Final answer:
All listed methods, including on-the-job training, online courses, seminars and workshops, and hiring external consultants, are acceptable for training food service personnel. Effectiveness depends on various factors and aligns with the specific needs and resources of the food service operation.
Step-by-step explanation:
All of the methods listed are generally accepted ways of training food service personnel on management practices, so the question might be based on a mistaken premise that one of them is not acceptable. Training efficacy can depend on various factors, including the immediate response of the employee to the training (1), testing at the end of training to demonstrate learning outcomes (2), behavioral measurements of job activities by supervisors (3), and results such as productivity and profits (4), as indicated by a study from Arthur, Bennett, Edens, and Bell in 2003. Different types of training, like self-instruction, lecture and discussion, and computer assisted training, might be more or less effective depending on these factors.
When determining the most effective training method, one should consider the specific needs and circumstances of the food service personnel, their learning styles, and the resources available for training. For example, on-the-job training can be highly effective for practical, hands-on learning experiences, while online courses provide flexibility and can cover a breadth of topics. Seminars and workshops offer interactive environments that can encourage engagement and networking, and hiring external consultants can bring in specialized knowledge and an outside perspective that might be lacking internally.
Additionally, when considering economic decisions, such as the example of a consultant who earns a significant hourly wage, it may make more economic sense for her to focus on her higher-earning consulting job and purchase vegetables rather than growing them, due to the concept of opportunity cost. This consultant would likely earn more by working for an additional hour than what she would save by growing her own vegetables, hence shopping for vegetables is a more efficient use of her time and expertise.
