It can be observed (Fig. 5) that the factor which determined the occurrence of most of the flaws analyzed
(missing sticker, sticker with air bubbles, incorrectly applied sticker, inadequate painting) was the human
resource, most flaws being identified as coming from the sticker application workshop and conveyor belt
handling of the flawed products from the supplier. The rest of the flaws were due to external factors, these
being easy to eliminate if measures are taken in due time. Regardless of the factor that led to the occurrence of flaws it was considered necessary to set specific working instructions specific for each production workshop
that takes into account the quality of individual execution of assignments.
