FDM.Preface:5 - Practical gain, cost and evidence

The first gain is a smaller, better defined question. A payment report may need only a corrected party reference or a distinction between due and paid. A service design may need to locate who actually uses a score. A disputed obligation may require the applicable institutional rule and evidence of the event it recognizes.

A detailed model costs time to build and maintain. Begin with an adequate existing account and deepen it where a plausible alternative changes interpretation or action. A qualified model, demonstrated non-change or precisely located unknown can be the first useful result.

Recognition and assurance have different jobs. A score presented as a benefit or an aggregate presented as available cash is a reason to examine the account. An actual financial-effect claim needs adequate support for the parties, applicable terms, occurrence and consequence it asserts. A quantitative benefit claim also needs evidence for its comparison and uncertainty. The numerical cases here are constructed under supplied terms.
