Solution: Policy-Oriented Enterprise Management

"Enterprise Physics" Radically Simplifies Software Engineering

Example Rule¹: IF STATUS(Supplier) < 20 AND Supplier = Shipper
THEN QUANITY(Shipper) ≤ 500

Associated checks do not now have to be procedurally encoded in routines such as:

Create New Shipment

Change Shipment Quantity

Change Supplier Status

Reassign Shipment to Different Supplier

Fewer opportunities for inconsistency and easier to find if occurs.
(Not yet considering services that change state.)
