QUESTION 6 Farah Rashid has just returned from a study abroad where she learned about trade-offs between various dimensions of operations performance. Her brother Hammad says that what she has learned is typical ivory tower useless theory, because he was able to improve the cost efficiency, flexibility and quality of his production process at the same time. Hammad achieved that by investing in new production technologies. What is the best explanation of the contradiction between Farah's textbook and what her brother achieved? There are always strict trade-offs, so the only explanation is that there is a lot of measurement error and Hammad didn't measure the performance properly. OB. Farah learned theory about trade-offs, and reality is different. Theory doesn't apply in real life. OC. There are no trade-offs, Farah's textbook was too old (outdated) Hammad's production was below the efficiency frontier, so he was able to invest in new technology to OD simultaneously improve on various dimensions. Trade-offs happen once on the efficiency frontier.
