Enhanced Production Management - By far one of the biggest perks of utilizing accurate forecasting the just-in-time method of inventory management schedules production near expected sales or delivery needs to reduce inventory carrying costs.

Accurate sales and demand forecasting enables you to spread out production to ensure your customers and clients have products when they need it. Sales also differ from demand in the regard that some of your customers, usually retailers, may need to stock their shelves or fill a warehouse before items start selling. Adequately forecasting a product enables you to better plan your production needs.

Since forecasts attempt to look into the future, certain assumptions need to be made that form the basis of the forecast. Businesses need to take the following into account:. From here, businesses need to decide on the segmentation for their forecast; i. Businesses then need to determine which forecasting method is appropriate. There are three general methods:.

Qualitative approaches are generally used when data is not readily available —in instances when a business, product or service is new. Typically this technique uses expert opinions and informed judgements that are logical, systematic, and unbiased in their estimations, which are then quantified. As the name implies, they are not as rigorous generally as quantitative methods.

New businesses or businesses with new products might not be able to use this method. The forecast is extrapolated by recognizing patterns, trends, and changes in the data using this mathematical technique.

Causal modeling , the most sophisticated of the three forecasting tools, identifies the relevant causal relationships. This process takes into account everything that influences sales, even employing some time series analysis, and limits the number of assumptions in the forecast. If assumptions are made, they are monitored throughout the modeling to insure that they are valid, and the model is continually refined when more information about the business is available.

Whether or not a forecast is accurate is important for sure, but it is not the only value derived from the forecasting process. Forecasting is almost equally a valuable opportunity to reassess the assumptions and estimations a business follows in bringing its products to market as they are a tool to predict the future.

Assumptions and estimations generally produce reasonably accurate forecasts for the immediate future, but assumptions become weaker predictors of the future as the time horizon lengthens.

However, forecasts can be made more reliable if the assumptions and estimations used are supported by preexisting data that is based on solid market behavior drivers. By using data that takes into account why consumers of your products behave as they do, the reliability of forecasts increase.

This is why it is important for businesses to establish a forecast early, refine it as intelligence is gathered regarding their understanding of customer behavior drivers, and iterate to achieve a higher degree of accuracy.

Assessing the quality of past forecasts with respect to their accuracy and consistency with gathered intelligence improve the quality of future forecasts. Generally, forecasting is done internally by the sales and marketing departments, and in larger organizations, by product managers, because they have the best understanding of market demand and customer behavior.

Once you understand what is causing the decrease, you can then pivot your efforts to make up for the lost revenue in other areas. Leadership begins searching for a cause and learns that an existing mandate that required a specific training course they offer was updated and no longer requires that course. In response, they:. The quick diagnosis of the problem affecting their sales forecast, allowed the company to rapidly change their direction. By taking action quickly, they are able to close the sales gap within a more acceptable deviation.

When you understand how things work, you can then identify ways to make them work better. This is true for sales forecasting. If you are consistently forecasting, you can begin to identify areas in the sales process that take longer than they should, have low conversion rates, etc. Once you understand these problems, you can dive into the current process around them and experiment with ways to make it better, knowing that a positive outcome would reduce those bottlenecks in your sales forecast.

This number leads him to believe that his team is wasting the majority of their time on deals they are destined to lose and he would like to get them to a point where their efforts are resulting in more wins. Based on this information, he begins delving deeper into the opportunities that are being opened and the point in the sales process they are being lost.

He finds that his reps are opening a deal as soon as they are assigned a lead and they are being lost because they have not made contact. Based on this information, he creates a new step in the sales process that opportunities are only created once a lead has explicitly shown interest in their offering.
