HCD.24:5.3 - Retaining a warranted recommendation

A separate constructed instrument-check exercise supplies two reference values, 0 and 100 units, with a permitted error of ±1 unit. Repeated readings are 6 and 6 at the first reference and 106 and 106 at the second. The training procedure permits referral to a qualified calibration service after repeated checks outside tolerance. It does not require the learner to identify the failed component before making that referral, and it does not authorize the learner to adjust the instrument or declare it fit for return.

The author recommends the permitted referral and a new check before the instrument returns to use. The peer objects: “You have not distinguished a sensor fault from an electronics fault; withdraw the recommendation until you can.” The author accepts that the physical cause remains unknown but rejects the requested withdrawal. Both pairs of readings are six units above their references, outside the stated tolerance. The recommendation invokes the supplied referral criterion; it does not claim a component diagnosis or prescribe an adjustment.

A prepared instructor receives the disputed recommendation, readings and procedure. The narrow question is whether the missing component diagnosis defeats this next action. The instructor confirms that the referral criterion is met and explains the separate authority needed for adjustment and return. Both learners receive that resolution. The author retains the recommendation and its bounded ground. The reviewer withdraws the cause-demanding objection and replaces it with a supported judgement: the referral follows, while the cause and fitness after service remain to be established. The correction changes the reviewer’s own criterion application instead of merely marking the author’s comment resolved.

After the initial reading and comments, this example reserves a ten-minute shared window: three minutes for the author’s ground, four with the prepared instructor, and three for the corrected review and author’s response. The resolution therefore adds twenty learner-minutes and four instructor-minutes; initial preparation and review are counted separately. If the instructor must first reconstruct the procedure or the dispute remains unresolved, that larger requirement returns to the arrangement. A later independent case, if required, tests the reviewer’s new judgement; the helped correction alone does not establish it.
