Forecasting (Scenario)
Imagine that you are a manager in the construction industry in Calgary, Alberta.

The provincial government has been easing restrictions on public land use and has promoted a business-friendly environment to attract more corporations to the area. Furthermore, the oil business is booming, and there is a severe shortage of housing and worker accommodations in the oil-producing regions. However, you are also aware of how quickly these factors can change and the impact that a change in government or a decline in the price of oil can have on the construction industry. Given these considerations, you try to develop a forecast to help plan your company's future.
