What Qring is About


Qring serves clients using an Expanded Skill and Knowledge Approach. 

Our reason for this approach can be seen in the following Catch 22 situation (Link).

  • The end user may be well aware of— and not happy with— a situation.

- The problem is that he/she is often unable to formulate the problem so that the right competence/tools can be used to address the situation, because this requires prerequisite knowledge.

- In other words, you can’t know what to ask for until you know what to ask for.

  • The other side of the problem?

- A consultant can’t know client-specific problems or know what to ask for without prior knowledge of the client's problems.

This is why Qring finds it a win-win to share knowledge through our technobabble, an open-minded exchange of ideas with clients, subcontractors, colleagues and suppliers.

This is why we provide a technology-oriented Learn More section, where we offer information and self-study material for end users to become better positioned to make informed decisions on vibration, pulsation, fatigue and noise. Learn More for informed Client decisions
