Advantages of Forecasting

1] Assists in Planning

One of the biggest advantages of forecasting is that it enables the manager to plan for the future of the organization. Planning and forecasting actually go hand in hand. Without an idea of what the future hols for the company, we cannot plan for it. Thus, forecasting plays a very important role in planning.

2] Environmental Changes

When done correctly, forecasts should be able to point out the upcoming changes in the environment. This means that it can allow the company to benefit from such environmental changes. When the changes are favorable to the company it can expand and grow its business. And in conditions that are adverse, it can plan and prepare to protect itself.

3] Identifying Weak Spots

Another advantage of forecasting is that it will help the manager identify any weak spots, or ignored areas that the organization may have. Once attention has been drawn to these areas, the manager can put into effect effective controls and planning techniques to rectify them.

4] Improves Co-ordination and Control

Forecasting requires information and data from a lot of external and internal sources. This information is collected by the various managers and staff from various internal sources. So almost all units and verticals of the organization are involved in the process of forecasting. This allows for better communication and coordination amongst them.

Limitations of Forecasting

Along with the benefits, there are also some limitations of forecasting. Let us take a look at a few of them,

1] Just Estimates

The future will always be uncertain. Even if use the best of forecasting techniques and account for every aspect imaginable, a forecast is still just an estimate. One can never predict future events with 100% success. So even the best-laid plans may amount to nothing. This will always remain one of the biggest limitations of forecasting.

2] Based on Assumptions

The basis of any forecasting method is assumptions, approximations, normal conditions, etc. This makes these forecasts unreliable. So one must always keep in mind the inherent limitations of forecasting and be cautious in being over-reliant on them.

3] Time and Cost Factors

The data and information required to make formal forecasts are generally a lot. And the collection and tabulation of such data involve a lot of time and money. The conversion of qualitative data into quantitative data is also another factor. One must be careful that the time, money and effort spent forecasting must not outweigh the actual benefits from such forecasts.
