Final answer:
A manager opting not to conduct research due to the urgency of a decision exemplifies the influence of time constraints in marketing research. This situation necessitates immediate action based on existing data or intuitive judgment, often using cost/benefit analysis despite imperfect information.
Step-by-step explanation:
When a manager decides not to do research because a decision needs to be made before the results of the study can be analyzed, this is an example of time constraints in the determination of the need for marketing research. In a fast-paced business environment, managers often face situations where immediate decisions are required, and they have to act without the luxury of time that comprehensive research studies would entail.
For example, a marketing manager might need to quickly alter a marketing strategy based on a competitor's sudden campaign. Without time to conduct formal research, they could rely on existing data, past experiences, or even intuitive judgment to make an informed decision. The process of cost/benefit analysis, in particular, can play a significant role in these scenarios, helping to quickly weigh the potential risks and benefits without a detailed study. This approach recognizes the reality of imperfect information, as it's impossible to have all the data needed for a flawless decision. Thus, despite the constraints, managers still need to make the best decision possible with the information at hand.
