Willemain was interested in determining the issues to which expert modellers devote attention as they formulate their models. He identified five topics important to modellers: . Problem context Model structure Model realization Model assessment Model implementation - Imagine a BUSINESS CASE, describe it, and explain each of these topics in your case. (5 points for each topic) This is an example response: I imagine a startup that wants to enter a new target market. Problem context: A startup wants to enter a new target market. They like to predict the number of customers in this new market. Model structure: They creates the assumptions such as: The product is innovative; The market is very small; we don't have direct access to the market; There is a limited budget marketing Model realization: The startup collects data by doing a quick survey and analyze the results. This survey will help them to have a sense of the new target market. Model assessment: They do a deeper assessment by doing a market research. They collect more data and evaluate their assumptions. Model implementation: Finally they work directly with an agent to ship the product to the new market and evaluate the market performance metrics. Paragraph V B I UA v bol P +
