Destination Title: Kentucky Fried Chicken



1. Describe Kentucky Fried Chicken's business niche. What type of business organization is it?

KFC Corporation, based in Louisville, Kentucky, is the world's most popular chicken restaurant chain, specializing in Original Recipe®, Extra Crispy®, Kentucky Grilled Chicken™ and Original Recipe Strips with home-style sides, Honey BBQ Wings, and freshly made chicken sandwiches.

Every day, more than 12 million customers are served at KFC restaurants in 109 countries and territories around the world. KFC operates more than 5,200 restaurants in the United States and more than 15,000 units around the world. KFC is world famous for its Original Recipe® fried chicken -- made with the same secret blend of 11 herbs and spices Colonel Harland Sanders perfected more than a half-century ago. Customers around the globe also enjoy more than 300 other products -- from Kentucky Grilled Chicken in the United States to a salmon sandwich in Japan.

KFC is part of Yum! Brands, Inc., the world's largest restaurant company in terms of system restaurants, with more than 36,000 locations around the world. The company is ranked #239 on the Fortune 500 List, with revenues in excess of $11 billion in 2008.

2. How did Colonel Sanders start KFC, and why?


In the midst of the depression, Harland Sanders opens his first restaurant in the small front room of a gas station in Corbin, Kentucky. Sanders serves as station operator, chief cook and cashier and names the dining area "Sanders Court & Café."

3. What product, facility, retail sales, and employee information is provided?



Facility, store locations can be searched; a SHOP page is available, sales info is available in the "About Us" section; "Careers" describes the work at KFC.

4. Select the "Animal Welfare" page on the left of your computer screen. What has KFC done to ensure animal welfare?


We are monitoring our suppliers on an ongoing basis to determine whether our suppliers are using humane procedures for caring for and handling animals they supply to us. KFC formed the Animal Welfare Advisory Council, which consists of highly regarded experts in the field. We were also a prominent player in the joint effort conducted by the National Council of Chain Restaurants and the Food Marketing Institute to develop comprehensive guidelines for all species of farm animals. KFC has implemented a farm level audit program - a program which is industry-leading in the areas of poultry care and handling.

Why is Animal Welfare an issue for the Colonel?

Animal slaughter for KFC is halal (done in accordance to Islamic law) compliant in some areas. Non-Muslims have objected to the allegedly cruel nature of Islamic animal treatment as well as groups such as PETA (People for the Ethical Treatment of Animals) have raised concerns about Islamic practices.

The Halal Food Authority in England endorses KFC animal slaughtering.


The imposition of halal includes many British supermarkets, fast-food chains, hospitals, schools, pubs and sporting arenas such as Wembley Stadium, serving halal meat and poultry without notifying the public; the American Muslim Consumer Conference started to follow suit in the U.S. (as of Dec. 2010) and attracted 400 attendees.

Section 2 The Theory of Production, p. 127

The theory of production deals with the way output changes in the short run when a single productive input is varied. This relationship is presented graphically in the form of a production function. The two most important measures of output are total product and marginal product. Three stages of production—increasing returns, diminishing returns, and negative returns—show how marginal product changes as additional variable inputs are added.

Chapter 5, Section 2 - Reading Strategy

In-class assignment (you may work with a partner for the exercise):

Directions: Listing

As you read about production, complete the graphic organizer by listing what occurs during the three stages of production.

Chapter 5, Section 2 - Review

In-class assignment (you may work with a partner):

Directions: Explaining

Complete the graphic organizer by explaining how marginal product changes in each of the three stages of production.

Section 3: Cost, Revenue, and Profit Maximization

Cost and revenue are added to the theory of production. Several important measures of cost are introduced, including fixed cost, variable cost, total cost, and marginal cost. Total revenue and marginal revenue are the most important measures of revenue. The firm reaches the break-even point when the revenue from sales is large enough to cover the total cost of production. Furthermore, the firm finds its profit-maximizing quantity of output where the marginal cost of production is exactly equal to marginal revenue from the sale of the product.
