MSIS 3223 Exam #2/80 Q/A
True - -Correlation measures the strength and direction of a relationship
between variables
- True - -The Delphi approach involves the use of a series of questionnaires
to achieve a consensus forecast
- True - -In order to update a moving average forecast, the value of each
data point in the average must be known
- False - -Forecasts based on time-series (historical) data are referred to as
associative forecasts
- True - -The best forecast is not necessarily the most accurate
- False - -MAD is equal to the square root of MSE, which is why we calculate
the easier MSE and then calculate the more difficult MAD
- True - -Organizations that are capable of responding quickly to changing
requirements can use a shorter forecast horizon and therefore benefit from
more accurate forecasts
- True - -An advantage of trend-adjusted exponential smoothing over the
linear trend equation is its ability to adjust over time to changes in the trend
- True - -Trend-adjusted exponential smoothing requires selection of two
smoothing constants
- True - -An advantage of a weighted moving average is that recent actual
results can be given more importance than what occurred a while ago.
- Time series analysis - -Which of the following is not a type of judgmental
forecasting?
- Members of the sales force can have difficulty distinguishing between what
customers would like to do and what they actually will do. - -Which of the
following is a potential shortcoming of using sales force opinions in demand
forecasting?
- Demand forecasts - -Which of the following is/are a primary input into
capacity, sales, and production planning?
- Smooth variations in the data - -Moving average forecasting techniques do
the following:
, - MAPE - -Putting forecast errors into perspective is best done using
- Second opinions - -Forecasts based on judgment and opinion do not
include:
- True - -Reliability can be improved by the use of backup components.
- False - -To save money, it is essential that designers revise the production
capabilities to meet the requirements of the new products.
- False - -Robust design describes a product that will perform satisfactorily
so long as it is used in a very narrow range of conditions.
- True - -A service blueprint is quite similar to an architectural drawing.
- False - -A house of quality is achieved when no department in a single
location has more than 15 percent rejects.
- True - -Applied research is the major R&D effort of business organizations
because of their desire for commercial applications.
- False - -Taguchi design methods involve identifying the optimal operating
or environmental conditions for a given product.
- True - -Reliability can be defined in terms of a particular point in time or in
terms of length of service.
- True - -The demand for a product and the rate of technological change
have a significant impact on the length of a given phase of the product life
cycle.
- True - -Product liability means that a manufacturer is liable for any injuries
or damages caused by a faulty product because of poor workmanship or
design.
- False - -The term failure as applied to reliability means that a part or item
does not function at all.
- True - -Applied research has the objective of achieving commercial
applications for new ideas.
- False - -The process of dismantling and inspecting a competitor's product
to discover product improvement is called benchmarking.
