2019 BBA 315 – BUSINESS FORECASTING
Case Study Report 1
Due: 11 pm, Friday 3rd May
Format
The main tables, charts and results should be presented throughout the report to highlight your responses to the questions. All other computer output should be put into labelled and referenced appendices.
This Case Study Report assessment will require a written submission based around a comprehensive business forecasting project. You will need to determine and find suitable empirical data which will be then be used as the basis of relevant business forecasts and associated recommendations.
Reports are required to be submitted through Turn-it-in by the relevant date and time indicated above. Convert your DOC file into a PDF prior to submission. You will also have to upload your XLS file through iLearn. No extensions will be granted.
There will be a deduction of 10% of the total available marks made from the total awarded mark for each 24-hour period, or part thereof, that the submission is late (for example, 25 hours late in submission – 20% penalty). This penalty does not apply for cases in which an application for Special Consideration is made and approved.
The task involves choosing appropriate data for the task. The choice of appropriate data needs to be justified and relevant data selection is part of the assessment process.
Forecasts for the relevant target variable will be related to forecasts for variables available through the ABS website. Often in forecasting and other research, the available data will not perfectly match the situation. The forecaster/researcher needs to make a judgment on suitable data that approximate the exact variable (s) needed.
The only thing you should do is to type your answers directly on the file, including cutting and pasting relevant output from EXCEL or MINITAB.

2019 BBA 315 – BUSINESS FORECASTINGCase Study Report 1
Due: 11 pm, Friday 3rd May
Each student has been assigned an airline as per the ‘Airline’ list in the Assignment section on iLearn.
You are working for your designated airline and the board of your airline is considering the launch of new direct flight services to Australia (Sydney / Melbourne / Perth) from your home country and/or a codeshare service via a flight to Australia (Sydney / Melbourne / Perth) through an international hub where your airline already services – either Dubai or Singapore. In this regard, you need to forecast the visitor numbers from the country of origin of your airline into Australia for at least the upcoming year. You will need accurate forecasts for each month of the year as you need to adjust your airline’s schedule depending on the differential demand in each month.
Questions
- Identify a relevant time series for the visitors arriving to Australia from your airline’s home country (for at least the last 20 years) which may be useful in generating the forecasts required by your airline. You may merge time series if you deem this is necessary. Justify your choice/s.
Data should be available through the Australian Bureau of Statistics (ABS).
Provide a line chart of the relevant time series for approximately the last 20 years.
- Comment in general on the characteristics of the time series line chart. What systematic components are evident in the time series? Explain your answer.
- Confirm the presence of the systematic components of the time series using relevant tools and measures. Explain your answer.
- Outline the economic and environmental factors or circumstances which are likely to have influenced the characteristics or components of the time series. Will these factors or circumstances apply to the relevant forecasting period? Explain your answer.
- Without applying a decomposition, apply an appropriate method in EXCEL to smooth (remove randomness) the chosen time series for the last 4 years to help further identify the relevant systematic components. Explain what you have done.
- From the results of the above smoothing, provide a time series line chart comparing the original time series with the generated smoothed values. Comment on your smoothing. Include the forecasts from #10 as part of your line chart above.
- Perform the appropriate tests for whether your model has captured all the systematic components and/or whether the errors are random. Explain your answer.
- Do the results in #6 and #7 suggest any re-evaluation or modification, if at all? Explain your answer.
- Using the results of the smoothing method you applied, provide numerical estimates for the underlying systematic components (for example, if a trend is observed provide a relevant trend equation and/or if seasonality is observed provide estimates of the seasonal relatives or indexes).
Using your results, provide an appropriate time series model for the time series you selected in #1.
Critically evaluate your choice of model.
- Use EXCEL to provide relevant monthly forecasts for total visitor arrivals from your airline’s home country to Australia for each month beyond the sample data period (one year of monthly out-of-sample forecasts). Compare and contrast your forecasts using MINITAB. Comment on any differences you observe between the two sets of forecasts.
Explain why (or why not) such a time frame (one year of monthly out-of-sample forecasts) beyond the sample period would be appropriate for the launch of new air travel routes.
Critically evaluate the factors you would need to consider when forecasting for the second or third year (of monthly forecasts) beyond the sample period.
