Background of the tools

All of our instruments are diagnostic: the results so you know what you need to address. Task Weighing, OWAT, and Bobit are also easy to apply in new situations (eg new features but also for working with new systems or using new strategies) to predict workload. With the predicted mental workload, it is possible to develop working methods or to distribute work among staff in an effective way (staffing), or to search for better means of support.

IWS (Integrated Workload Scale) is a tool developed by the University of Nottingham. Intergo has translated it for the Dutch situation and expanded it with a standard, a manual and a scoring methodology. Both the perceived workload and the activities carried out are recorded every 5 minutes. This will give an insight into whether the problem lies in the work itself (called Task Demands) or in the working environment and / or personal characteristics.

Task Weighing and OWAT (Objective Workload Assessment Technique) were developed by Intergo and validated extensively. They form a unique set of tools in the Netherlands.

Task Weighing is designed for and together with train controllers/dispatchers (they operate the signals and points). It makes an accurate calculation of the "job demands", and it involves cognitive and physical activities, and various influences such as puzzling, keeping oversight etc..

OWAT is similar to Task Weighing but universally applicable for signaling and control rooms, (process) control and similar tasks.

Bobit is a simple and universal workload tool. It is based on time spent by task or activity and is limited in accounting for type of tasks and working method. As a first exploration and discussion it forms a very suitable means.

ATMOS is a tool that is tailored to the issues relevant for your organization. It consists of a short questionnaire. This may optionally be integrated in an existing (work satisfaction) survey. The questionnaire has a signaling function that is explored further in talks with management and staff.

It is found that simultaneous application of tools in the areas of Task Demands, Working environment and Workload perception leads to greater understanding. It gives a unique opportunity to relate different aspects of workload.

Of course we are also happy to help with implementation. Solutions and (re) designs are usually tested first or deployed on a small scale. We evaluate the final adjustments.

Use of our tools

The choice of application of a particular tool obviously depends very much on the issues at play and the situation that arises. An existing situation with many signals about high workload requires other tools than a new situation. Also, the history of workload related issues may be important to determine which tools are most appropriate. Therefore, in consultation with the client we determine the tool(s) to be used. Our workload model is the basis for these consultations.
