This study primarily includes theoretical information on the performance and lost productive time of a firm. Furthermore t-shirt sewing operations of a garment firm were analysed and time measurement for each operation was carried out by the time keeping method. By considering the measurements obtained, different performance estimations, the firm’s lost productive time rates, and the standard time was calculated within 5 different scenarios. According to each sewing standard time obtained, the assembly line balancing practice was carried out using the Hoffman method. Later on results of the assembly line balancing were compared, and the importance of employee performance assessment and its lost productive time rates for firms were discussed. The aim of the study was to emphasize the value of impeccable determination of the employee performance assessment and lost productive time rates. Consequently garment firms will be more cautious in calculating the standard time and will be able to reach their production target within the accurate measurement they obtain.

W artykule przedstawiono przede wszystkim teoretyczne informacje o ocenie wydajności pracowników i utracie czasu produkcyjnego w przemyśle odzieżowym. Przeprowadzono analizę szycia koszulek dokonując pomiaru czasu dla każdej operacji. Na podstawie analizy otrzymanych wyników określono 5 różnych scenariuszy. Zrównoważenia linii produkcyjnej dokonano przy użyciu metody Hoffmana. Następnie porównano wyniki i omówiono znaczenie oceny wydajności pracowników i utraty czasu produkcyjnego. Zaprezentowana analiza może posłużyć firmom odzieżowym w skutecznym zaplanowaniu czasu produkcji i przyczynić się do terminowej realizacji zamówień, co pozwoli uniknąć dodatkowych kosztów spowodowanych opóźnieniem.
