for effort-based contracts and five similar projects used for results-based contracts. The findings of the study show that result-based contracts have a substantial impact on the productivity of labor in terms of effectiveness and efficiency.
