Research has shown that our body also plays a significant role in our brain performance. If we lack enough energy, we will go into a survival mode. This means that our executive functions get less energy. The executive brain consist of crucial elements for project management. By better managing energy, we can improve brain performance and leadership. 

HRV gives us insights into stress and recovery. It also provides insights into the performance of our executive brain. Here are a few examples with links to scientific research. 

We help to improve the executive functions by improving people's lifestyle.

Crystal Clarity uses data and scientific research to help the executive perform better. With small sensors we measure the body 24/7. This data is an important part of our executive coaching program. Our program has two purposes. The first objective is to improve productivity. The second goal is to improve the quality of life. In order to achieve this, we support the change in behaviour.

We improve productivity by improving the performance of the executive brain. Examples of executive functions are: dealing with emotions, adaptability, self-reflection and learning ability. These positions are important for a Project Manager to make wise decisions.

The measurement shows how the body reacts. We see which moments are stressful and which are soothing. This is confrontational. It helps the participant to reflect on the quality of his life. We strive for more rest and energy at work and at home.

Comments from participants:

"This is kind of confronting. I can't get around my data."

"It's a fun game to score better and better."

"I feel much more productive."

"People see that I respond more relaxed."



Measuring body and behaviour

This measurement takes 3 days. It reveals what affects well-being and performance at work, leisure and sleep.

With these sensors we measure heart rate variability (HRV). This gives us insight into effort (stress) and recovery moments. Together with the participant's notes and agenda, we get a detailed insight into the effect of behaviour.


On the basis of this measurement, the participant receives a report and an advisory interview.

In the counselling interview we look at:

  • What causes stress

  • Sleep rhythm

  • Sleep quality

  • Recovery during work

  • Recovery in private time

  • Effort during work

  • Effort in private time

  • Energy level

  • Fitness level

Crystal Clarity cooperates internationally with other training agencies. As a result, we have a large database of scientifically based and applicable solutions at our disposal.

Trend measurement & Gamification

We have an accurate overview of the participant's improvement points. We will continue to measure the progress over a number of months with the help of a smartwatch. This watch contains sensors that also measure HRV. This is accurate enough to measure a clear trend.

The participant has 24/7 access to his own data. This allows for more conscious choices to be made. In addition, the data provides an element of play. It's addictive to get better and better scores.


Measurements are only meaningful when we take them in a specific context. That's why we link the data to the calendar. This allows us to identify which events give energy and which ons suck energy away. This will enable us to recognise patterns. MAHOUT is the software program that converts the "raw" data into usable data. It is an easy to use program to connect to your OUTLOOK calendar. In addition, you have plenty of room to make personal notes. We use this information to further develop the participant.


We have regular contact with the participant to discuss progress. This is an encouragement to change behavior. It also provides us the opportunity to coach.



  • Productivity increases

  • Our executive functions perform better.

  • Participants come home with more energy and pleasure.

  • Address signals that lead to burn-out.

  • 85% of the coached participants feel more effective

  • Up to 30% less sick leave

  • Proven method to motivate participants to exercise and continue training.


Examining the heart provides us with an enormous amount of information about our bodies. Our heart rate is constantly changing to meet life's needs. Heart rate variability (HRV) means the variation in time between successive heartbeats. It is universally accepted as a measurement point of activity of the autonomic nervous system (ANS).

HRV increases during relaxing and restorative activities and decreases during stress. Therefore, HRV is usually higher when the heart beats slowly and decreases as the heart beats faster. In other words, heart rate and HRV generally have a reversed relationship.

HRV changes from day to day based on activity levels and amount of work-related stress. In addition to these external stress factors, internal stress factors cause variation in the daily HRV levels. Internal stress factors include poor nutrition, alcohol consumption, illness, etc.
