Final answer:
Proponents of evidence-based management argue that there are few really new ideas in management, as many concepts and practices have already been studied and tested. They believe managers should rely on existing evidence and research to guide their decisions and actions.
Step-by-step explanation:
Evidence-based management is an approach that emphasizes using factual evidence and data to inform decision-making in management. Proponents of evidence-based management would argue that there are indeed few really new ideas in management. They believe that many concepts and practices in management have already been studied and tested, and that managers should rely on this existing body of knowledge to guide their decisions and actions. Instead of constantly seeking new ideas, evidence-based management encourages managers to apply proven practices and strategies that have been supported by robust evidence and research.
For example, in the field of organizational behavior, concepts such as motivation, leadership, and team dynamics have been extensively studied and there is a wealth of evidence about what works and what doesn't. Evidence-based management would suggest that managers should rely on this existing evidence to inform their decisions, rather than constantly searching for new ideas.
