QUALITY CONTROL MANAGEMENT 1

Summary

Quality control is a procedure or set of procedures intended to ensure that a manufactured product or performed service adheres to a defined set of quality criteria or meets the requirements of the client or customer. It might include whatever actions a business deems necessary to provide for the control and verification of certain characteristics of a product or service. Most often, it involves thoroughly examining and testing the quality of products or the results of services. The basic goal of this process is to ensure that the products or services that are provided meet specific requirements and characteristics, such as being dependable, satisfactory, safe and fiscally sound. In this individual project, MIRAS bottling company's quality control will be determined according to given data.

Problem Description

Bottling facility periodically tests its bottling function under quality control department. To study and control manufacturing process 60 samples with 3 observations total 180 bottled products were chosen from different shifts over several days of operation. Products were measured that from bottled limit to cap in millimeters. Expected result is operating is in control.

In order to decide if operating in control or not, I will create control charts with given data.

Methods

I used X charts and R charts in order to measure quality control of output. Output of the process is measured in length. Argument is if bottles were bottled with enough drink. Measured length is between bottled limit and cap of bottle in millimeter. Since defective items were not given I did not use p chart and np chart for quality control. Standard was set as 3.4 millimeter.
