So a buyer can tell a measurement from an estimate. Every figure carries the label of its weakest input, and nothing is edited after it is written.
A savings figure on a dashboard looks equally solid whether it came from a provider invoice or from an assumption. CompletionPrism™ labels every number so nobody has to guess.
A total carries the label of its weakest input. A saving built partly on an estimate is labelled estimated, even if most of it was observed.
A tool that only reports savings is a marketing number, not a measurement. Labels let finance follow any saving to its source and stop wherever they stop believing it. See CompletionPrism™.
