3. Introduction
Targets:
Most of the companies working
on achieving goals, targets, and
evaluate their achievements by
comparing the current achieved
results to results of previous
week, month, or year i.e looking
backward to analysis current
situation.

4. Introduction
But for setting targets we have
to look forward, forecast,
develop a plan for current
situation, to achieved these
targets in future in most efficient
way, so we can compare the
current achievement by the
target one, here we can measure
our performance & KPI.

6. Forecasting –Trend vs Seasonal
Trend Forecasting
Tell us in which direction (Growth) of
the historical data, and usually is a
long term forecast.
Seasonal Forecasting
Tell us the Seasonal, Cyclic shocks,
we used it to define the forecasting
Pattern
Trend vs Seasonal Forecasting
Forecasted Year of TREND
= Sum of 12 forecasted Seasonal
Months for same year,

7. Model Fairness
Two Main factors:
Evaluation Forecasting
R2 = Coef. Of Determination T. S. = Tracking Signal

8. Model Fairness
Two Main factors:
R2 > 80%
AND
-4 < T.S.< 4
R2 = Coef. Of Determination T. S. = Tracking Signal

20. Summary
Most of the companies practice the classical methods, they
evaluate their current performance based on the past results, they
just only looking to the back only for one Year ( or same period as
month).
While this study explore the effect of historical data in
terms of trends forecast, in which direction the company business
moves, and the second part is addressing the short term impacts of
seasonality (here months) based on three (3) years monthly data
base, keeping in mind the model fairness constrains i.e (R 2) and
(T.S.) to minimise the forecasting errors, then compare the
forecasted/planned figures by the actual one.
The new constrain for this model is to match the accumulated forecasted
months by (Seasonal Model – 3 year data base) with the proposed forecasted year of
Trend analysis (Trend Model – 19 years data base).
Results:
By Planning method the accuracy is high in terms of Standard Deviation i.e 0.037
and Classical method is 0.092.
