The forecast for any period equals the
previous period’s actual value.
It’s like driving a car by
looking in the rear-view

12. Importance of Forecasting
Provides relevant and reliable information
about the past and present events and the
likely future events. This is necessary for
sound planning.
It gives confidence to the managers for making
important decisions.
It is the basis for making planning premises.
It keeps managers active and alert to face
challenges of future events and the changes in
the environment.
13. Importance in different areas
Fore casting is important for:
Finance uses the long term forecasts to evaluate capital
investment needs.
Human Resources uses forecasts to evaluate personnel
needs.
IT designs and implements systems that generate
forecasts.
Marketing develops sales forecasts used for mid-term to
long term planning.
Operations develops and uses forecasts to make
decisions such as: scheduling, inventory management
and long term capacity planning.
14. The collection and analysis of data about the past, present and
future involves a lot of time and money. Therefore, managers have
to balance the cost of forecasting with its benefits. Many small firms
don’t do forecasting because of high cost.
Forecasting can only estimate the future events. It can guarantee
that these events will take place in the future. Long term forecasts
will be less accurate as compared to short term forecasts.
Forecasting is based on certain assumptions. If these assumptions
are wrong, the forecasting will be wrong. Forecasting is based on
past events. However, history may not repeat itself at all times.
Forecasting requires proper judgment and skills on the part of
managers. Forecasts may go wrong due to bad judgment and skills
on the part of some of the managers. Therefore, forecasts are
subject to human error.
15. Choosing a Forecasting TechniqueChoosing a Forecasting Technique
No single technique works in every situation
Two most important factors
Cost
Accuracy
Other factors include the availability of:
Historical data
Computers
Time needed to gather and analyze the data
Forecast horizon
16. Elements of a good forecastElements of a good forecast
1. Appropriate forecast horizon
2. Degree of accuracy should be taken into
account
3. Reliable
4. Choose meaningful units (dollars versus units)
5. Use same forecast throughout organization

Prévisions = Étape préalable à la planification Utilisées pour - Planifier le système d’opération (LT) - Planifier l’utilisation de ce même système (CT) Les clients n’attendront pas pour un bien de consommation ou pour un service. On doit anticiper les besoins des acheteurs potentiels.
