The need to manage quality to enhance process effectiveness through elimination of wastes is a pointer to sustainable productivity. The factors that are affecting process quality management were harnessed from industrial experts. Process Quality Effectiveness (PE) was analyzed using Traditional Effectiveness measure, and then using developed modified version by incorporating dynamism that can enable effectiveness measures through combination and isolation of quality factors (manpower, machine, material, energy, management, information / communication, money and marketing) simultaneously. Decision on process quality acceptability of a plastic company was made by comparing quality effectiveness measured with the universal quality standards (sustainable quality trend, global acceptable quality standard and industrial revolution quality class. The results indicated varying quality measures in isolation against combination. From the results, machinery factor was identified as the root cause of reduced process quality effectiveness and hence needs to be concentrated upon to enhance process quality effectiveness.
