2.4.4. How Utility, Warranty, Experience, and Sustainability Contribute
💡 First Principle: The four value dimensions from 2.1.7 don't just describe value — each contributes to co-creation in a specific way, and seeing how turns them from definitions into reasoning tools.
Each contributes distinctly: utility contributes by providing the functionality that makes a desired outcome possible (no utility, no outcome); warranty contributes by making that functionality dependable enough to rely on (no warranty, the outcome is unpredictable); user experience contributes by shaping whether people willingly and effectively use the service (poor experience suppresses value even when utility and warranty are fine); and sustainability contributes by ensuring value can be maintained over time without unacceptable long-term costs to economy, society, or environment.
⚠️ Exam Trap: Utility and warranty together are necessary for value, but Version 5 stresses that experience and sustainability are now first-class contributors too — a service that's useful, reliable, but miserable to use or environmentally reckless creates less value than its utility/warranty alone would suggest.
Reflection Question: Why does Version 5 treat sustainability as a contributor to value rather than a constraint on it?
