BOM explosion is a standard problem for any manufacturing or assembly company.

Ford, GM, Daimler/Chrysler are the canonical examples of such organizations.

A dealer orders a 2005 Magnum XI, with some set of requested features.

The order goes in, and gets recursively exploded into successively more detailed sets of inventory requests.

You need a car; that means you need:

• Chassis
• Engine
• Drive train
• Wheel assemblies, and everything to connect them to the drive train
• Seats

The engine, then, is a subsystem that must itself be exploded into a further bill of materials representing the components needed to build the engine.

Stereo makers (Panasonic, Pioneer, Sony, Harmon Kardon, ...) will have somewhat simpler BOM explosions. You may buy a stereo "system" which consists of:

• Receiver/Amp
• DVD player
• Tape deck
• Speakers
• Cabling

Each of which then explodes into a BOM that leads to drawing inventory.

The explosion reverberates in a number of ways...
