A product-operations case, a data-classification pipeline, and DORA framing illustrate three different evidence levels: usage, process change, and an accepted operational result.
New Runtime reading: Mixing those levels produces unsupported ROI claims. A defensible case names its baseline, review burden, acceptance boundary, and whether the metric is vendor-reported or independently observed.
Evidence boundary: this item uses the listed public sources and keeps vendor, author, or reporter claims attributed. The queued page is an editorial synthesis, not an independent validation of every reported metric.
