When a serious workplace injury occurs, our instinct is often to look for the immediate cause. A machine guard was missing. A worker took a shortcut. A process was not followed. These factors matter, but they are rarely the whole story.
In my experience, the more useful question is often: how was the work designed in the first place?
Across New Zealand manufacturing, businesses are operating in an increasingly demanding environment. Production targets are rising, skills shortages persist, supply chains remain under pressure, and many workplaces are being asked to do more with fewer people. At the same time, manufacturers face growing expectations around safety, wellbeing, productivity and quality.
These challenges may seem separate, but they are closely connected. The way work is designed influences each of them.
The concept of good work design is not new. Internationally, ergonomics and human factors specialists have spent decades studying how work systems affect safety, health and performance. ISO 6385, the international standard covering the design of work systems, takes a systems approach that considers people, equipment, work organisation and the environment together rather than in isolation. Research consistently shows that when work is designed around human capabilities and limitations, businesses achieve better safety, wellbeing and performance outcomes.
Yet many manufacturing environments were not intentionally designed as complete systems. Instead, they evolved over time.
Production lines were extended to meet demand. New machinery was added where space allowed. Responsibilities shifted between teams. Reporting requirements accumulated. Extra shifts were introduced. One practical solution followed another until the overall system became far more complex than originally intended.
As a result, many workplaces now operate with systems that no longer reflect how work is actually carried out.
That matters because workers are often the ones bridging the gaps.
When production flows become constrained, workers adapt in real time to keep output moving. When processes are unclear, they create workarounds. When workloads increase, overtime becomes the solution. When staffing levels are stretched, experienced workers compensate by taking on additional responsibilities. These responses often keep businesses operating, but they can also introduce hidden risks.
Research into work-related musculoskeletal disorders and workplace harm increasingly points to organisational and system factors rather than individual worker behaviour alone. WorkSafe guidance similarly highlights that poorly designed tasks, systems and environments can contribute directly to both physical and psychological harm.
Manufacturing provides plenty of examples. Poor workstation layout can contribute to long-term musculoskeletal injuries. Repetitive manual handling tasks can create cumulative strain over many years. High-speed production environments can increase cognitive workload and reduce opportunities for recovery. Shift work, fatigue and excessive overtime can affect concentration, judgement and decision-making.
These are not simply health and safety issues. They are business and operational issues.
Project Whakahaumaru, the manufacturing sector’s Harm Reduction Action Plan, identified work design as a key area requiring attention. During consultations with workers, leaders and health and safety practitioners, a recurring theme emerged: many businesses wanted safer outcomes but lacked the time, resources or capability to deliberately design safer systems of work.
The cost of getting it wrong can be significant. Serious injuries can result in fines, reparations, production disruptions and regulatory scrutiny. Less visible harms can be equally damaging. Fatigued workers make more errors. High levels of discomfort contribute to absenteeism. Poorly designed jobs can increase staff turnover at a time when many manufacturers are already struggling to attract and retain skilled workers.
Reputation also matters. Customers, investors and workers increasingly expect businesses to demonstrate that they manage their people and operations responsibly. A serious health and safety failure can take years to recover from.
Good work design offers a practical way forward.
It requires thinking about how workplace layouts influence movement and material flow. It means understanding how production targets affect workload and fatigue. It means considering workforce demographics, including an ageing workforce and changing skills requirements. It means ensuring equipment, tasks and processes are designed around the people doing the work, rather than expecting workers to continually adapt to poorly designed systems.
Most importantly, it means involving workers in the conversation. The people performing the work every day often have the clearest understanding of where pressures exist, where inefficiencies occur and where risks remain hidden. Their experience provides insights that cannot be found in procedures or organisational charts.
Good work design is not a compliance exercise or a safety programme sitting alongside the business. It is part of how a well-run business operates.
The manufacturers that will succeed in the years ahead will be those that recognise that safety, productivity and wellbeing are not competing priorities. They are all shaped by the same underlying system.
If we want fewer injuries, stronger productivity, lower turnover and more resilient businesses, we need to begin where those outcomes are created: in the design of work itself. Safety should not be left to chance. It should be built in from the start.
