DSI History
Data Securities International, founded in 1982, experienced consistent growth until its 1997 acquisition by Iron Mountain. During the mid-1980s, DSI introduced the Total Software Value (TSV) concept, a financial assessment framework that integrates Ownership Value (OV), Market Value (MV), and Internal Cost Savings (ICS) to appraise software as a monetary asset. This TSV model measures the combined intellectual properties within software inventories that contribute to their commercial viability.
The TSV framework is comprehensively explained in the publication The Long Journey to Software Valuation (ISBN 978-1-7344129-0-1) and is protected under Copyright TXu 2-181-571.
