Data Securities International introduced the concept in the mid 1980s for a Total Software Value (TSV) that uses the composites of Ownership Value (OV) or the software inventory, Market Value (MV), and Internal Cost Savings (ICS) as values and influencing variables of software as a financial asset. A TSV software inventory valuation (OV) analysis looks at the sum total (or bundle) of the various software components or intellectual assets that make software usable as a product.[4]
Total Software Value is explained in the book "The Long Journey to Software Valuation" see ISBN 978-1-7344129-0-1 and Copyright Registration: TXu 2-181-571 [5]
