Sustaining human capability in the laboratory

Repetitive sample preparation and concentrated data review often appear to be separate tasks in a laboratory. For the person doing the work, however, they interact: reaching distances, working height, repetition, monitor position, interruptions and time pressure jointly determine whether a process remains sustainable over time.

The white paper “Lean Labor – Die Architektur guter Arbeit” puts it this way (editorial translation from German): “Human sustainability therefore means more than satisfaction. It encompasses preservation, development and the opportunity to make an effective contribution.”

In a QC laboratory, this means that good work should not merely function today. Work design should preserve physical and cognitive capability, enable learning and give employees a meaningful opportunity to raise concerns about errors, strain and potential improvements.

A recurring sample series offers a concrete starting point. Pipettes, tips, sample racks and documentation are arranged within suitable reach zones. Working height and monitor position are adjusted to the task and the person. Preparation, instrument monitoring and review are planned so that demanding repetition and sustained one-sided postures can be recognised and, where technically feasible, interrupted.

5S can support this workplace: defined locations, a clear reset and visible conditions reduce improvised searching and reaching. However, 5S does not replace risk assessment, ergonomic evaluation, sufficient breaks or realistic capacity planning.

Whether the design works must be assessed locally. Relevant observations may include awkward reaches, static postures, repetition, interruptions, rework, signs of fatigue and the ability to raise problems early. Quality, safety and process performance remain equally important counter-metrics.

Review one frequent laboratory process: which strain recurs – and can it be addressed at its source rather than being continually compensated for through attention, memory or physical effort?
