Focus on Fatigue

Focus on Fatigue, Issue 22

Issue #22 – May 2013

Dear Reader,

Welcome to the new year and a new look for InterDynamics and the Focus on Fatigue newsletter.

As it’s been a while since our last issue, we have lots to share, and hope that there is something for everyone in this bumper issue of Focus on Fatigue.

On top of helping organisations make informed, risk-based decisions to manage the risks of and to fatigued workers, we’ve also been working hard on an updated look and improved experience for visitors to our website, in line with our 20th Anniversary. See the Feature Article below for a special message from InterDynamics’ Managing Director Peter Page.

One of the things you will notice with our re-branding is a combining of our previously disparate websites (, and to showcase both our Fatigue Risk Management and Decision Support solutions on the one site:

In recognition of the publicly funded university research (at the Centre for Sleep Research, University of South Australia) that resulted in the formula and factors commercialised within the FAID software, we are proud to continue providing a complimentary evaluation version of FAID on our new site. You’ll also find information on new FRMS Services and Products, FAQs and a new Resources and Media section. We also have plans for exciting new features to come on the site over the course of 2013, so watch this space.

Some things you won’t find anymore however, are references to ‘FaidSafe’, or ‘InterDyne’. In the past InterDynamics utilised the brand ‘FaidSafe’ to refer to its Fatigue Risk Management services and methodology. Nowadays we refer to this offering as Our Risk-Based Approach to managing fatigue.

The company is the same; we’re just simplifying our branding and proudly focusing more on who we are – InterDynamics.

We hope you like the new site and find all the information you need to assist you in managing fatigue and making good risk-based decisions.

Let us know what you think. We’d love to hear your feedback on our new look and site, and how we can serve you better.

Thanks again for partnering with us to make workplaces safer around the world.

Work Safely.

Celebrating 20 years of navigating complexity and delivering clarity

In August 1992 InterDynamics began with a nascent simulation language, SimView (now called Planimate), and a vision to show the world how whole systems worked and interacted. Over the last twenty years Planimate has matured to an extremely powerful tool for modelling systems.

Our experiences have taught us how to create decision support solutions utilising simulation as a core feature. Our capability has extended to include human interaction in systems through the acquisition of fatigue assessment technology from the University of South Australia. This technology was implemented as our flagship Fatigue Assessment Tool, FAID.

FAID® – What you need to know

With 20 years experience providing modelling solutions for large multinationals, InterDynamics understands the importance of end-user decision makers recognising what a model is doing, and what it is and isn’t telling you. The same principle applies when using bio mathematical models such as FAID.

FAID is a powerful decision support tool in the analysis of, and mitigation against Hours of Work related fatigue risks. Like any bio mathematical model however, which (by definition) use general population level data to provide a view of relative fatigue exposures, neither FAID nor any other model in the market can provide meaningful individual level fatigue predictions. Fatigue Risk Management is obviously more than plugging data into a model and looking for a certain number, colour or other metric to provide safe/unsafe (go/no-go) approval.

One of the worst things an organisation can do when managing the risks presented by fatigue, is to over-rely on a model by thinking that it can tell them whether their operations are safe or not with relation to fatigue. To be fair, models don’t (or at least shouldn’t) claim to do anything of the sort.

As Albert Einstein said: “A little knowledge is a dangerous thing.” In order to protect against this, and provide what we feel is an appropriate level of minimum understanding about FAID, we invite you to take a few moments and ‘look under the bonnet’ with us and review your understanding of how FAID works and how to appropriately use the results it provides.

Apart from the document linked above which forms the introduction to the latest FAID v2.1 User Guide, we also offer personalised FAID Training workshops to guide your team of users and decision makers through the functionality and correct context of use.

One last thing to note: The outputs FAID produces have been labled  as “FAID Scores” since version 2.0 (Oct 2007) in a purposeful attempt to reduce the likelihood of organisations mistakenly thinking that the scores FAID produces are representing an individual’s level of fatigue, which on any specific occasion is mediated by other factors including their behaviour outside of work. In later versions of FAID we have refined our expression of what FAID is measuring, and aligned it more closely with the statutory requirements under most OH&S jurisdictions. FAID Scores may be denoted as a measure of the ‘sleep opportunity’ associated with, or afforded by a schedule or roster and is a proxy for fatigue due to Hours of Work-related causes.

If your organisation is still using a version prior to version 2.0 we strongly recommend upgrading to the latest version. Not only will you get access to the great new reports and useability features, but you can rest assured that the outputs and wording will assist in ensuring your team’s correct understandings of what the model is telling them.

Managing Fatigue Training – the first step in cultural change pertaining to fatigue

Targeted communication and education on fatigue is the key to stimulating positive culture, and effective change management on the issue of fatigue. InterDynamics’ Managing Fatigue Training Workshops are the perfect starting point for practical staff engagement and positive behavioural change, leading to increased safety and a better experience of both work and home life.

This two and a half hour workshop is fun, down to earth, practical, and focused on helping workers at all levels recognise the importance, and benefits of taking fatigue management seriously. Valuable insight are provided into the short and long-term issues associated with personal fatigue, strategies for managing fatigue both at work and at home, and getting the most out of a healthy work-life balance.

Feedback on this workshop has been overwhelmingly positive. See what participants are saying from this selection of responses to our participant’s feedback survey.

If your people haven’t all been recently trained on the effective management of their fatigue, we can certainly help.
