Consumers make complaint about the state of home-made goods. Some of the consumers claim that foreign goods are of high quality compared to home-made goods. We discovered that many indigenous industries are no more in existence and so this brought the desire to carry out this research work so as to find out whether Life Lager beer, the product of an indigenous company is void of the consumers’ complaint. For clarity and easy handling of this topic, data were collected on the two major components that are used in the production of Life Lager Beer; Hop extract and Calcium hydroxide. The data collected covered a period of four months, from January to April and the readings were twice a day. This was collected from the company’s register. Control charts, Standard Deviation charts and Cumulative Sum Technique charts (CUSUM) were used in the analysis. The results were presented with the use of charts. The results indicated that Life Lager beer production materials are in perfect control.
