11. Forecasting
Predicting the future
Qualitative forecast methods
– subjective
Quantitative forecast methods
– based on mathematical formulas
Depend on
– time frame
– demand behavior
– causes of behavior
12. Demand Forecasting
Qualitative Methods
– These methods rely essentially on the judgment
of experts to translate qualitative information into
quantitative estimates
– Used to generate forecasts if historical data are
not available (e.g., introduction of new product)
– The important qualitative methods are:
• Jury of Executive Method
• Delphi Method
12
13. Jury of Executive Opinion Method
Rationale
– Upper-level management has best information on latest
product developments and future product launches
Approach
– Small group of upper-level managers collectively develop
forecasts – Opinion of Group
Main advantages
– Combine knowledge and expertise from various
functional areas
– People who have best information on future
developments generate the forecasts
13
14. Jury of Executive Opinion Method
Main drawbacks
– Expensive
– No individual responsibility for forecast quality
– Risk that few people dominate the group
– Subjective
– Reliability is questionable
Typical applications
– Short-term and medium-term demand forecasting
14
15. Delphi Method
Rationale
– Eliciting the opinions of a group of experts with
the help of mail survey
– Anonymous written responses encourage honesty
and avoid that a group of experts are dominated by
only a few members
15
17. Delphi Method
Main advantages
– Generate consensus
– Can forecast long-term trend without availability of
historical data
Main drawbacks
– Slow process
– Experts are not accountable for their responses
– Little evidence that reliable long-term forecasts can be
generated with Delphi or other methods
Typical application
– Long-term forecasting
– Technology forecasting
17
18. Time Series Projection Methods
• These methods generate forecasts on the basis of an
analysis of the historical time series.
• Assume that what has occurred in the past will
continue to occur in the future
• Relate the forecast to only one factor - time
The important time series projection methods are:
– Trend Projection Method
– Exponential Smoothing Method
– Moving Average Method
18
19. Trend Projection Method
Advantages
• It uses all observations
• The straight line is derived by statistical procedure
• A measure of goodness fit is available
Disadvantages
• More complicated
• The results are valid only when certain conditions are
satisfied
19
20. Exponential Smoothing
Exponential smoothing, forecasts are modified in the
light of observed errors.
If the forecast value for year t, Ft, is less than the
actual value for year t, St, the forecast for the year
t+1, Ft + 1 ..
Ft + 1 = Ft + α et
Where Ft + 1 = forecast for year )
α = smoothing parameter
et = error in the forecast for year t = St = Ft
22. Moving Average
Naive forecast
– demand in current period is used as next period’s forecast
Simple moving average
– uses average demand for a fixed sequence of periods
– stable demand with no pronounced behavioral patterns
Weighted moving average
– weights are assigned to most recent data
According to the moving average method
St + S t – 1 +…+ S t – n +1
Ft + 1 =
n
where Ft + 1 = forecast for the next period
St = sales for the current period
n = period over which averaging is done

25. Causal Methods
Causal methods seek to develop forecasts on
the basis of cause-effects relationships
specified in an explicit, quantitative manner.
– Chain Ratio Method
– Consumption Level Method
– End Use Method
– Leading Indicator Method
– Econometric Method
25
26. Chain Ratio Methods
Market Potential for heated coats in the U.S.:
– Population (U) = 280,000,000
– Proportion of U that are age over 16 (A) = 75%
– Proportion of A that are men (M) = 50%
– Proportion of M that have incomes over $65k (I) = 50%
– Proportion of I that live in cold states (C) = 50%
– Proportion of C that ski regularly (S) = 10%
– Proportion of S that are fashion conscious (F) = 30%
– Proportion of F that are early adopters (E) = 10%
– Average number of ski coats purchased per year (Y) = .5
coats
– Average price per coat (P) = $ 200
26
27. Chain Ratio Methods
Market Potential for heated coats in the U.S.:
Market Sales Potential =
UxAxM xI xCxS xF xExY
= 280 Million x 0.75 x 0.50 x 0.50 x 0.50 x 0.10 x
0.30 x 0.10 x200
= $7.88 Million
27
28. Consumption Level Method
This method is used for those products that are
directly consumed. This method measures the
consumption level on the basis of elasticity
coefficients.
28
29. Consumption Level Method
Income Elasticity: This reflects the responsiveness
of demand to variations in income. It is calculated
as:
E1 = [Q2 - Q1/ I2- I1] * [I1+I2/ Q2 +Q1]
• Where
E1 = Income elasticity of demand
Q1 = quantity demanded in the base year
Q2 = quantity demanded in the following year
I1 = income level in the base year
I2 = income level in the following year
29
30. Consumption Level Method
Price Elasticity: This reflects the responsiveness of
demand to variations in price. It is calculated as:
EP = [Q2 - Q1/ P2- P1] * [P1+P2/ Q2 +Q1]
• Where
EP = Price elasticity of demand
Q1 = quantity demanded in the base year
Q2 = quantity demanded in the following year
P1 = price level in the base year
P2 = price level in the following year
30
31. End Use Method
Suitable for estimating demand for intermediate
products
Also called as consumption coefficient method
Steps
1. Identify the possible uses of the products
2. Define the consumption coefficient of the product
for various uses
3. Project the output levels for the consuming
industries
4. Derive the demand for the project
31
32. End Use Method
This method forecasts the demand based on the
consumption coefficient of the various uses of the
product.
Projected Demand for Indchem
Consumption Projected Output Projected Demand for
Coefficient in Year X Indchem in Year X
Alpha 2.0 10,000 20,000
Beta 1.2 15,000 18,000
Kappa 0.8 20,000 16,000
Gamma 0.5 30,000 15,000
Total 69,000
32
33. Leading Indicator Method
This method uses the changes in the leading
indicators to predict the changes in the
lagging indicators.
Two basic steps:
1. Identify the appropriate leading indicator(s)
2. Establish the relationship between the leading
indicator(s) and the variable to forecast.
33
34. Econometric Method
An advanced forecasting tool, it is a mathematical
expression of economic relationships derived from
economic theory.
Economic variables incorporated in the model
1. Single Equation Model
Dt = a0 + a1 Pt + a2 Nt
Where
Dt = demand for a certain product in year t.
Pt = price of the product in year t.
Nt = income in year t.
34
35. Econometric Method
2. Simultaneous equation method
GNPt = Gt + It + Ct
It = a0 + a1 GNPt
Ct = b0 + b1 GNPt
• Where
GNPt = gross national product for year t.
Gt = Governmental purchase for year t.
It = Gross investment for year t.
Ct= Consumption for year t.
35
36. Econometric Method
Advantages
• The process sharpens the understanding of
complex cause – effect relationships
• This method provides basis for testing
assumptions
Disadvantages
• It is expensive and data demanding
• To forecast the behaviour of dependant
variable, one needs the projected values of
independent variables
36
37. Uncertainties in Demand Forecasting
Data about past and present markets.
– Lack of standardization:- product, price, quantity,
cost, income….
– Few observations
– Influence of abnormal factors:- war, natural
calamity
Methods of forecasting
– Inability to handle unquantifiable factors
– Unrealistic assumptions
– Excessive data requirement 37
38. Uncertainties in Demand Forecasting
Environmental changes
– Technological changes
– Shift in government policy
– Developments on the international scene
– Discovery of new source of raw material
– Vagaries of monsoon
38
39. Coping With Uncertainties
Conduct analysis with data based on uniform
and standard definitions.
Ignore the abnormal or out-of-ordinary
observations.
Critically evaluate the assumptions
Adjust the projections.
Monitor the environment.
Consider likely alternative scenarios.
Conduct sensitivity analysis
