Measuring sustainable employability is the first step towards targeted improvement. More and more organisations invest in employee vitality, but how do you know if your employees are truly sustainably employable? The TNO DIX score lets you measure sustainable employability objectively — at organisation, team and group level.

Developed on the basis of scientific research by TNO. Measures themes at organisational, team and group level.
VitsAll works with TNO to measure sustainable employability. The DIX, developed on the basis of scientific research, measures five core themes — general health, mental workload, work happiness, future perspective and work-life balance — at organisational, team and group level.
This way you know exactly where risks and opportunities lie within your organisation.
You measure sustainable employability with a validated questionnaire that employees complete anonymously. VitsAll uses the TNO DIX for this. Results are reported at organisational, team and group level, so you see exactly where employability is under pressure.
Employees complete the DIX questionnaire anonymously, on average 10-15 minutes per person.
The DIX measures general health, mental workload, work happiness, future perspective and work-life balance.
You gain insight at organisational, team and group level — never traceable to a single person.
We translate the results into targeted interventions, together with our network of 500+ partners.
