DBA is a pure just in time manufacturing system 


DBA is a pure just in time manufacturing system that only responds to current demand that needs action now.  As such it does not include any forecast, hard linking, or shortage report based planning methods. 


Time to Shipment MRP is the DBA version of just in time


Time to Shipment MRP is the DBA version of just in time manufacturing whereby lead time planning is used to calculate time to shipment targets and supply pipeline planning is used to trigger demand-driven, self-adjusting jobs and POs at regular intervals.

 

Bypassing MRP is neither feasible nor desirable


Bypassing Time to Shipment MRP is neither feasible nor desirable because item scheduling allocations, order policies, supply pipeline settings, and demand-driven jobs and purchase orders are required for proper scheduling, meaningful job prioritization, and lean inventory and WIP.


DBA is not designed for alternative planning methods

 

In order for just in time manufacturing to work properly, DBA purposely does not include any shortage reports, BOM explosions, forecasts, or other planning tools that would create incompatibilities with just in time principles and processes.

 

MRP can be applied to any type of manufacturing business


Alternative planning methods are not needed because just in time manufacturing principles and Time to Shipment MRP can be applied to any type of manufacturing business, regardless whether products are made to order, to stock, in mixed mode, engineered or customized to order, or are proprietary or made on behalf of other companies.
