Plain-language answer
What serviceable market can we defend from buyer groups and economics?
The model uses counted accounts, serviceability, buyer, trigger, contract range, source, and confidence instead of a top-down industry percentage.
Short answer
Use evidence that can survive a second reader.
- Serviceable value equals eligible accounts multiplied by expected annual contract value.
- Eligible accounts equal counted accounts multiplied by the serviceable percentage.
- Confidence-adjusted value equals serviceable value multiplied by evidence confidence.
- Raw and confidence-adjusted ranges are shown separately.
