Forecasting techniques generally assume an existing causal system that will continue to exist in the future

For new products in a strong growth mode, a low alpha will minimize forecast errors when using exponential smoothing techniques

Once accepted by managers, forecasts should be held firm regardless of new input since many plans have been made using the original forecast

Forecasts for groups of items tend to be less accurate than forecasts for individual items because forecasts for individual items don't include as many influencing factors

Forecasts help managers both to plan the system itself and to provide valuable information for using the system

Organizations that are capable of responding quickly to changing requirements can use a shorter forecast horizon and therefore benefit from more accurate forecasts

When new products or services are introduced, focus forecasting models are an attractive option

The purpose of the forecast should be established first so that the level of detail, amount of resources, and accuracy level can be understood

Forecasts based on time-series (historical) data are referred to as associative forecasts

Time-series techniques involve the identification of explanatory variables that can be used to predict future demand

A consumer survey is an easy and sure way to obtain accurate input from future customers since most people enjoy participating in surveys

The Delphi approach involves the use of a series of questionnaires to achieve a consensus forecast

Exponential smoothing adds a percentage (called alpha) of the last period's forecast to estimate the next period's demand

The shorter the forecast period, the more accurately the forecasts tend to track what actually happens

Forecasting techniques that are based on time-series data assume that future values of the series will duplicate past values

Trend-adjusted exponential smoothing uses double smoothing to add twice the forecast error to last period's actual demand

Forecasts based on an average tend to exhibit less variability than the original data

The naive approach to forecasting requires a linear trend line

The naive forecast is limited in its application to series that reflect no trend or seasonality

The naive forecast can serve as a quick and easy standard of comparison against which to judge the cost and accuracy of other techniques

A moving average forecast tends to be more responsive to changes in the data series when more data points are included in the average

In order to update a moving average forecast, the values of each data point in the average must be known

Forecasts of future demand are used by operations people to plan capacity

An advantage of a weighted moving average is that recent actual results can be given more importance than what occurred a while ago

Exponential smoothing is a form of weighted averaging

A smoothing constant of .1 will cause an exponential smoothing forecast to react more quickly to a sudden change than a smoothing constant value of .3

The T in the model TAF = S + T represents the time dimension (which is usually expressed in weeks or months). 

Trend-adjusted exponential smoothing requires selection of two smoothing constants

An advantage of trend-adjusted exponential smoothing over the linear trend equation is its ability to adjust over time to changes in the trend

A seasonal relative (or seasonal indexes) is expressed as a percentage of average or trend

In order to compute seasonal relatives, the trend of past data must be computed or known, which means that for brand-new products this approach cannot be used

Removing the seasonal component from a data series (deseasonalizing) can be accomplished by dividing each data point by its appropriate seasonal relative

If a pattern appears when a dependent variable is plotted against time, one should use time series analysis instead of regression analysis

Curvilinear and multiple regression procedures permit us to extend associative models to relationships that are nonlinear or involve more than one predictor variable

The sample standard deviation of forecast error is equal to the square root of MSE

Correlation measures the strength and direction of a relationship between variables

MAD is equal to the square root of MSE, which is why we calculate the easier MSE and then calculate the more difficult MAD

In exponential smoothing, an alpha of 1.0 will generate the same forecast that a naive forecast would yield

A forecast method is generally deemed to perform adequately when the errors exhibit an identifiable pattern

A control chart involves setting action limits for cumulative forecast error

A tracking signal focuses on the ratio of cumulative forecast error to the corresponding value of MAD. 

The use of a control chart assumes that errors are normally distributed about a mean of zero

Bias exists when forecasts tend to be greater or less than the actual values of time series. 

Bias is measured by the cumulative sum of forecast errors

Seasonal relatives can be used to deseasonalize data or incorporate seasonality in a forecast

The best forecast is not necessarily the most accurate

Which of the following is a potential shortcoming of using sales force opinions in demand forecasting? 

