FRITO-LAY’S QUALITY-CONTROLLED
POTATO CHIPS
Note to instructors: Here is a real-world case of a company whose
products are known to every student. We suggest you show this
10-minute video in class as a basic tutorial on how to create an
SPC chart from scratch. The video walks students through the
factory and the statistical aspects of control charts.
1. The video shows how the UCL 2.22%
x  and LCL 1.98% x 
are developed for salt content of Lay’s chips. The population
standard deviation, from the video, is  = .07, which we will use
on the new data. The five sample means are 2.075, 2.015, 2.1375,
2.1, and 2.0975 for samples 1–5, respectively. X n   2.085. 4
   
   
UCL 2.085 3 .07 / 4 2.085 3 .035 2.19%
LCL 2.085 3 .07 / 4 2.085 3 .035 1.98%
x x
    
    
These new limits will be acceptable as they are even tighter than
the original delivery process for salt content.

2. Frito-Lay drivers deliver and stock supermarket shelves.
Advantages: (a) Control over shelf appearance—they always
straighten all bags/displays with every visit; (b) immediate sales
feedback; (c) awareness of competition; and (d) always in stock—
no lost sales.
Disadvantages: (a) Expensive and time-consuming for drivers to
act as store clerks.
LO S6.3: Build x-bar charts and R-charts
AACSB: Application of knowledge
3. Quality drives this consumer product. The taste of each chip
or other snack must be the same every bite. The bags must be
identical in weight and appearance. The product must be fresh.
Every step in production—from farm to factory—needs to meet
specifications. Quality is measured on dozens of measures and
monitored throughout the plant with SPC charts and computer
process controls.
