NewEvidence Debt: why impact data fails scrutiny

Accounting for non-financial data.

Evidence you can stand behind

isomerra keeps non-financial data sourced, structured and ready for scrutiny.

  1. Trace

    Follow the answer back to its source.

    See the page or cell behind a number, alongside the calculation used to reach the answer.

  2. Extract

    Read a figure alongside its source.

    Bring figures out of PDFs and spreadsheets while keeping their page, table and row references.

  3. Validate

    Check the numbers before you rely on them.

    Review units, reporting periods and differences between sources. Keep unresolved questions visible.

  4. Map

    Use the same evidence across requirements.

    Connect a sourced figure to the reporting requirements it supports, and review each mapping in context.

  5. Audit trail

    Keep a record of how the answer changed.

    Follow the source, calculation and review history behind a figure when someone asks how it was reached.
