Quality Control

The quality control that Mens Wearhouse utilizes is the Quality Control Chart. This chart has a center line and lines above and below the center one. the center line is the average quality characterstic being measured. The line above is the upper control limit which represents the maximum acceptable random variation. The below line is the lower control limit which represents the minimum. If normal probability is assumed, these control limits will include 99.74% of random varations observed. Then attribute control is used using samples of 50-300. This uses a discrete scale rater than a continuous scale. With this, you consider the percentage of defectives occuring in a sample as the attribute measured. The percentage defective is estimated by taking a sample of units random at specific time intervals.

The six sigma quality approach is used. This process is usually applied to service and manufacturing comapnies. With this method, imporvements of merchandise and service are made using five steps.
1. Define: a process is chosen for improvements and a charter is specified.
2. Measure: quality is measured by customer tendencies and reactions. Goals are set for improvements.
3. Analyze: the reasons for the defects are indentified and alternatives are considered.
4. Improvements: the process is changed and double checked for improvements.
5. Control: this ensues that the prcess is not lost over time.

One improvement that can be made is instead of producing the items and then waiting to see customer reaction; whether it will sell or not, or whether the fitting is comfortable or not; they should test out the product on a small group to see their reactions instead of producing all of it and then fixing the problems.
