Reference Methodology

The Reference Matrix workbook is a structured data set that scores the language, platform, and provider landscape against the severity ramp, and it carries equal weight with the chapters.

The methodology covers the severity ramp, the conservative inclusion criterion, the four scoring dimensions, user-experience prevalence on the Languages sheet, device scale on the Platforms sheet, D5 effects as cross-sheet score, the critical-count summaries, the methodology caveats, and the per-sheet structure of the workbook.
