Airline mergers generally require aircraft parts and assemblies to be located and tracked in a single provisioning system. JANA can assist with confirming the applicability of part numbers and assemblies against the combined fleet to ensure “Fit, Form, and Function” of each part and identify opportunities for combining stock, thus reducing stocking requirements throughout the system. A significant advantage of this process is that it identifies stocked parts and assemblies that are no longer in use and can be removed from stock and sold.
