Plan tests and analyse data.

RelTest combines experimental design, statistical evaluation and technical product understanding. This turns test and field data into robust conclusions rather than isolated metrics.

Our testing and data analysis services

From experimental design to prediction, the technical question remains the starting point. Statistics is applied where it strengthens the conclusion and supports the decision.

Design of Experiments

What we work on

We define responses, factors and levels, select an appropriate design and account for interactions, randomisation and required repetitions.

What you receive

An efficient experimental plan that enables robust cause-and-effect conclusions with reasonable effort.

Lifetime testing

What we work on

Load profiles, acceleration models, sample size, censoring and evaluation are aligned with the required lifetime statement.

What you receive

A testing and evaluation strategy with defined validity, test duration and statistical assurance.

Field data analysis

What we work on

Usage data, population, mileage, complaints and failure times are cleaned, classified and placed within a robust reference framework.

What you receive

A transparent view of failure behaviour, affected populations and relevant influencing factors in the field.

Prognostics

What we work on

Suitable statistical or physics-informed models describe future behaviour. Model limits and prediction uncertainty are assessed explicitly.

What you receive

A robust prediction of lifetime, failure probability or future need for action.

Where we typically support projects

Data is most valuable when the decision it needs to support is clear before collection begins.

Too many test variants

The potential test scope exceeds time and budget, and a suitable DoE is needed to identify relevant factors efficiently.

Unclear lifetime statement

Test results exist, but sample size, variation or acceleration assumptions still prevent a robust conclusion.

Field and test data disagree

Different reference quantities and usage populations need to be harmonised before a prediction is possible.
