Overview of the internal audit framework SMACTR. Gray indicates a process,
and the colored sections represent documents. Documents in yellow are
produced by the auditors, blue documents are produced by the engineering and
product teams, and green documents are jointly developed. ADHF = algorithmic
design history file, FMEA = failure models and effect analysis, SMACTR =
scoping, mapping, artifact collection, testing, and reflection. (Adapted,