Suppose a four-period weighted average is being used to forecast demand. Weights for the periods are as follows: w_t-4 = 0.1, w_t-3 = 0.2, w_t-2 = 0.3 and w_t-1 = 0.4. Demand observed in the previous four periods was as follows: A_t-4 = 380, A_t-3 = 410, A_t-2 = 390, A_t-1 = 400. What will be the demand forecast for period t

Suppose a three-period weighted average is being used to forecast demand. Weights for the periods are as follows: w_t-3 = 0.2, w_t-2 = 0.3 and w_t-1 = 0.5. Demand observed in the previous three periods was as follows: A_t-3 = 2,200, A_t-2 = 1,950, A_t-1 = 2,050. What will be the demand forecast for period t?

Global teams provide diversity while eliminating conflicts and miscommunication

A ‘House of Quality' is achieved when no department in a single location has more than 15% rejects

Concurrent Engineering is another term for sequential development

One of the main advantages of standardization is that it increases the potential variety of products

A disadvantage of standardization is the possibility of standardizing designs too early, which may make it difficult to modify in the future

Reducing consumer choices makes service more efficient

Modular design increases costs of purchasing and controlling inventory compared to non-modular

Product failures can be easier to remedy with modular design

One motivation for an organization to redesign its product or service is to avoid the alternative of downsizing the organization

A major benefit of Computer Aided Design (CAD) is the increased productivity of designers

Most of the time what is called product or service design is actually a redesign of an existing product or service

A service blueprint is quite similar to an architectural drawing

The process of dismantling and inspecting a competitor's product to discover product improvement is called benchmarking

To save money, it is essential that designers revise the production capabilities to meet the requirements of the new products

Many US manufacturers are now shifting their focus from products to both product and process improvements

Applied research has the objective of achieving commercial applications for new ideas

Basic research is done with the expectation that discoveries will have near-term commercial application

"Design for production" takes into account the capabilities of the organization to produce or deliver a given product or service

Consumers tend to resist purchasing products containing recycled materials

"Concurrent engineering" brings people concerned with manufacturing into the design phase earlier than in the "over-the-wall" approach

"Concurrent engineering" means that at least two engineers are involved in product design at the same time

One approach to extending a product's life cycle is to promote alternate uses of the product

"Quality Function Deployment" is a structured approach that guarantees that the highest quality product or service will be designed

Product liability means that a manufacturer is liable for any injuries and damages caused by a faulty product because of poor workmanship or design

The process of dismantling and inspecting a competitor's product to discover improvement is called reverse engineering

Research and development (R&D) refers to organized efforts that are directed toward increasing scientific knowledge and product (or process) innovation

Standardization refers to the extent to which there is absence of variety in a product, service, or process

Re-manufacturing refers to removing some of the components of old products and reusing them in new products

The demand for a product and the rate of technological change have significant impact on the length of a given phase of the product life cycle

Robust design describes a product that will perform satisfactorily so long as it is used in a very narrow range of conditions

Taguchi design methods involve identifying the optimal operating or environmental conditions for a given product

Quality function deployment (QFD) is based on a set of standards which relate customer requirements to company capabilities.

The quality function deployment (QFD) matrices are often referred to as the "House of Quality" because, when completed, they "house" all of the customer's quality requirements

Service design often must take into account the degree of customer contact required

Reliability refers to the ability of a product to perform its intended function under normal conditions

Applied research is the major R & D effort of business organizations because of the desire for commercial applications

Commonality of components is beneficial for manufacturing but not for services

Standardization can at times lead to serious difficulties and competitive struggles, particularly when systems are running under different conditions

The term failure as applied to reliability means that a part or item does not function at all

Reliability can be defined in terms of a particular point in time or in terms of length of service

Reliability can be improved by the use of backup components

Delayed differentiation and modular design are tactics for mass customization

Life-cycle assessment involves incorporating where the product or service is in its life-cycle into system-design decision-making

The goal of life-cycle assessment is to incorporate the environmental impact of products or services into product-design or service-design decision-making
