Planning is concerned with bridging the gap between where the organization is now and where it wants to be in the future. This involves two distinct processes measuring the current "state of play" of the organization and then predicting the future in a quantifiable way. The plan acts as a target to aim for and a yardstick for controlling operations - deviations from the plan give feedback signals for corrective action if necessary.
Techniques work with figures of some kind - accounting/financial ratios and statistical abstractions. Techniques are attempts to rationalize data as the sheer size and complexity of modern organization and their operations no longer allow managers to proceed by trial and error - this can so easily become trial and catastrophe. More advanced techniques, such as operational research and P.E.R.T. demand the building of models.
It is to be remembered that all techniques are aids and no matter how sophisticated the methods it is the manager himself who is ultimately has to make the decisions.
FORECASTING TECHNIQUES
Forecasts - usually for comparatively short periods of time of 6-12 months -
are extensively used by commerce and industry especially within the context of
sales forecasting and production planning/stock control.
By using statistical methods of smoothing out predictable fluctuations
(monthly seasonal, non recurring random variations), it is possible to predict
a future pattern to be compared with a trend line, which itself may be up or down
according to demand in the market place.
The trend is an extrapolation from past actual figures. As with any prediction,
the immediate future contains more certainties than the long distance future -
the daily weather forecast as compared with the long range forecast.
Long term planning (forecasts) are, however, increasingly used by large companies to cover any period from five to fifteen years, depending to a certain extent on the type of industry (the oil industry for example, works on very long term plans because of the length of time needed for exploration of oil-fields and the commissioning of refineries).
Budgets (plans, forecasts) are pre-determined statements of management policy during a given period which provides a standard for comparison with the results actually achieved.
