    The source supports the metric half (TLX ratings diagnose the source of workload to guide modification) but not the interview, redesign and re-measure cycle.

    “By identifying the specific source of workload in a task it pro- vides a basis for deciding how to modify unacceptably high levels of workload”

    Hart and Staveland show global workload ratings blend different sources and mask causes, and that source-specific ratings guide how to reduce workload.

    “they may reflect time pressure for one task, varia- tions in effort in another, and different levels of decision making complexity in yet another.”

Verification

Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.

Does it back the claim? Read against the text for 2 of 11 citations: 2 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
