Abstract: Today's e-business processes and operations are variable, complex and intricate in nature. An apparently simple transaction may in fact cross multiple physical, geographic boundaries, involve many trading partners, and trigger actions in numerous other business processes and activities. Because these complexities and interdependencies are too numerous to handle manually, business processes are inherently wedded to business systems. For that reason, when assessing value, it's generally meaningless to separate the two concepts. Instead, a company values the cash inflows and outflows for the unified business process change on both the IT and business unit sides.
The paper discusses concepts for assessing the value of e-business projects. The concepts described outline a framework and language for articulating e-business value rather than strictly defined valuation formula. After the e-business metrics background is discussed, seventeen representative measures of e-business value are explained, including:

Days of Inventory Reduction
Days of Receivables or Days of Sales Outstanding Reduction
Headcount Reduction and Avoidance
Headcount Productivity
Headcount Turnover
System End-of-Life
Materials Discounts
Capital, Hardware and Software Avoidance

Unit Cost Avoidance
Factory Uptime
Scrap Reduction
Risk Avoidance
Time-to-Market
Opening New Markets
Optimizing Existing Markets
Cross-selling
Vendor-of-Choice
