Having once bought the economic tiles of Benok Ceramics and Limited”, aims to apply statistical process control (SPC) technique as a quality control (QC) tool to production processes of Habila Food and Beverages Nigeria. 2.6 Distributions of data ………………………………………………………………………………………………. 5.3 Recommendations ………………………………………………………………………………………………….

One method, referred to as acceptance sampling, can be used when a decision must be made to accept or reject a group of parts or items based on the quality found in a sample. 40 49 1.8 Company Description at a Glance …………………………………………………………………………………….

This study is based on the fact that no industry will operate and continue its existence effectively without primary concern given to the application of statistical quality control. 3 Statistical quality control (SQC) is the use of statistical tools and techniques to monitor and maintain product quality in industries such as food, pharmaceuticals and many manufacturing environments.

The company is fully into the manufacture and distribution of quality fruit juices and non – alcoholic beverages ranging from Pineapple juice, Orange juice, Bottle and Sachet water, Yogurt, Sobo, and many more. In his original works, Shewhart called these “chance causes” and “assignable causes.” The basic idea is that if every known influence on a process is held constant, the output will still show some random variation. 28 ABSTRACT. Since the best way to control quality in any manufacturing/production or non- manufacturing industry is to „built-in quality‟ during the production process stages. Fortunately though, this dilemma is addressed by the application of Statistical Quality Control in measuring and evaluating the quality of the products.

Nigeria, but was restricted to Benok Ceramics and Trading Industry Onne, Eleme One of the major roles of the operations manager is to make sure his or her firm can deliver a quality product to the right place at the right time and with a right price (Douglas, 2009). The poor implementation of statistical quality Habila has nine (9) installed machines in fruit and juice section where this research work was carried out, well calibrated for filling bottles and cans drinks. 1.1Background tothe Study 2.2.8. It becomes increasing apparent that decision must be made on facts, not just opinions; consequently, data must be gathered and analyzed in order to help guild the decision making process and as such SPC technique would help in analyzing the process quality of Habila Food and Beverages Nigeria Limited so as to monitor the volume dispersion in the filling process.
