Assessment of Quality Control of Tiles Production in West Africa Ceramics Company, Ajaokuta, Kogi State

Abstract

Tiles industries has a mandate to comply with total quality management (TQM) process through Standard Organization of Nigeria (SON) for compliant with ISO-9001 certification process for continuous improvement on control, assuring and managing of quality process. The quality tiles require quality performance in industry and it is one of the major issues facing implementation of TQM in industry due to crucial process involved. The study assessed total quality management for producing tiles in WACC, Ajaokuta, Kogi State using ISO-9001:2015. Quality controls of the tiles were assured using P-chart, operation characteristics curve and mechanical resistance test. The performance level of TQM is assessed using correlation approach. Findings of study revealed that TQM in WACC using ISO-9001:2015 Standard indicated implementation level of 71% in year 2022. ISO- 9001 based PDCA indicated 69.4% implementation of total quality management on continual project improvement. The compliance rating, P regression equation was: P= 4.75x+ 57.33 in which x is year after implementation of ISO 9001:2015. The six major tiles produced by WACC, Ajaokuta require maximum range of 0 to 3 defectives per daily batch production. The operating characteristic curve (OCC) showed that consumers are willing to none defective tiles of 40 x 80, 60 x 60, 120 x 60, 40 x 40, 25 x 40, 30 x 40 sq. cm. The study concludes that continuous improvement of quality standard implementation in WACC, Ajaokuta will boost the performance of tiles management and production.
