Semiconductor Industry Characteristics
The semiconductor industry is inherently challenging, defined by:
plex, multi-node value web that includes multiple entities and trading partners, driving the need for munication between vendors and customers to manage the demand signal
A significant mismatch between manufacturing lead time (~ 48 days) and order fulfillment cycle times (~ 15 days) that drives forecast-based production
The uncertainty of such forecasts invariably leads to excess inventory
An environment in which a majority of the inventory resides post fab
In wafer banks pre and post test, and in die banks pre and post package, and in some cases as finished goods
As a result, small changes in demand will cause large perturbations in supply resulting in significant inventory management challenges
Impact to Strategic Operating Model: Push to Pull
Total available product to meet customer demand is equal to the finished goods inventory plus the product which can be produced and delivered within the customer's cycle time

Migration from a “Push” system to a “Pull” system is achieved when product is produced based on demand and replenishment needs, and less on forecast
