Ergonomics and Human Factors

Ergonomics at work

Human factors

When you're good, you're better

For more than forty years, Human design Group has been shaping changes in the workplace by demonstrating that design rooted in ergonomics and human factors makes a positive contribution both to people's health and to the efficiency of organisations, making working conditions a strategic asset for overall performance.

This conviction, which has been verified and nurtured by the experience gained from hundreds of projects, is now taking on a whole new dimension: robotisation, artificial intelligence, hybrid work and longer careers mean that the balance between performance and well-being has to be constantly readjusted. As P. Falzon points out, it is precisely in the tension between productivity and people that ergonomics reveals its systemic value, shedding light on the hidden costs of performance and new levers of competitiveness.

To meet these challenges, Human design Group deploys an integrated approach. By measuring physical, cognitive and organisational constraints using field sensors and demanding activity analysis, we know how to prevent wear and tear. By aligning tools, spaces and processes with actual usage, we support change and skills development, guaranteeing the long-term viability of solutions that have been tried and tested in real-life operational situations.

Navigating transformations

We are delivering tangible results: reduction in muscular effort following the redesign of a reaction arm; keeping field operatives in work by adjusting career paths and certain critical actions; optimisation of an industrial macro-zoning system reducing non-quality and the risk of falls while speeding up production, etc.

By transforming every constraint into a design opportunity, Human design Group helps companies to build safe, agile and attractive organisations, ready to combine economic performance, social responsibility and quality of life at work to transform working conditions on an ongoing basis.

What contribution do neurosciences make to our understanding of working conditions?

Sharing a common vision of a work situation is the first step in transforming that situation. 

Using sensors to measure stresses can be a methodological solution for :

  • Give weight to the words of operators or users
  • Anticipating the effects on health
  • Highlight the potential gains 
  • Supporting projects: comparing technical solutions, calibrating expected performance with the terrain and human capacity, etc.

The measurement systems developed by the Human-System Research and Innovation Centre (CRIHS) of Human design Group include easy-to-deploy field sensors with advanced data monitoring, processing and synchronisation systems.

Aerospace X Manufacturing

Objectivising human performance

Complement ergonomic diagnostics with sensors and targeted measurements to improve human factors data, refine information and measure experience.

Ergonomic diagnosis to validate the need for and usability of reaction arms on an aeronautical production line.

After an accident at work, and usability questioned due to excessive weight, the reaction arms were withdrawn for low-torque screwdriving, with the introduction of a lighter version and modulation of the screwdriving programmes. 

However, these significant adaptations were not unanimously supported.

  • Identification and comparison of muscular impacts for different postures, programmes and pairs
Anticipate

Can we reconcile professional wear and tear, longer working lives and attractiveness?

An ergonomic diagnosis of the working conditions of today's employees means : 

  • Always take a preventive and constructive approach: look for conditions that not only prevent deterioration in health but also help to build it up (1); all the more so at a time when the retirement age is falling,
  • But we also need to have a differentiating approach: making working conditions an attractive factor in terms of employment; all the more so at a time when the relationship with work and commitment in sectors that experienced a slowdown during COVID have changed the employment market.

Airport & Organisation

Objectivising working conditions

Improving working conditions to protect health, develop individual and collective resources, improve performance and make it an attractive factor.

Ergonomic diagnosis to assess and adjust working conditions in airport jobs to ensure that staff remain in employment

How can we manage the difficulty of airport jobs in a context where working life is getting longer and the attractiveness of jobs is becoming more important post-covid? What solutions can be put in place to help people stay in work: adapting working conditions, defining career paths, managing burnout?

  • Implementation of an ergonomic study to objectivise working conditions and the associated levers.
  • Identification of ways to improve working conditions, and areas to be maintained and strengthened Definition of career paths Improvement of prevention policy: monitoring, awareness-raising.

Revealing new sources of value by improving working conditions?

As P. Falzon (1) reminded us, The specificity of ergonomics lies in its tension between two objectives: organisation and performance (efficiency, productivity, quality, reliability, durability, etc.), and people (safety, health, comfort, ease of use, satisfaction, interest in the work, etc.).

Exchanges with other disciplines (2) (socio-economics, political science, management science, etc.) show and measure that the quality of work and the commitment of operators are key factors in performance. These approaches make it possible to objectify malfunctions, model invisible costs and anchor the human factor as a driver of systemic efficiency.

2. Collective (2023). What do we know about work?

Human design Group develops strategies and implementation plans that maximise performance while minimising the resources and effort required. This requires an analysis of current and future operations, an approach that often incorporates innovative methodologies and appropriate technological solutions.

Highlighting hidden costs

Objectivise working conditions to show the cost of malfunctions (errors, absenteeism, lack of quality, etc.) and the potential benefits of changes.

How to control a pipe
of change centred
on working conditions?

Against a backdrop of constant organisational and technical change, mastering the process of change management and getting users on board are key to the success of any project. 

Because it is grounded in the field and systemic in nature, business analysis offers added value and a real differentiator compared with other approaches to enriching transformation projects with data relating to the «last few kilometres» to be integrated for :

  • Adapting their target and the means of reaching it (including hidden costs)
  • Defining measures of the operational efficiency of projects integrating human factors

Human design Group supports transformation projects:

Analysing activities in real or simulated situations

Identifying business anchors and hidden costs

Specifying and managing the means of transition

Measuring operational efficiency through FOH

Cybersecurity & Nuclear
