During the extended stage 6 loadshedding period

experienced at the beginning of 2023, many losses were experienced in the

poultry industry. Chickens could not be slaughtered when they reached the size

required by restaurants. Some slaughter facilities however used generators to

keep the slaughtering going, but that added an estimated 75c/kg on chicken

pieces. If the purchasing and supply manager of chicken for a restaurant chain purchases

from these slaughtering facilities with generators, what performance measure is

the most in jeopardy for the purchasing and supply department?
