HFE and Systems Design and Development

In the “Human Factors Engineering Theory and Practice” course, we had a brief introduction to fundamental HFE methods such as task and error analysis. While those methods are useful, to be really effective, HFE techniques must be integrated into design, development, and organisational change processes.

This is because HFE is not just a set of techniques or methods; it is a way of thinking about design and development that prioritises human needs and capabilities. To achieve this, HFE needs to be integrated into the overall design or change process, from the earliest stages of concept development to the final stages of implementation.

Essentially, we need to ensure that HFE accomplishes four objectives when thinking about systems design and development:

1. HFE needs to be systematic or structured. This means that HFE activities should be carried out in a methodical and organised way, using established processes and procedures. Where possible, we should try and use standardised and repeatable processes that have good validity and reliability. We shouldn’t be trying to re-invent the wheel.
2. HFE needs to be done sequentially. This means that HFE activities should be carried out in a specific order, with each activity building on the previous one. For example, in the design of a new medical device, the human factors analysis should be carried out before the development of the user interface. If HFE is not done sequentially, it can lead to delays, rework, and a less efficient design process.
3. The right HFE activities need to be done at the right time. This means that HFE activities should be tailored to the specific stage of the design and development process. For example, a usability study should be carried out once the product has reached a certain level of maturity, but before it is released to the market. If the right HFE activities are not done at the right time, it can lead to missed opportunities, increased costs, and a less effective design.
4. The HFE effort needs to be proportionate to the risks and challenges. This means that the level of HFE effort should be commensurate with the level of risk associated with the product or system. For example, a high-risk medical device will require a more thorough and extensive human factors analysis than a low-risk consumer product. If the HFE effort is not proportionate to the risks and challenges, it can result in HFE not being cost-effective or value for money.

This course tackles each of these four principles, and provides you with the information and skills to incorporate HFE into projects effectively.
