The sales forecast is comprised of the following concepts:
1. The sales forecasting level is the focal point in the corporate hierarchy where the forecast is needed at the most generic level, i.e. Corporate forecast, Divisional forecast, Product Line forecast, SKU, SKU by Location.
2. The sales forecasting time horizon generally coincides with the time frame of the plan for which it was developed, i.e. Annual, 1-5 years, 1- 6 months, Daily, Weekly, Monthly.
3. The sales forecasting time interval generally coincides with how often the plan is updated, i.e. Daily, Weekly, Monthly, and Quarterly.

Demand Supply Balancing
The process of identifying and measuring the gaps and imbalances between demand and resources in order to determine how to best resolve the variances through marketing, pricing, packaging, warehousing, outsource plans or some other action that will optimize service, flexibility, costs, assets (or other supply chain inconsistencies) in an iterative and collaborative environment.
Demand Time Fence (DTF)
1) That point in time inside of which the forecast is no longer included in total demand and projected available inventory calculations; inside this point, only customer orders are considered. Beyond this point, total demand is a combination of actual orders and forecasts, depending on the forecast consumption technique chosen.
2) In some contexts, the demand time fence may correspond to that point in the future inside which changes to the master schedule must be approved by an authority higher than the master scheduler. Note, however, that customer orders may still be promised inside the demand time fence without higher authority approval if there are quantities available-to-promise (ATP). Beyond the demand time fence, the master scheduler may change the MPS within the limits of established rescheduling rules, without the approval of higher authority. See: planning time fence, time fence.

Direct Store Delivery (DSD)/ Door Delivery










Process of shipping direct from a manufacturer’s plant or distribution center to the customer’s retail store, thus bypassing the customer’s distribution center. Also called Direct-to-Store Delivery

Discrete Available-to-Promise
A calculation based on the available-to-promise figure in the master schedule. For the first period, the ATP is the sum of the beginning inventory plus the MPS quantity minus backlog for all periods until the item is master scheduled again. For all other periods, if a quantity has been scheduled for that time period then the ATP is this quantity minus all customer commitments for this and other periods, until another quantity is scheduled in the MPS. For those periods where the quantity scheduled is zero, the ATP is zero (even if deliveries have been promised). The promised customer commitments are accumulated and shown in the period where the item was most recently scheduled. Also see: Available-to-Promise
