He argued that traditional cost accounting — despite its apparent rigor and universal adoption — is structurally defective as a management framework because it treats all costs as equally important, all revenue as equally desirable, and all departments as independent units to be measured independently.

The defect manifests in specific ways. Cost accounting treats inventory as an asset because inventory has financial value that can be sold — and ignores that inventory is simultaneously a liability that ties up capital and consumes management attention. It measures departmental efficiency through utilization — and cannot see that a department running at full capacity may be producing waste if its output piles up in front of the system constraint. It rewards cost reduction in
