“ The character of the records compiled from this data determines the real value of the entire system of cost accounting. If, as is so often the case, the compiling extends no farther than a mere tabulation of costs of individual jobs, it does not reach its full value as a part of the accounting records. Like single-entry bookkeeping, such records are no more than mere memoranda. The full value is reached only when the records of the cost department are made a part of the general accounting system of the business; where controlling accounts absorb all individual items of cost. ”
