An industrial deal has two tracks, and only one of them is commercial
A factory selling components, equipment or industrial consumables is running two parallel processes with every serious prospect. One is the ordinary commercial conversation: specification, price, terms, delivery. The other is a technical and procedural track that the salesperson can influence but cannot control: the drawing revision the customer design team is working to, the sample the quality department must approve, the plant audit, the vendor registration, the code created in the customer's purchasing system.
Deals do not usually die commercially. They stall on the second track, invisibly, while the sales report continues to show them as active. A pipeline that models only the commercial stages will present a healthy picture of a business where nothing is moving. The routine below tracks both tracks separately, because the action needed to unblock a stalled quality approval has nothing in common with the action needed to close a price negotiation.
