Induced volatility

How is he/she able to the subproceso of generation of the demand to help to reduce the variability in the demand? Some companys has realized that they are their own politicians of prices, billing, minimum size of order, etc. those that induce the consumers to present such a volatile demand. A typical example of volatility induced in the demand is the one generated by the promotions of prices. For some products, a promotion of prices doesn't generate a bigger consumption but a pick in the sales during the promotion and a valley in the immediately later period. Take for example, the case of the toothpastes, where a promotion of prices can induce the clients to buy more during the promotion (upgrading future purchases). however, in spite of having bought more, its habit of buccal cleaning will continue being the same one: not to have tooth they will clean more the teeth. The global effect of the promotion of prices can have taken to the company to capture clients of other marks, but this punctual increment in the sales it should be compared with the logistical costs of the promotion to determine if it has been or not efficient. To reduce the fluctuations in the demand some organizations, as Walmart, Asda and Mercadona, they have implanted the well-known strategy of prices as "Every Day Low Price" (EDLP) that consists in not to carry out promotions of prices and to try to offer the clients the same price "I lower" every time that you/they visit the supermarket, as Walmart, Asda and Mercadona.

The synchronization of the logistics and the demand has to do with the elaboration of the forecasts and the synchronization of the necessary logistical activities to serve the clients. This subproceso is intimately related with the previous one, since a less volatile demand allows bigger accuracy in the forecasts and, for so many, to improve the synchronization of the logistical activities with the demand.

The time that the clients are willing to wait to receive the product or service (customer lead cheats) and the time of total supply (the one required by the company for the provisionings, the production and the distribution) they will determine how the logistical activities can be synchronized with the demand. All the companys with a difference among these two times of supply bases their synchronization with the demand on the forecasts, be used to decide what to buy and/or what to take place.

A bigger accuracy in the forecasts bears a reduction of inventories, a decrease of stock ruptures and a better service to the client (for the executions in the quantities and delivery dates). AND everything is translated it in some smaller costs (for decrease of inventories and better use of the Resources) and some bigger revenues (for decrease of stock ruptures).

To improve the forecasts many companys of the sector of distribution of products of great consumption they have adopted programs of continuous reaprovisionamiento (CRP - Continuous Replenishment Programs) or of CPFR (Collaborative Planning Forecasting & Replenishment). A CRP consists in that the maker gives to the distributor in function of the real sales and the stock levels that this has of the product in question. The maker has visibility "almost" on time real on the sales of his product in that distributor's establishments; and based on her he/she decides how much to send (the distributor no longer makes orders). The biggest visibility on real levels of sales allows the makers to improve their

forecasts and to synchronize the production better with the demand.

In a program of CPFR, makers and distributors don't only collaborate in the reaprovisionamiento but also in the elaboration of the forecasts. The CPFR consists basically on comparing two forecasts (that of the maker and that of the distributor) and to decide which it is more correct. The comparison is carried out using the new TIC and the installation of softwares of CPFR. In this type of programs the maker doesn't only have bigger visibility on the real sales but rather it improves his forecasts sharing them with the client.
