The final project is individual work.
Pick any national or international company with a product and/or service and do a report on it. Regardless of the project you use, you must answer the following SAMPLE questions (service vs. manufacturing)
For example, Dubai airport (service): what are the steps
· Give background on product/service/company
· Research the planning, coordination, communication, issues, etc. that occu
ed prior, during, and after this project.
· Provide your feedback with respect to the effectiveness, efficiency, productivity, and success/failure of this project.
· Identify any operations methods/concepts applied prior, during, and after the completion of this project.
· What have you learned while completing this assignment?
· Identify any methods and concepts you have learned that you can apply locally and personally.
Or, for example, the production of the Corvette Z06 (production); Chevrolet manufactures and sells a sports car called Corvette Z06. You are to complete the following:
· Give background on product/service/company

· Provide your feedback with respect to the effectiveness, efficiency, productivity, and success or failure of the operation.
· Provide your feedback on the operations methods/concepts applied in this production.
· What have you learned while completing this assignment?
· Identify any methods and concepts you have learned that you can apply locally and personally.

Forecast – a statement about the future value of a variable of interest
We make forecasts about such things as weather, demand, and resource availability
Forecasts are important to making informed decisions

Techniques assume some underlying causal system that existed in the past will persist into the future
Forecasts are not perfect
Forecasts for groups of items are more accurate than those for individual items
Forecast accuracy decreases as the forecasting horizon increases

Because random variation is always present, there will always be some residual e

Qualitative Forecasting
Qualitative techniques permit the inclusion of soft information such as:
Human factors
Personal opinions
Hunches
These factors are difficult, or impossible, to quantify
Quantitative Forecasting
These techniques rely on hard data
Quantitative techniques involve either the projection of historical data or the development of associative methods that attempt to use causal variables to make a forecast
Forecasting Approaches
LO 3.6
3-‹#›
13
Qualitative Forecasts
Forecasts that use subjective inputs such as opinions from consumer surveys, sales staff, managers, executives, and experts
Executive opinions
a small group of upper-level managers may meet and collectively develop a forecast
Sales force opinions
members of the sales or customer service staff can be good sources of information due to their direct contact with customers and may be aware of plans customers may be considering for the future
Consumer surveys
since consumers ultimately determine demand, it makes sense to solicit input from them
consumer surveys typically represent a sample of consumer opinions
Other approaches
managers may solicit 0pinions from other managers or staff people or outside experts to help with developing a forecast.
the Delphi method is an iterative process intended to achieve a consensus

Time-Series Forecasts
