Quality control (QC) is important not just in the production or transformation process, but earlier at the design stage and later at the service stage as well. Competition is one of the most important factors in running a business in the world economy today. There is a substantial return on investment from improved quality and from successfully employing quality as an integral part of overall business strategy. Trading Industry, I found out that some of their products were produced and Statistical process control (SPC) is a method of quality control which employs statistical methods to monitor and control a process. This research work title;“Application of Statistical Quality Control in Foods& Beverages Industry. It can be any store, really, as long as there are products that line the shelves or showroom. In a country like Nigeria where the culture of reading is not well developed and imbibed by individuals and organizations, there is a strong tendency that information (data) collected will contain errors of misrepresentation especially in a study of this nature where the information (data) sought concerns the internal and operational issues of an organization as it might be rightly or wrongly thought that divulging such information will be inimical to public judgment. The main objective of statistical quality control (SQC) is to achieve quality in production and service orga- nizations, through the use of adequate statistical techniques. 1.3 The Present Research Study 2.1.1 The Concept of Quality ………………………………………………………………………………………….. 14 Thorough coverage of statistical process control (SPC) demonstrates the efficacy of statistically-oriented experiments in the context of process characterization, optimization, and acceptance sampling, while examination of the implementation process provides context to real-world applications. 25 3.3.1 Data extracted for Can filler Machines from appendix A ……………………………………… 32 others. 40 Conformance to Standards ……………………………………………………………………………………. 46 The Importance of SPC ………………………………………………………………………………………….. 12 As part of its plans for expansion, the firm has procured a multi-million naira plant solely for the production of processed tomatoes and other food seasonings. tiles were taken in Ten (10) samples of size hundred (100) each from a lot to 1.7 Limitation of the Study 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.

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.

Douglas (2009) says, Quality is not just of concern in manufactured products, it is important in banking, hospital care, education, air travel, food industries, auto repair, postal delivery services and a host of other firms in the service industry.Quality management (QM) is the commonly used term for stressing quality within an organization. From the results, it was found that most of the process data collated and analyzed lies within the designed range of specifications, gives values implying that the process is capable of producing acceptable product. 2.2.2.

Copyright © 2020 Edu Electronic Books NIG. Conclusively,, the findings of this research shows that none of the points fell above or below the specification limits, and thus the process was in state of statistical control or simply in control. 6 The data was presented in a tabular form whereas the control chart for number of defects per unit (C- chart) and control chart for fraction of defectives (P-chart) was used to analyze the process. The Statistical process control (SPC) is the application of the same 14 tools to control process inputs (independent variables). Quality has become one of the most important consumer decision factors in the selection among competing products and services. However, those ones out of control which are attributed to assignable causes such as lack of personal training, poor mix, mechanical fault, etc, are to be subjected to process monitoring and evaluation so as to better their products.
