Katanya Lyon operates the “Lyon King” hamburger stand at her local weekend market. She sells only two types of burgers: the MegaMeat burger with the works, and the PowerVeg burgers. Katanya employs the following family members:

• Sister Tankaya prepares bread rolls (including toasting and buttering). She gets cranky a lot because the toaster often overheats and the rolls get burnt and have to be thrown away;

• Brother Donnie, who is in charge of grilling (either meat patties or veggie patties; as well as grilling onion and frying eggs). Donnie only grills meat patties and veggie patties in different batches; he will never allow both meat patties and veggie patties to sit on the grill at the same time. Donnie believes that “mixed-grilling” is disrespectful to all the vegetarians out there. In contrast with Tankaya, Donnie is very relaxed, even when the grill breaks down (which happens twice a month on average).

• Mother Bonnie, who performs cutting and assembling activities (cutting lettuce and tomatoes, putting together the patties, eggs and the salad ingredients);

• Katanya looks after cash receipts herself.

  Katanya has a simple operation with only three major pieces of equipment: two toasters and one (very expensive) BeefEater Barbeque SL4000 Unit. Three suppliers provide all the main ingredients: the local butcher “Butch-a-Way” provides the meat patties and eggs, a vegetable supplier “All-Vegged-Out” supplies the salad ingredients; and “We-Bake” bakery supplies the bread rolls.

  Further, Katanya believes in specialisation; each employee focuses only on his/her own process. In particular, Katanya does not trust Donnie with the money, and she would never contemplate getting involved in the grilling process herself. In addition to cutting and assembling, Bonnie (who is good at haggling) is also in charge of negotiating deals with the suppliers. By purchasing in bulk she often manages to get large discounts.
