Corrective feedback: addressing the work without judging the person
In precision activities, a frontline manager must be able to point out a discrepancy without leaving the required standard unclear. The useful question is more specific than “how do you give constructive criticism”: does task-focused feedback help people correct their work more effectively than a judgement about the person?
What the literature establishes
Avraham N. Kluger and Angelo DeNisi (1996, Psychological Bulletin) show in a meta-analysis that feedback interventions improve performance on average, but can also impair it. Their theory proposes a mechanism: feedback becomes less effective when it shifts attention away from the task towards concerns about the self. Saying that an employee “lacks rigour” therefore does not provide the same information as describing a check that was omitted.
Information that enables correction
John Hattie and Helen Timperley (2007, Review of Educational Research) distinguish between feedback focused on the task, the process, self-regulation and the person. Their review, situated in education, highlights the value of information that clarifies the intended outcome, the observed gap and how to move forward. For a team leader, this framework suggests connecting an observation to a possible action rather than stopping at a general assessment.
The premature conclusion
One might conclude that making every comment factual is enough to secure improvement. The cited studies do not guarantee this effect: precise information does not, by itself, provide the means to make a correction. If the discrepancy stems from contradictory instructions or unsuitable equipment, asking for greater attention may leave its cause untouched. (our executive and employee training programmes)
What the evidence cannot promise
The meta-analysis brings together varied tasks and settings; the educational review does not constitute validation in precision manufacturing. These studies therefore cannot support a prediction of a specific reduction in non-conformities in a Neuchâtel workshop. Common practice has another limitation: counting the feedback delivered measures managerial activity, not whether the correction is understood or implemented.
A practical check in Neuchâtel
Within SHR’s “Management de proximité” programme, an exercise to test in a Neuchâtel microtechnology, watchmaking or precision microelectronics workshop is to structure corrective feedback around three elements: an observable discrepancy, the required criterion and a next action consistent with quality procedures. During a two-week pilot, record each selected feedback instance and ask the employee to restate the action required to check understanding. Then calculate the proportion of these instances followed by an action that was understood and subsequently completed, distinguishing corrections within the operator’s control from issues requiring a technical or organisational decision. This indicator checks whether feedback is put into practice; it does not, on its own, demonstrate a causal effect on quality.
