Resumo: This paper aims to evaluate stability and quality guarantee of the productive process regarding soluble coffee plant situated in the state of Paraná. The collected sample contents 4.598 observations of weight of 50 and 100 grams cans. The process of collection was made automatically during period of October 8th and December 5th 2004. ARIMA model’s residues were evaluated by the cumulated sum control charts (CUSUM) with “V” mask form, which showed that productive process is statistically unstable. This is evinces fragility of the process regarding the guarantee for the products that do not comply with requirements, mainly the weight of the 50 grams’ containers. The results suggest that employees should have more accurate attention to the discipline and control of everyday activities, besides banning mistakes made by them on the routine work that can be solved with the right orientation and changing equipment adjustment procedures. Key Words: ARIMA, Cumulated Cum Control Charts (CUSUM), Soluble Coffee Productive Process.

A amostra coletada corresponde a 4.598 observações do peso de latas de 50g e 100g de café instantâneo em pó, sendo realizada de forma computadorizada no período de 8 de outubro a 5 de dezembro de 2004. Os resultados auferidos, com base nos resíduos provenientes dos modelos autoregressivos de terceira ordem (ARIMA), foram avaliados com base na carta de controle de somas acumuladas (CUSUM) a qual evidenciou um processo produtivo instável estatisticamente, o que corrobora com uma fragilidade do processo no que tange à garantia de produtos não conformes, principalmente quanto ao peso dos vasilhames de 50g. Os resultados apresentados propõem maior atenção por parte dos funcionários da indústria de fabricação de café, dispensando maior disciplina e controle nas atividades realizadas no dia-a-dia, além de permitir dizimar importantes erros cometidos na rotina de trabalho e que podem ser solucionados com boa orientação e mudança de comportamento no que tange à regulagem e manutenção dos equipamentos.
